Buried preservative or preservative 3pe strengthen the level improve corrosion pipeline life

Corrosion, also known as anti-corrosion steel pipe is generally refers to the embalmed processing technology, can effectively prevent or slow down the steel pipe occurred in the transport and use of chemical or electrochemical reactions of corrosion phenomena. According to our statistics, the annual domestic steel corrosion in direct economic losses of more than 2800 billion in current annual global losses due to pipe corrosion up to $ 500 billion. Corrosion pipe can effectively prevent or slow down corrosion. Edit this paragraph corrosion within the steel pipe classification when more types of corrosive media, such as acid, alkali, salt, oxidants and water vapor, etc., the coating must be chemically inert, acid salt corrosion, the coating should be compact structure, water infiltration good, strong adhesion, tough fullness. Such applies IPN8710 corrosion. IPN8710 anticorrosion primer: from polyurethane, polyethylene, modified epoxy resin, non-toxic anti-rust pigments, additives and other components, room temperature curing form an interpenetrating network, a dense film structure, acid and alkali, salt, rust excellent performance, strong adhesion for water supply pipeline wall corrosion primer coating. IPN8710 anticorrosive finish: epoxy, rubber resin-modified, non-toxic anti-rust pigments, additives and other components. Excellent chemical resistance, non-toxic, anti-microbial erosion, corrosion for water supply pipeline wall finish. FBE epoxy powder preservative FBE epoxy powder preservative structure: electrostatic spraying epoxy powder coated steel pipe surface, a film. The coating has a coating operation is simple, clean, good coating impact resistance and flexural properties, temperature resistance advantages. 2PE / 3PE preservative 2PE / 3PE antisepsis structure: the steel surface electrostatic spraying epoxy powder and lateral wound adhesive, lateral wound polyethylene coating, with three excellent performance, which significantly improves the overall quality pipeline corrosion . Resistant to chemical corrosion, cathodic stripping, resistance to mechanical damage performance. Coal tar epoxy coal tar epoxy structure: from coal tar pitch + epoxy + filler made of anti-corrosion coating on the pipe surface with a glass cloth as a reinforcement formed by coating the coating, commonly used in the pipe wall corrosion. Thickness of 0.5 ~ 1.0mm. High-density polyethylene high density polyethylene jacket coat anticorrosive anticorrosive structure: the outer surface of the steel pipe wrapped high density polyethylene material with high mechanical strength and excellent corrosion resistance, can protect steel during transport, installation and use of the process to avoid damage due to external factors caused. Manufacturing outer casing should be added antioxidants, UV stabilizers, and carbon black. Polyethylene outer tube easy to aging, such as open storage and other objects appropriate to tarp covered dumps should be kept away from heat and ignition sources, made after anti-corrosion steel, prohibit exposure, quenched, or polyethylene outer tube easy to crack, the impact of product performance and service life. Edit corrosion standard FBE epoxy powder preservative in this paragraph perform SY / T0315-1997 "steel pipeline FBE external coating technology standards" 2PE / 3PE preservative execution SY / T0413-2002 "buried steel pipeline polyethylene outer coating technology standards "anti-corrosion surface rust criteria: by sand-blasting the outer surface of the steel pipe GB / T8923-1988 requirements of Sa2 1/2 grade steel anchor profile of the surface of 40-100μm. Edit this paragraph uses corrosion pipe mainly used in domestic pipeline projects in petroleum, chemical, natural gas, heat, sewage treatment, water, bridges, steel and so on.
