Hose Safety and Reliability in Mining

The mining industry, known for its harsh and unforgiving environments, demands reliable, high-quality equipment to ensure safety and efficiency. Longwall mining, which accounts for around 50% of total underground production, has had the largest continual impact upon underground coal operations in the U.S. over the last two decades.

Longwall mining is an underground mining operation in which a large panel or block of coal spanning up to 1,500 ft across distances of two to three miles is extracted. Longwall mines are characterized by low ceilings and tight spaces in which workers must operate heavy machinery. Hydraulic-powered roof supports, also called shields, protect the working area of the mine by extending as a shearer cuts back and forth along the coal face. Once it is cut by the shearer, coal falls onto a large chain conveyor for transport to the mine. The movable hydraulic shields in longwall mines advance with the shearer throughout the mining process, enabling increased productivity as well as improved safety for miners.

Safety is imperative in the mining industry, particularly when it comes to the dangers of roof falls and lack of clean air in underground coal mines. It is vital for the equipment used in mining to be thoroughly tested to meet internationally approved MSHA standards and provide consistently reliable performance to ensure safety of operations and individuals in extreme environments.

High Performance for Mining
Because of the rigid safety and performance requirements for mining equipment, Parker Hannifin and other major hose manufacturers offer products designed specifically for mining applications. Parker’s GlobalCore 187 hose is a 1,000 psi (7 MPa) constant-working-pressure hose specifically engineered for the mining industry. ISO 18752 requires impulse testing at 133% maximum working pressure and 100°C for 200,000 cycles for standard and compact type hoses. GlobalCore 187 hose exceeds these requirements and can be used as a high-pressure return line or where other hoses may be overkill or requires a lower bending force.

Making Sense of Hydraulic Hose Standards

Hydraulic hose construction and performance is covered by various national and international standards including ISO, BSI, SAE, DIN, API, and CETOP. Most proprietary hoses conform to one standard or another, the SAE standards being the most widely followed in the U.S. SAE standards provide general, dimensional, and performance specifications for the most common hoses used in hydraulic systems on mobile and stationary equipment.

For decades, SAE J517 has published guidelines for 100R1 through 100R12 series hydraulic hoses. These manufacturer-driven SAE standards have been based on design, construction, and pressure ratings to ensure that hydraulic hoses meet minimum construction requirements. SAE established minimum pressure ratings for various hoses (inside diameters and were later revised to also include constant-pressure hoses, which are hoses that maintain pressure ratings within a group regardless of size). Some common constant-pressure hoses are R13, R15, R17 and R19.

Applying Thermostatic Principles in Impulse Testing of Hydraulic Hose

A multitude of thermostatic principles specifications can be selected when certifying hoses and other hydraulic components—from a simple proof set up to the most sophisticated test requirements. Each segment or product has its own set of standards and these norms are constantly under either revision, implementation or being created when new material or innovative applications become a reality.

The widespread use of a product usually requires a set of standards to accompany it. Automotive, aerospace, industrial hydraulics, and most recently CNG applications, can be listed as some of the more complex hose tests. Traditional testing concepts must give away for more effective testing procedures, as well as the fact that other testing parameters are also to be measured. This is especially true when the complexity of a thermostatic impulse testing of hydraulic hoses is required.

When a thermostatic environment is combined with an Impulse Test, new testing parameters have to be measured and a new set of variables must to be taken into the equation. Another factor that has to be deeply analyzed is how the specs define the test procedure. Sometimes even the specs are not as forthcoming as one would wish and the interpretation of which may require further investigation.

There are some international standards largely covering impulse test stand with a thermostatic chamber. For instance, in aerospace, the SAE standards, AS series has some publications dedicated to testing of coupling, fittings, hoses, and tubing assemblies. Besides demanding impulse tests, some of these specs require ambient temperatures either below-zero or well above chamber temperature. The test equipment has to simulate the environment in which an airplane is exposed. There are also National Aerospace Standards, which require temperatures below 0°C when running pressure cycles.

