TPEP anti-corrosion steel pipe (i.e. outer 3PE inner EP anti-corrosion steel pipe) is an upgraded product based on outer polyethylene inner fusion bonded epoxy composite steel pipe, and is currently a more suitable anti-corrosion form for buried long-distance pipelines. The outer wall of TPEP anti-corrosion steel pipe adopts a hot melt wrapping process, with a bottom layer of epoxy resin, an intermediate layer of adhesive, and an outer layer of polyethylene forming a three-layer structure of anti-corrosion layer. The inner wall adopts a hot spray epoxy powder anti-corrosion method

TPEP防腐钢管(即外3PE内EP防腐钢管)是在外聚乙烯内熔结环氧复合钢管的基础上升级换代产品,是目前埋地长输管线较为适合的防腐形式。TPEP防腐钢管外壁采用热熔结缠绕工艺底层环氧树脂,中间层胶黏剂,外层聚乙烯形成三层结构的防腐层,内壁采用热喷涂环氧粉末防腐方式,将粉末经高温加热熔结后均匀地涂敷在管体表面上。TPEP防腐钢管是长距离中大口径的输水管道供水系统的关键环节。
