Hydraulic hoses must be durable and long-lasting enough to handle the needs of the particular function. Hydraulic hoses, unlike many other industrial hoses, need substantial reinforcement to endure the significant pressures that are necessary to perform their job. Reinforcing support can come in many forms depending on the levels of pressure, materials, and other factors that the hose will be required to withstand.
Consider STAMPED When Selecting Hydraulic Hoses
When determining which hydraulic hoses and fittings will be right for your situation, TCH Industries of Twinsburg, Ohio, suggests considering the acronym “STAMPED.” Seven questions cued by each letter will help identify which hydraulic hose is right for your situation. These are:
- S: Size and diameter of the hose. Not only does this refer to the internal diameter of the hose but also to the required length from port to port.
- T: Temperature refers to the maximum and minimum temperatures that the hose will withstand during all parts of the process.
- A: Applications refers to the actual use of the hose and equipment. Will this be for industrial use or injection molding, for example.
- M: Media refers to the liquid, gas, or solid that will be conveyed. Different medias require different levels of strength to accommodate what will be moving within.
- P: Pressure is a critical variable in hydraulics. Pressure is the force that moves and lifts, so factoring the degree of pressure that the hose will need to withstand is essential.
- E: Ends of the hose will be determined by where the hose will connect. The origination and destination ports may be different so the assembly might require different connecting hardware.
- D: Delivery dates may be requested. These may depend on testing, certification requirements and, perhaps, custom production times.
Dealing with High Pressure
Hydraulic hoses, more than any other, are expected to withstand higher-than-normal pressure while in full operation. As a result, added reinforcement becomes mandatory.
The type and degree of reinforcement are calculated by the working pressure of the hydraulic system. As the pressure increases, the PSI rating of the hose must increase as well.
Most hydraulic hose reinforcement material may be one of three types, although combinations of these are often used to bolster the pressure capacity. These materials are:
- Braided synthetic textiles, wire, and other materials set in a crisscross, overlapping pattern that allows for flexibility and maximum strength.
- Spiral Wrapping with wire, textiles, synthetic materials consisting of parallel, rather than overlapping reinforcement. This pattern strengthens the hose while allowing for lower flexibility.
- Helical coil (a helix pattern) strengthens the hose to prevent it from collapsing inside when suction or a vacuum is applied. The coil is often used in conjunction with the braided textile reinforcement to manage both high and low-pressure situations.