Tube Hose Replacement: Do it Right the First Time 

All of those excavators, loaders, bulldozers, and other heavy machinery typically working at a construction site have a common vulnerability: They’re only as reliable as the hoses through which all of that hydraulic fluid travels. A sudden rupture not only halts work abruptly, but can also cause a spill that endangers the surrounding environment. It can happen without warning. And even if the hose doesn’t rupture, high-pressure hydraulic fluid leaks can seriously injure workers.

When a hydraulic tube hose does fail, you have two options. One is to have a member of the team carefully attempt to replace the hose. The other option—and the one that’s more reliable and far safer—is to have a hose professional come out and replace the hose. The hose pro knows the ins and outs of hose replacement and has the right equipment experience to get the job done according to specifications.

Some equipment managers keep a stock of hoses and a crimper for such emergencies as this. But simply having those tools isn’t enough. Knowledge and attention to detail are critical. Improper technique in replacing a hydraulic hose can lead to a host of future problems with the equipment.

Anyone who attempts to replace a hydraulic hose must have the proper training. It may seem like a simple, straightforward procedure, but there’s more to it than people think. If your supplier provides such training, take advantage of it. Make sure the person replacing your hoses knows how to do it properly.

 

If you do opt for a do-it-yourself remediation of a ruptured hydraulic hose, proceed with care. Educate yourself, because there’s more at stake than just the hose. Anyone at your company working with hydraulic hose should have a Fluid Power Connector & Conductor Certification from the Fluid Power Society. This program is intended for those who fabricate, assemble, and test hose and assemblies. Connector & Conductor Certification requires a three-hour written and a three-hour, hands-on job performance test.

Keep it Clean
Cleanliness should be a top priority. The close tolerances in hydraulic valves, pumps, and actuators make clean parts critical when fashioning a hose assembly. Contamination is always a danger during hose replacement. This has held especially true since the advent of sophisticated electronics in pump systems—it now takes considerably less contamination to trigger a failure.

These contaminating particles come from a variety of sources. Some originate in the tank and make their way into the hydraulic hoses. Others result from erosion within the system, whether from chemical breakdown or friction over time. One of the most serious and prolific sources of contamination remains the hose-cutting process itself, but more on that later.

Even when the person doing the work is careful, fine particles can end up in the hydraulic fluid. In addition to keeping the hose itself clean, make sure the entire bench is free of grit and contaminants.

Hose and tubing assemblies

Components on many types of Hydraulic Hose and Tubing Assemblies are connected by rigid tubing. Being rigid, however, tubing can transmit vibration from one component to another throughout an assembly. Increasingly, designers of hydraulic systems are integrating bent tubes and hoses into hybrid bent assemblies. These assemblies provide the weight and bend advantages of bent tube with the flexibility and vibration dampening characteristics of hose.hybrid tube/hose assemblies combine the benefits of hose and of rigid tubing for optimum performance.

Metal tube is economical and exhibits a long service life. For equipment manufacturers, bent tubing has traditionally offered additional advantages over hose such as:

  • better heat dissipation
  • smaller allowable bend radii
  • lighter weight (which is important on long boom arm applications), and
  • the ability to handle pressures above 6,000 psi.

Tubing can take a great deal of punishment under tough service conditions. Seamless and welded steel tubing conforming to SAE standards is widely used in medium and high-pressure applications. Stainless steel tubing is used in very high-pressure applications or where corrosion of carbon steel presents a potential problem. (Copper tubing also can be found, but mainly on low-pressure applications.)

On the down side, tubing is subject to corrosion unless it is specially treated. In addition, it must be shaped using sophisticated bending equipment and may require special fittings and considerable labor to install.

Hose assemblies, on the other hand, are less likely to transmit vibration because they tend to dampen pressure surges and pulsations. This ability to absorb vibration not only reduces noise, but helps improve reliability and extend the life of the hydraulic system.

