What are the reasons for high pressure hose damage?

Visit:   Release time: 2015-3-15 15:36:11
High pressure hose wall inner and outer layers are built by rubber, in the middle (2-4 layers) cross woven wire or winding wire.Most of the high pressure hoses are built by standard, so the qualified products' structure will be similar.
If damaged during the guarantee period, the reasons will be one or more of the below:
*Poor quality:
       The inner or outer layer rubber is too thin
       Uneven wall thickness
       Steel wire braided too tight, too loose or too few layers of steel wire
*Not correct installation:
       1. Avoid twist: if the hose is twisted frequently, it will shorten the life of the hose(bend 30degree will decrease 90% of the hose life), and the couplings are easy loosen.

Correct

 
     2.Not bend less than the bending radius:if the hose assembly was bend 20% less then the bending radius, it will decrease 90% of the hose life. By the way, too small bending angle will damage the pipe and hinder the liquid flow.So we need to keep enough bending angle when install the hose.

Correct
 


 
     3.Use bend and connectors if necessary:bend and connectors will help you to avoid too long pipe line and also can make the lines tidy and easy to repair.

Correct
 
      4.Keep the hose loosely enough:when working in pressure the hose will have a elongation rate of -4% to 2%, so we need to keep the hose loosely enough to compensate the elongation.
 
 


 
 
 
 
      5.Use pipe clamp to fix:use the clamp not only can fix the hose accessory but also can avoid the abrasion between the next parts.

Correct

 
      
     6.Reasonable arrangement:when arrange the pipe lines,avoid the hose touch the surface of the hot parts and the edge of sharp objects, keep the hose from rubbing against other parts,leave enough length for bending movements.

Correct
