Spiral Steel Pipe

Spiral steel pipe is a kind of steel widely used in industry, construction and other industries at present. Spiral steel pipe takes strip steel coil as raw material, often warm extrusion molding, and is formed by automatic double-wire double-sided submerged arc welding process. Widely used in water conservancy, natural gas, oil, heating, piling and other industries of basic engineering. Our company produces steel pipe diameter in DN300-DN3600, steel pipe wall thickness 5-26mm. The steel pipe materials that can be met include: Q235, Q355, API Spec5L, X42-X70, etc.
Each of our steel pipes will undergo three tests, namely X-ray test, hydraulic test and ultrasonic test, to ensure that the quality of each steel pipe is qualified.
Each of our steel pipes has its own identity code to ensure the stability of quality.
We use the most advanced Lincoln welding machine, which is the most advanced welding machine at present, in addition to each of our processes to achieve the ultimate, will meet the implementation standards, we will be on both sides of the coil milling process, the use of anti-corrosion layer welding wire, to ensure the quality of the weld; Both ends of our steel pipe have been prepared with bevels, which can be welded directly at the project site.
Our steel pipe production in strict accordance with the norms, raw materials are with China’s steel factory cooperation, our products are trustworthy.
