Introduction to the excellent performance of drinking water anti-corrosion steel pipe


the use of plastic-coated steel pipes in developed countries has been relatively mature. for example, in the water pipes in the united states, japan, and other countries, 80% to 90% of the pipes are plastic-coated steel pipes. the coated steel composite pipe meets the construction water supply and drainage requirements and fully companies with cj/t120-2008 and gb/t5750-2006 standards and has been highly praised and affirmed by customers in recent years.

ipn8710 non-toxic drinking water anti-corrosion steel pipe should be painted with topcoat within 16 hours after anti-rust treatment, and within 8 hours in humid and cold areas and coastal cities, otherwise, it will cause secondary corrosion and must be cleaned with a wire brush.

rust removal method for ipn8710 anti-corrosion steel pipe: clean the welding position of ipn8710 anti-corrosion steel pipe that has been pre-coated with workshop topcoat during transportation and assembly, the damaged position and defects caused by heat treatment, and the damaged position caused by hot work with an electric grinding wheel and wire brush; for the white rust (zinc salt) coated with zinc powder topcoat and corroded by air, clean it with a manual or electric wire brush and clean water; for ipn8710 anti-corrosion steel pipe with high hardness two-component curing coating, the paint layer must be roughened chemical and clean with sandpaper and wire brush.

long-distance waterproof steel pipes will be corroded by various environmental media, among which electrochemical corrosion and biological corrosion are the main corrosion factors.

steel-plastic composite pipes and ductile iron pipes are recommended for large-diameter water delivery system projects, but steel-plastic composite pipes are more cost-effective. the steel pipe has good ductility, complete structure, and convenient construction. it is not only suitable for laying on the ground but also suitable for the construction operations of the overhead river crossing, pouring, and pipe jacking.

using anti-corrosion coatings to protect the inner and outer wall surfaces of steel pipes and fittings is a more convenient and commonly used protection technology. the steel-plastic composite pipe after inner and outer protection is cost-effective. it is a combination of the excellent properties of steel pipe and plastic pipe, with the strength and rigidity of steel pipe, chemical corrosion resistance of plastic, smooth inner wall, no scaling, and small fluid resistance.

long-distance water delivery anti-corrosion steel pipe technology is a long-term anti-corrosion treatment technology in my country at present. it combines steel and superior mechanical system properties with the chemical corrosion resistance of polymer composite materials, prolongs the service life of steel pipes, and has a certain anti-corrosion, acid and alkali resistance, wear resistance, non-scaling, auxiliary lubrication method, negative pressure resistance, and other unique advantages can replace plastic-lined pipes, galvanized pipes, stainless steel pipes, copper pipes, etc.

the polymer anti-corrosion powder coating can be evenly coated on the inner and outer surfaces of the metal pipe by using special equipment, and after curing and plasticizing, a uniform, dense, and smooth plastic coating is formed on the inner and outer surfaces of the metal pipe, becoming a new type of steel-plastic composite pipe. anti-corrosion steel pipes for long-distance water transportation can effectively prevent secondary environmental pollution of water quality, and the effect of improving water quality management is obvious.
