Coated steel pipe is the pipe based as the matrix melt spray or adsorption food-grade epoxy powder coating or PE raw materials at high temperature curing from new materials, through a special process in the wall.
Coated steel pipe is with excellent corrosion resistance and frictional resistance. Epoxy coated steel pipes is used for water supply and drainage, sea water, warm water, oil, gas and other medium of transportation, and polyvinyl chloride (PVC) coated steel pipe is for drainage, sea water, oil, gas and other medium of transportation.
产品特点：钢管是PE（改性聚乙烯）热浸涂或EP（环氧树脂）产品内外涂层，具有优异的耐腐蚀性。涂层本身具有良好的电绝缘，不会产生电腐蚀。低吸水性，机械强度高，摩擦系数低，达到长期使用的目的。此外，有效地防止植物根系和土壤环境压力的破坏。
涂层钢管内外溶解层熔体在管壁厚度0.5〜1.0mm聚乙烯（PE）树脂，乙烯 - 丙烯酸共聚物（EAA），环氧（EP）粉末，无毒聚丙烯（PP）钢 -塑料复合管，或无毒的聚氯乙烯（PVC）等有机形式，它不仅具有钢管的高强度，易于连接，耐水抗冲击，还克服钢管水腐蚀，污染，缩放和塑料管的强度不高，防火性能较差的设计寿命长达50年。
The main disadvantage of not bending, thermal processing and welding cutting operation is to install the application manufacturer, the cut surface with some non-toxic room temperature curing adhesive brushing.
规范，标准和识别Welded steel pipe (steel pipe manufactured with a weld) is a tubular product made out of flat plates, known as skelp, that are formed, bent and prepared for welding.
Our team is highly trained and experienced in servicing and producing all types of steel supplies.
