Industrial hoses has different types of inner wall
Proper hose installation is crucial. A hose that’s too long not only looks untidy but also drives up costs. On the other hand, if it’s too short, it won’t have enough space to expand and contract as it stretches or compresses under pressure, which can lead to damage. In fact, most hose failures stem from improper installation of the hose assembly.
In many cases, hose assemblies endure unacceptable torsional stresses. Additionally, bending the hose beyond the specified radius and wear that corrodes the reinforcement are common causes of failure. So, how can you install the hose assembly correctly? Here are some key tips:
Avoid Distortion
Never twist the hose, as a twisted hose has a significantly shorter lifespan. Twisted hoses are also more likely to get damaged or develop loose connections under pressure. According to relevant tests, even a 7-degree twist can reduce a hose’s service life by 80%.
Leave Allowance for Straight Pipes
When installing straight pipes, always leave some slack. This ensures the hose won’t tighten up or break when it moves under pressure. Since hoses expand and contract with pressure changes, you should reserve a margin of about 3% to 5%.
Clamp on Straight Segments
When hydraulic pressure jets through the hose, the pressure on the inside and outside of a bend becomes unbalanced, causing the hose length to change. For this reason, don’t place pipe clamps at elbows; instead, let the hose move freely at these points.
Adhere to the Bending Radius
A bending radius that’s too small will tear the reinforced steel wire braid on the outside of the hose bend, shortening its service life. Always make sure to meet the specified bending radius requirements.
