Large diameter coated steel pipe
Coated steel pipe is made by coating plastic based on large-diameter spiral welded pipe and high-frequency welded pipe. The maximum pipe diameter is 1200mm. Polyvinyl chloride (PVC), polyethylene (PE), epoxy can be coated according to different needs. Plastic coatings with various properties such as a resin (EPOZY), good adhesion, strong corrosion-resistance, resistant to strong acids, strong alkalis and other chemical corrosion, non-toxic, non-corrosive, wear-resistant, impact-resistant, and strong in permeability, The surface of the pipeline is smooth and does not adhere to any material, which can reduce the resistance during transportation, increase the flow rate and transportation efficiency, and reduce the pressure loss of transportation. There is no solvent in the coating, no exudate substances, so it will not pollute the conveyed medium, to ensure the purity and sanitation of the fluid. It can be used alternately with cold and hot cycles in the range of -40℃ to +80℃ without aging It does not crack, so it can be used in harsh environments such as cold regions. Large-caliber coated steel pipes are widely used in engineering fields such as tap water, natural gas, petroleum, chemicals, medicine, communications, electric power, and oceans.
