The materials of SSAW steel pipes are Q235B, Q345B, etc.
SSAW steel pipe is spiral submerged arc welded steel pipe. It is a spiral seam steel pipe welded by automatic double-wire double-sided submerged arc welding process. Strict physical and chemical inspections are required before being put into use. Single-wire or double-wire submerged arc welding is used for the head-to-tail docking of the strips. Automatic submerged arc welding is used for repair welding after being rolled into steel pipes. All completed welds are inspected by an online continuous ultrasonic automatic flaw detector, ensuring 100% non-destructive testing coverage of spiral welds.
Spiral submerged arc welded steel pipe
1. Types and characteristics of spiral submerged arc welded steel pipes of different specifications
Spiral submerged arc welded pipes can be divided into many types according to material, production process, specifications and sizes. Common types include: carbon steel spiral pipe, stainless steel pipe, alloy steel pipe, galvanized spiral pipe, etc. Spiral pipes of different specifications have different sizes, wall thicknesses, weights, etc., so they have different characteristics and application ranges.
2. Comparison of uses of SSAW steel pipes of different materials
Carbon steel spiral submerged arc welded steel pipe: mainly used to transport water, gas, liquid and other media, widely used in construction, chemical industry, petroleum and other fields. Its advantages are good corrosion resistance, long service life and relatively low price.
Stainless steel pipe: mainly used to transport corrosive media, such as acid, alkali, salt, etc. Its advantages are good corrosion resistance, beautiful appearance, and suitable for various occasions.
Alloy steel pipe: It has the characteristics of high strength and corrosion resistance. Mainly used in high-pressure, high-temperature, high-strength medium transportation fields such as chemical industry, petroleum, and nuclear power.
Galvanized spiral submerged arc welded steel pipe: mainly used to transport gas, liquid and other media, especially suitable for occasions requiring anti-corrosion. Its advantages are good anti-corrosion performance and long service life.
