Description
Technical field
The present invention relates to the making field of plastic tube, more precisely, being a kind of buried feed pipe modified poly ethylene.
Background technology
Study and improve all the time for the polythene material applied to tubing in the world, exactly because material
Can update, the especially appearance of PE100 pipes substantially increases the allowable stress of polyethylene pipe, can use pressure same
Wall thickness is reduced under power, increase conveying section, while enhancing the ability of resistance Crack Extension, further enhancing polyethylene pipe
Advantage.The material of polyethylene pipe is divided into five grades of PE32, PE40, PE63, PE80, PE100 in the world at present, and is used for
The material of Gas Pipe and feed pipe is mainly PE80 and PE100.China is not classified to Polyethylene Pipe Resin, and this causes
Domestic polyethylene gas pipe and feed pipe manufacturer selection raw material are relatively difficult, and the also use to polyvinyl piping materials is brought
No small hidden danger.Therefore State Standard Bureau has made substantial amounts of revision in GB/T13663-2000 new standards, defines feedwater
The different stage PE80 different intensities of pressure corresponding with PE100 of pipe, and remove the tensile strength performance in old plant, and increase
Add elongation at break, that is, emphasize basic toughness.
The buried feed pipe that polythene material is made its mechanical property under normal temperature condition is relatively stable, corrosion resistance
It is more outstanding.The toughness of body drastically declines when underground pipe is used for extremely cold area, the easy embrittlement of tubing, and service life shows
Write and shorten.
