HDPE PIPE BUTT FUSION METHOD

HDPE pressure piping system use butt fusion to connect for big size, socket fusion for small size

Butt fusion is using welding machine to heat pipe at both ends ( the temperature is 210 + - 10℃)until the pipe end melted, it should adhesion the HDPE pipe end rapidly and keep a certain pressure, after cooling, all the procedures have been finished, the following table is the reference for the welding procedures.

ZHSU HDPE gas pipes are mainly used in oil and gas gathering systems for gas and oil transmission and distribution,underground & submarine gas pipeline,ventilation tubes in coal mines, road、railway and tunnel ventilation system, methane drainage pipelines etc.
ZHSU HDPE PIPE WORKSHOP
In order to cooperate with national and international rural drinking water safety project, ZHSU adopted large diameter facility for PE production, our biggest PE pipe diameter reached DN1200mm at present, ZHSU has become one of the manufacturers in china who can produce such large diameter PE pipe.
ZHSU CNAS NATIONAL LABORATORY
ZHSU has CNAS proved national laboratory, 100% imported Borealis or South Korea raw material for HDPE pipes, full sets of inspections will be made by zhsu national laboratory for each order during and after production procedure, meanwhile CNAS inspection report will be provided and traceable.
High quality assurance for green and healthy pipes, we cherish every drop of water as it’s our social responsibility and mission
