Abstract

DC60 (17/12/52) Steel pipe with conductive resin coating and extrusion method for steel pipe which Can use fillers instead of carbon black. And it not only reduces production costs, but also increases its attractiveness. Steel tube with resin coating Where the newly produced resins (3) such as polyethylene, ABS, AAS and the external surrounding surfaces of thin-walled steel pipes (2) are coated with polypropylene. And conductive resins (4) such as polyethylene, ABS, AAS and polypropylene. Which was mixed with the filler on the outer surrounding surface of the coated resin (3), axially homogeneous in cross-section by a double-coated structure where its (4b) section, which There is the wall thickness and width required to develop its electrical conductivity. Placed at one or more positions in the direction along the circumference of the pipe And all external surrounding surfaces It is coated with some resin.
