Price of epoxy coal tar anti-corrosion steel pipes for sewage discharge

Description :

　　When there are many types of corrosive media inside the steel pipe, such as acid, alkali, salt, oxidant, and water vapor, the coating must have chemical inertness, acid, alkali, and salt corrosion resistance. The coating should have a dense structure, good waterproof penetration, strong adhesion, toughness, and fullness. This type of situation applies to IPN8710 anti-corrosion.

　　IPN8710 anti-corrosion primer: composed of polyurethane polyethylene, modified epoxy resin, non-toxic anti rust pigments and fillers, additives, etc., it solidifies at room temperature to form an interpenetrating network. The coating structure is dense, acid, alkali, and salt resistant, with excellent anti rust performance and strong adhesion. It is used for anti-corrosion primer coating on the inner wall of water supply pipelines. IPN8710 anti-corrosion topcoat: composed of epoxy, rubber resin modification, non-toxic anti rust pigments and fillers, additives, etc. Excellent chemical resistance, non-toxic, and resistant to microbial erosion, used as an anti-corrosion coating for the inner wall of water supply pipelines.

　　The excavation volume of soil and stone in the corresponding pipeline trench, temporary land occupation, pipe fitting size, and occupation have all been reduced accordingly. After comprehensive consideration of cost-effectiveness and construction difficulty, TPEP steel pipes (external 3PE internal fusion bonded epoxy steel pipes) are selected for water supply units with a diameter greater than DN800, and TPEP anti-corrosion straight seam steel pipes are used for tap water to provide more detailed understanding. They are mainly made of epoxy resin and coal tar pitch as film-forming materials, with various anti rust pigments, insulating fillers, toughening agents, leveling agents, diluents, anti settling agents, etc. The B component is a modified amine curing agent or a curing agent as the main material, with added pigments and fillers. When this product is sold, A and B components are supplied together and mixed in proportion during construction.