Lighter, stronger, more flexible

At one time, equipment manufacturers specified hose primarily when dynamic bending of hydraulic lines was necessary. If the hydraulic line didn’t need to bend, metal tubing was almost always preferred. Today, designers of mobile equipment in particular are learning to optimize designs by specifying hybrid steel-tube/hose assemblies – especially in applications where vibration is severe. A feasible alternative to port-to-port steel tube assemblies is to connect steel tubing to a port, then run a length of hose to the other component. Some designers even replace steel tubing altogether with a single hose assembly when application parameters permit.

An example of how hybrid steel-tube/hose assemblies work together is exhibited on agricultural equipment that include 60-ft long boom attachments. In the past, manufacturers have preferred to use bent tube assemblies on these attachments in order to minimize weight and prolong the life of the tool bar. However, manufacturers today recognize that these attachments generate vibration, which is a major factor leading to system failure. Their solution to this problem has been to use primarily hose assemblies where the structure can tolerate the higher weight and a bent tube/hose combination where light weight is more critical.

Hydraulic Hose Handles the Pressure, and the Heat

Growing demands for equipment that’s productive, efficient, and easy on the environment increasingly means hydraulic systems must work at higher pressures, withstand higher temperatures, and be compatible with environmentally “friendly” fluids, all while lasting longer. These requirements certainly hold true for hydraulic hose.

Engineers designing fluid-power circuits often follow the “STAMPED” process for selecting hydraulic hose and couplings. Developed some years ago by the National Assn. of Hose and Accessory Distributors, the acronym relates to the seven major areas of consideration for hose selection: size, temperature, application, material, pressure, ends, and delivery. As manufacturers respond to tougher applications with a myriad of new hoses, it’s a good idea to revisit these selection factors.

Size
Designers must adequately size the inside diameter of a hose to minimize pressure loss and turbulence. Turbulent conditions reduce efficiency and generate heat that can damage the hose. Nomographic charts (such as the one shown nearby) can help engineers size hoses for given hydraulic conditions.

Fluid velocity should not exceed the values shown in the right-hand column brackets. Higher velocities in pressure lines are generally acceptable for short durations. However, fluid velocity in suction lines should always fall within the recommended range to ensure efficient pump operation.

When replacing a used hose assembly, read the layline printing on the side of the original hose to determine size. If the layline is painted over or worn off, cut the old hose and measure the ID. Prior to cutting, measure the overall length and coupling orientation. This will make it easier to build a replacement and match the couplings to mating ports.

Do not use outside diameter to identify the hose ID — save for a few exceptions. (See “Sizing hose and couplings.”) Hoses vary with the wall thickness and OD, even though ID may be the same. OD is a factor when hose requires clamps or goes through bulkheads. Here, it is best to check individual hose specifications.

Hoses that meet or exceed SAE (Society of Automotive Engineers) performance specs but are smaller than standard hose can be good choices. Thanks to better materials, “hybrid” hoses have thinner tubes and covers, smaller-diameter wire reinforcement, and more-aggressive braid-reinforcement angles. The result: hoses with the same ID but smaller OD, making them more flexible and 10 to 15% lighter than earlier-generation products.

Hose Clamps Clamp Down on Problems

Unrestrained hydraulic tubing can emit sound as though it were a tuning fork. Fluid velocity, pressure, and line size all contribute to the high-frequency vibration, line shock, pressure surge, and sound, which are prevalent in many hydraulic machine operations. Shock, pressure surge, and vibration will flex metal tubing. This flexing can cold-work the tubing, particularly around connectors. The consequences are split fluid lines.

Accordingly, the fastening components used have progressed from simple clamps to specially engineered pipe and tubing supports. A properly designed and installed piping-support system can reduce noise pollution, risk to property and personnel, and environmental damage caused by the discharge of hydraulic fluid from a damaged line.

Effects of Vibration

Pipe supports should control vibration and absorb shock. Pumps and valves are the greatest cause of vibration and shock, owing to the drastic pressure and fluid velocity changes that occur in these components during operation. While intensive research has reduced pump- and valve-induced vibration, it is still considered a problem for the entire piping and tubing system. Through piping and tubing, vibration, shock, and related noise are transmitted and amplified. Note that pumps are the greatest source of noise, and reservoirs provide the strongest amplification.

