压花聚乙烯涂层钢管是近年来新开发出来的一种涂层钢管。它主要用在海底管线,是一种重防蚀用性能优良的新产品。这种涂层钢管在聚乙烯涂层外表面上增加压花,其目的是与混凝土形成一体化,防止铺设管线时混凝土层脱落,损伤钢管表面。对压花聚乙烯涂层钢管做了附着力、压扁和弯曲等性能检验。并与无压花的聚乙烯做了对比,通常在不压花的聚乙烯表面上涂敷混凝 Embossed polyethylene coated steel pipe is newly developed in recent years, a coated steel pipe. It is mainly used in submarine pipeline, is a heavy anti-corrosion with excellent performance of new products. This kind of coated steel pipe adds embossing on the outer surface of polyethylene coating, the purpose of which is to integrate with the concrete to prevent the concrete layer from falling off during the laying of the pipeline and damaging the steel pipe surface. The embossed polyethylene coated steel pipe made of adhesion, flattening and bending performance testing. In contrast to non-embossed polyethylene, it is common to coat the non-embossed polyethylene surface with coagulation
