Tips for Identifying HDPE Pipe Quality


HDPE pipe is a flexible plastic pipe used for carrying liquid, gas and in the replacement of cement or steel pipes. The quality of HDPE pipes depends upon the raw products, processing machinery, and technology.


Important Tips for knowing HDPE Pipe Quality •

Feature: The inner and outer surface of good quality HDPE pipes is smooth without any faults like dents, bubbles impurities etc. But in low-quality pipes, the surface is not plane and bright. Refining Strips: In high-quality pipes, the refining strips are shiny, straight, and no break with frequent folding. But in low-quality pipes, the refining strips look dimmer, easily damaged by frequent folding. Connecting Joint: In high-quality pipes, welding joints have a plane and balanced turn-ups around the pipe circles and the turn-ups will be a bit lengthier after the pressure from fusion bonding. In low-quality pipes, there are lots of upset holes at the welding surface and the turn-ups will be smaller after the pressure from fusion bonding. Break Extending: Good quality pipes have superior break prolongation and the enhanced elasticity, and good performances.