Excessive noise for plant personnel is only one negative effect. More importantly, if pipes and hoses are not properly supported, vibration may cause fittings and flanges to loosen. This can lead to increased safety risks for plant personnel, downtime, higher maintenance costs, inefficiency of the system (due to air causing cavitation in pumps and valves), and loss of hydraulic fluid. It is no overstatement to say that the cost, danger, and other consequences of hydraulic leaks as a result of loose fittings and flanges can be alarming.

Resilient Supports

Resilient supports have been developed to dampen the vibration in piping systems. Several types of supports are available that absorb shock and vibration to different degrees. These products use various materials—including wood, rubber, metal, and thermoplastics—and designs to accomplish this task. The support systems generally fall into two categories: individual supports that hold single tubes, and multi clamps to secure two or more lines. Most systems can accommodate pipe and tube sizes from 3/16 to 24 in., while others handle sizes up to 42 in. Many will stack for several tiers, and they can be fastened down with a weld base or to a mounting rail.

Support Material

Although wooden blocks and rubber grommets are adequate for supporting pipes and tubing, they have several disadvantages. Wood tends to dry out, crack, and lose its absorption properties. Wood is also a relatively expensive support material. Aside from its lack of chemical and abrasive resistance properties, rubber is generally only used in conjunction with some kind of steel strap or surround, adding to the cost and complexity of these supports.

Hose vs. Tube: What’s the Best Call for Hydraulic Equipment?

What do lifting chains, bladder-type accumulators and hydraulic hoses all have in common? Well, they typically have only one mode of failure – and that’s catastrophic. One minute they’re working as they should, and the next thing you know, they’ve gone to hell.

Oh, sure, hoses can leak from around their ferrules and show obvious signs of abrasion, both of which are early warning signs that a change-out would be prudent. But even under these conditions, estimating their remaining service life is virtually impossible.

The Trouble with Hose

Beyond the fact that their service life is finite and difficult to estimate, other disadvantages of hydraulic hoses when compared to tubes include:

They expand and stretch under pressure. This flexing requires extra volume and adds to machine cycle time.
They typically have a limited operating temperature range.
Their requirement for regular replacement makes them a source of contaminant ingression.
They are expensive.
There is limited space (particularly in mobile hydraulics).
There is relative movement between machine components and superstructure.
Noise and vibration need to be suppressed.
Despite the above disadvantages, hoses are a necessary feature of most hydraulic systems. This is because the alternative conductor – tubes – cannot be used where:

There is limited space (particularly in mobile hydraulics).
There is relative movement between machine components and superstructure.
Noise and vibration need to be suppressed.
However, hose is often substituted for tube when it’s not necessary. This is because a hose assembly can usually be fabricated much faster than a tube assembly. And, the additional labor cost required to fabricate and install a tube can make hose appear to be the cheaper solution.

But this belies the fact that the same hose may need to be replaced many times over the life of the machine. This false economy is similar to buying the machine itself on initial capital outlay alone without considering its total life-of-ownership cost.

Tube is Cool

Hydraulic tubing has some compelling advantages of its own. One of these is its superior heat transfer, especially if it’s painted.

One aspect of heat transfer is thermal radiation. The total radiation from an object is the sum of its reflection, emissivity and transmission of heat through the object.

When hydraulic tubing is painted, it reduces its reflectance and increases its emissivity, enabling better heat rejection, as this case study published in Hydraulics and Pneumatics magazine1 illustrates:

An industrial hydraulic installation was originally designed to operate at 1,200 psi and at a maximum operating temperature of 120 degrees Fahrenheit (49 degrees Celsius). Zinc dichromate-coated steel tube distributes fluid from the 600-liter reservoir to the various stations around the plant. Over the years, the system had been added to (without any increase in installed cooling capacity)—to the point where it was now overheating in the summer months.
