How to Control Hose Quality : Conventional testing of PE Corrugated Hose Air Tightness | PASSIONHOSE Quality Control

Conventional testing of Hose Air Tightness includes pneumatic testing and water pressure testing.

Pneumatic testing equipment is generally made for hard pipe detection, 

no corresponding testing equipment for corrugated hose and other flexible pipes.

Corrugated hose is generally chosen the water pressure detection.

The specific how-to:

1. Seal the ends of the corrugated hose

2. Pressurize and place the hose in the water

3. Check the airtightness, according to the presence of bubbles to determine whether the hose leakage

4. If bubbles are generated: airtightness test fail→destroy the hose

    If no bubbles: airtightness test pass→qualified hose

In the video, our QC colleague is inserting the two ends of a roll of corrugated hose into the interface of the testing equipment. 

She will set the testing parameters to see if the hose will bubble. 

Bubbling means water leakage and the airtightness test fails.

We are glad that we haven't detected any corrugated hose that failed the air tightness test so far.
