Spiral Steel Pipe Manufacturer
Spiral welded pipe: It is made by rolling low-carbon carbon structural steel or low-alloy structural steel strip into a pipe blank at a certain spiral angle (called forming angle), and then welding the pipe seams. It can be made of narrower pipes. Strip steel produces large diameter steel pipes.

Spiral steel pipe is a commonly used steel material in industries such as industry and construction. It is a spiral seam steel pipe made of strip steel coil as raw material, often formed by warm extrusion, and welded by automatic double wire double-sided submerged arc welding process. Mainly used in water engineering, petrochemical industry, chemical industry, power industry, agricultural irrigation, and urban construction.
Spiral steel pipes are used for liquid transportation: water supply and drainage. 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, etc. It has played a significant role in transporting gas and transportation.
Spiral seam submerged arc welded steel pipes for pressurized fluid transportation are mainly used for pipelines transporting oil and natural gas; Spiral seam high-frequency welded steel pipes for pressurized fluid transportation, welded by high-frequency lap welding method, used for spiral seam high-frequency welded steel pipes for pressurized fluid transportation. Steel pipes have strong pressure bearing capacity, good plasticity, and are easy to weld and process into shapes; Spiral seam submerged arc welded steel pipes for general low-pressure fluid transportation are made using double-sided automatic submerged arc welding or single-sided welding methods, and are used for general low-pressure fluid transportation such as water, gas, air, and steam.
