Spiral pipe manufacturer for upgrading and renovating sewage treatment plants with a diameter of 529

Description :

　　 Our company has four advanced double-sided submerged arc welded spiral steel pipe production lines, which can produce double-sided submerged arc welded spiral steel pipes with diameters of 219-2420mm and thick walls of 5-30mm. Annual production of 100000 tons of spiral steel pipes.Materials Q235A, Q235B, 10 #, 20 #, Q345 (16Mn), etc.

　　Spiral pipe (SY/T5037-2000-GB/T9711.1-1997- API 5L), also known as spiral steel pipe or spiral welded pipe, is made by rolling low-carbon structural steel or low-alloy structural steel strip into a pipe blank at a certain angle of the spiral line (called forming angle), and then welding the pipe seam together. It can produce large-diameter steel pipes with narrower strip steel. Spiral tubes are mainly used in water engineering, petrochemical industry, chemical industry, power industry, agricultural irrigation, and urban construction, and are one of the twenty key products developed in China. Used for liquid transportation: water supply, drainage, sewage treatment engineering, mud transportation, ocean water transportation. Used for gas transportation: coal gas, steam, liquefied petroleum gas. Used for structural purposes: as pile driving pipes, as bridges; Pipes for docks, roads, building structures, marine pile driving pipes, etc.

　　The company uses spiral steel pipes, straight seam steel pipes, and seamless steel pipes as substrates for anti-corrosion processing. The types of anti-corrosion processing for steel pipes include:

　　1. Petroleum and natural gas use three-layer polyethylene (3PE) steel pipes for corrosion prevention, and two-layer polyethylene (2PE) steel pipes for corrosion prevention. Standard: SY/T0413-2002DIN30670;

　　2. FBE (single-layer fusion bonded epoxy powder anti-corrosion) steel pipes and 2FBE (double-layer fusion bonded epoxy powder anti-corrosion) steel pipes are used for oil and gas. Standard SY/T0315-97;

　　3. Anti corrosion measures for cement mortar lined steel pipes in water supply pipelines. Standard CECS10:89;

　　4. Epoxy coal tar glass cloth steel pipe for corrosion prevention. Standard: GB50268-97, SY/T0447-96; 5. Water supply pipeline IPN8710.

　　The following are our company's three oil two cloth external anti-corrosion steel pipes, H87 series and epoxy series anti-corrosion steel pipes.
