高密度聚乙烯（HDPE）管材，是采用高密度聚乙烯樹脂經(jīng)擠出機(jī)擠出而成，產(chǎn)品抗老化，強(qiáng)度高，耐磨性能好。同時(shí)具有優(yōu)異的耐腐蝕、耐沖擊、耐低溫、自潤滑、流阻小等性能，適用于供水、制藥、化工、排污、沙漿等腐蝕性介質(zhì)的輸送及高層建筑的雨水管等。規(guī)格與FRPP管相同，使用溫度-20℃- 70℃。（執(zhí)行GB/T136HDPE pipe materials use HDPE resin are made by high pressing. The products have many traits such as resistance ageing, high strength, good resistance to abrasion. As well as this trait, the pipe materials have some excellent comprehensive traits such as resistance to corrosion impact and low temperautre, self-lubrication, small flowing. The products can be used to transport such as supply water, pharmacy, chemical industry, metallurgy and sewage disposal, some corrosive mediums. such as mortar etc. and can be used to high construction water pipes. The specifications of HDPE pipe materials are the same as FRPP. The using tempatrue are -20℃ to 70℃.標(biāo)準(zhǔn)）
