Inner wall: centrifugal mechanical spraying cement mortar, LPN8710 polymer non-toxic coating, epoxy water dispenser pipeline equipment non-toxic coating.
Spiral steel pipe, also known as spiral pipe or spiral welded pipe, is made by rolling low-carbon structural steel or low-alloy structural steel strip into a tube blank at a certain spiral angle (called forming angle), and then welding the tube seam. It can produce large-diameter steel pipes with narrower strip steel.
The commonly used standards for spiral steel pipes are generally divided into: SY/T5037-2008 (Ministry Standard, also called spiral seam submerged arc welded steel pipe for ordinary fluid transportation pipelines). GB/T9711.1-2008 (National Standard, also called the first part of the delivery technical conditions for oil and gas industry transportation steel pipes: Grade A steel pipe (GB/T9711.2B grade steel pipes with strict requirements), API-5L (American Petroleum Institute, also called pipeline steel pipes, which are divided into two levels, PSL1 and PSL2), SY/T5040-2008 (spiral welded steel pipes for piles).
Spiral steel pipes are mainly used in tap water projects, petrochemical industry, chemical industry, power industry, agricultural irrigation, and urban construction. They are one of the 20 key products developed in my country.
Liquid transportation: water supply and drainage. Gas transportation: coal gas, steam, liquefied petroleum gas. Structural use: pile driving pipes, pipes for bridges, docks, roads, and building structures.
