plastic-coated steel pipe for water supply is a new type of composite pipe specially developed for water supply and drainage. the composite pipe combines the characteristics of various pipes. it is a green and energy-saving pipe with very high-cost performance due to its small co

the inner and outer plastic-coated epoxy resin steel pipes are suitable for water supply and drainage, drinking water, clean water, seawater, warm water, oil, gas, and other media transportation. the inner and outer surfaces of the steel pipe or only the outer surface can be coat

coated steel pipe requirementsthe coating layer should be smooth and flat, free from scratches, cracks, pinholes, and adhesion of foreign matter and other defects. the outer coating of the steel pipe shall be red. there should be a clear and durable mark on the coated steel p

both plastic-coated steel pipes and coated steel pipes are coated steel pipes, but their coating methods are different. plastic-coated steel pipes are coated with molten plastic on the surface of steel pipes to form a uniform plastic coating. this coating has good corrosion resis

1. weld seam defects: weld seam defects are serious, and manual mechanical grinding is used to make up for them. the resulting grinding marks will cause uneven surfaces and affect the appearance. pickling and passivating only the weld seam also creates an uneven surface.

30 years anniversary activity in bestar steel.here is the first part in beijing.

plastic-coated steel pipe is suitable for the working environment of -30°c-120°c. compared with other metal pipes, plastic pipes, and composite pipes, it combines the characteristics of various pipes. it has both the strength of steel pipes and the corrosion resistance of plastic

epoxy resin-coated steel pipes inside and outside first pre-treat the base pipe--grind the steel pipe (advantages: automatic spraying makes the inner and outer walls of the base material evenly coated, and the leveling property is good. it meets the cj/t120-2008 standard and gb/t

as we all know, plastic-coated steel pipes can be used not only in the field of water supply and drainage but also in the field of automatic sprinkler fire extinguishing systems, groundwater sewage dredging pipes, central air-conditioning cooling circulating water pipes, cable th

plastic-coated steel pipe is a new type of pipeline material recently developed in china. it adopts a composite structure with a plastic-coated protective layer inside and outside, and a reinforced welded steel pipe or seamless pressure-bearing steel pipe in the middle, which ove

plastic-coated steel pipes, also known as plastic-coated pipes, steel-plastic composite pipes, and plastic-coated composite steel pipes, use steel pipes as the substrate and weld a layer of plastic anti-corrosion layer or steel-plastic composite steel pipe with plastic anti-corro
