Using hose guides, supports and protectors

Technical explanation

Contact of the hose with sharp edges, hot surfaces and moving parts must be prevented. Additional protection is selected to suit the environmental and product conditions. A rigid or incorrectly positioned support can concentrate bending in a small area. Damage or moisture can become invisible under a sleeve; the inspection method is planned separately. Restraint devices against hose separation are also evaluated only with the relevant application and manufacturer requirements; not every protective sleeve performs the same function.

How to evaluate it in practice

First determine the type of hazard: rubbing, spray, radiant heat or impact. Then match suitable protection with manufacturer data. Design how the sleeve will be opened during maintenance and how the hose label will be read. Determine the support spacing from the hose weight, motion and manufacturer instructions instead of taking it from a universal number. After adding protection, repeat the full motion check; the protection must not create a new rubbing point.

Frequently asked questions

Does a spiral guard prevent all hose damage?

No. On its own it does not solve problems such as chemical degradation, wrong pressure, torsion or faulty assembly.
