Epoxy coal asphalt anticorrosive spiral steel pipe

Description: The epoxy coal tar spiral steel pipe is commonly referred to as a few cloths and several oils, commonly including one cloth and two oils, three cloths and two oils, five steps and three oils, and seven cloths and four oils. The components of epoxy coal tar pitch spiral steel pipe are epoxy coal tar pitch primer and topcoat, both of which are mainly film-forming substances of epoxy resin and coal tar pitch, and are made by adding various anti rust pigments, insulation fillers, toughening agents, leveling agents, diluents, anti settling agents, etc. Appearance: Primer component A is iron red, component B is black, and the topcoat is all black.

Epoxy coal tar pitch spiral steel pipes have excellent resistance to chemical corrosion and good physical and mechanical properties, good adhesion, tough coating, excellent electrical insulation and penetration resistance, resistance to stray currents and microbial erosion. After film formation, the number of construction passes can be reduced.

The main execution standards for epoxy coal asphalt spiral steel pipes are SY/T 0447-96 Technical Standard for Epoxy Coal Asphalt Coating on Buried Steel Pipelines and SY/T 0457-2000 Technical Standard for Liquid Epoxy Coating Inner Layer of Steel Pipelines.
