With many remarkable advantages of economic dispatch, progressively substitute traditional steel pipe at present, be widely used in the transportation art of pipe gas,
Polyethylene (PE) pipe applications are formally pressed into buried distributing system, buried polyethylene in combustion gas before and after 2000 in Shenzhen region
(PE) the inspection inspection major tasks in gas pipeline daily operation management are exactly to prevent third party's construction from being broken to caused by pipeline
It is bad, but simultaneously in running in recent years, a lot of polyethylene (PE) gas pipeline occur and corroded by termite and cause pipeline damage
The event of gas leakage is caused to occur, buried polyethylene (PE) gas pipeline termite is corroded with other pipeline damage forms not
Together, be generally not easy to find, it is typically found that when pipeline all occur perforation gas leakage substantially, such event possesses disguise, gives pipeline fortune
Battalion's unit and user bring very big economic loss, and contact burning things which may cause a fire disaster can cause during inflammable, explosive gas leakage such as to fail in time
It was found that and disposal, easily produce the serious consequence such as fire and blast, serious economic loss and huge caused to gas enterprise
Reputation influences.
