Why Risk an HDPE Liner Collapse?
When vacuum conditions occur, loose HDPE liners can collapse on themselves – causing costly downtime on critical pipelines. Rubber and polyurethane linings are aggressively adhered to the pipe wall and do not collapse. The Joint Lock Ring™ system allows for welded joints with lined pipe, so the pipeline can be constructed just like a bare pipeline.
Collapsed HDPE pull-thru liner
HDPE pull-thru liner
- 15-20 year average design life for low abrasion applications.
- Significantly lower abrasion resistance.
- Not adhered to pipe wall; vacuum conditions or a hole in liner can collapse liner and plug pipeline.
- Slower construction as liners are pulled through pipe and high pressure flanges welded on.
- Gas permeation of HDPE liners require gas drainage outlets.
- Replacement of collapsed liner sections is time consuming.
- HDPE liners tend to lose tension as they age beyond 15 years. Potential for liner to sag into line of particle flow, wear thin, and collapse.

Polyurethane or Rubber-lined pipe with Joint Lock Ring™ welded joints
- More than 30 year design life for low abrasion applications.
- Excellent abrasion resistance – used worldwide for high wear applications.
- Excellent adhesion of lining to pipe wall which easily withstands vacuum condition.
- Pipeline is constructed like a normal bare pipeline.
- Easier and faster replacement of sections worn thin from abrasion.
- Low permeation rates: rubber & polyurethane formulated for low osmotic permeation.
