Why flexible hoses fail

Piping systems

There are many reasons why flexible hoses fail. It can be a frustrating and costly experience and can result in manufacturing downtime that costs your business thousands, if not millions of dollars. 

Hose assemblies and flexible hose connections are often the least monitored and regulated manufacturing component. They are plagued by expectations that they should continue to operate under a wide variety of physical stresses, no matter the conditions. 

Like all other components of manufacturing systems, flexible hose connections are prone to failure. Regular, comprehensive inspections are essential to prolong the life expectancy and durability of your hoses and connections. 

As a third generation Australian owned and operated business, the experienced team at Pacific Hoseflex have encountered the many different ways flexible hoses can fail. 

Reasons for flexible hose failure: 

1. Design failure

2. Installation failure

3. Failure due to incorrect use

4. Failure due to improper maintenance or storage.

Design failure

  • Movement beyond capabilities of hose connection.
  • Abrasion to flexible hose cover.
  • Installation beyond design.
  • Hose reels.

Installation failure

  • Horizontal hook-ups.
  • Stress caused by bending.
  • Directly clamping to the pipe.
