3EP Coated Steel Tube
3EP coated steel tube Generally used in municipal and major building water supply and drainage above, it is the outer wall coating high adhesion, impact resistance, anti-corrosion weather-resistant thermosetting powder coating, inner wall coating high adhesion, anti-corrosion thermoplastic powder coating.It is made by sandblasting chemical double pretreatment, preheating, internal coating, external coating, solidification, post-treatment and other processes.Besmear steel tube wall bright and clean, good drainage performance, fluid resistance is small, not fouling is compared with other pipe advantages, can greatly reduce the loss.In the meantime, the linear expansion coefficient of besmear model tube is very small, this makes its as main trunk conduit very advantageous, overcame the blemish with big linear expansion coefficient of other plastics and common pipe material greatly.Large diameter coated steel pipe is the traditional steel and plastic pipe, galvanized pipe upgrade type of high cost performance products.It has comprehensive characteristics, namely steel pipe high strength, high extensibility, low temperature brittleness, small expansion coefficient, and plastic pipe corrosion resistance, wear resistance, fluid resistance, small and other advantages, belongs to a new water supply and drainage, anticorrosive green large diameter pipe, by the domestic industry more and more widely used.The fire service plastic-coated composite pipe is used in the hot water pipe, and it is necessary to prepare the polyethylene lining in advance.When using sealant, it is necessary to apply heat-resistant rubber for sealing. Hot water cannot be directly used in cold water pipes and fittings.
