National standard spiral steel pipe manufacturer

Manager Bi of Hebei Tianze Pipeline Co., Ltd. has a double-sided submerged arc welding spiral steel pipe production line, with an annual output of 10,000 tons of * spiral steel pipes, product implementation/standards and standards, and can produce spiral steel pipes of B steel grade with different wall thicknesses. Our company An investment of RMB 10,000 was invested in adding two new straight-seam steel pipe production lines, which can produce straight-seam steel pipes. The products are widely used in petrochemical, natural gas, hydropower plant, sewage treatment, bridge piling, steel structure pillars and other projects. Usage: water supply engineering, petrochemical industry, chemical industry, power industry, agricultural irrigation, urban construction, liquid transportation, water supply and drainage, gas transportation, gas vapor, liquefied petroleum gas, structure, pile driving, spiral steel pipe for piles, bridge steel structure, dock, road building structure, pipe, etc. The pipe is formed by bending hot-rolled strip steel in a spiral shape, and using submerged arc automatic welding to weld the inner and outer seams to form a spiral pipe. Spiral steel pipe uses Spiral steel pipes are mainly used in water supply engineering, petrochemical industry, chemical industry, electric power industry, agriculture, irrigation and urban construction. They are one of the twenty key products developed in our country. Water supply and drainage for liquid transportation. Gas vapor and liquefied petroleum gas are used for gas transportation. It is used as a piling pipe for structural purposes, as a pipe for bridges, docks, road construction structures, etc. Spiral seam submerged arc welded steel pipes for pressure-bearing fluid transportation are mainly used in pipelines for transporting oil and gas. Spiral seam high-frequency welded steel pipes for pressure-bearing fluid transportation are welded by high-frequency lap welding and are used for spiral seam transportation of pressure-bearing fluids. High frequency welded steel pipe.
Nowadays, the commonly used standards for spiral steel pipes are generally divided into/partial standards, also called spiral seam submerged arc welded steel pipes for ordinary fluid transportation pipelines. National standards are also called oil and gas industry transportation steel pipes. Delivery technical conditions, first-class steel pipes, to the current strict requirements. There are BB grade steel pipes American Petroleum Institute also called pipeline steel pipes which are divided into two grades/piles and spiral welded steel pipes. / is a standard set by the Ministry of Petroleum, generally called Ministry Standard B and National Standard Spiral Pipe. It is a steel pipe for transportation in the oil and gas industry. It is a spiral seam high-frequency welded steel pipe for general low-pressure fluid transportation. It is made of hot-rolled steel strip coils and is often spirally formed at high temperature. , using high-frequency lap welding method to weld spiral seam high-frequency welded steel pipes for general low-pressure fluid transportation. Spiral welded steel pipes for piles are made of hot-rolled steel strip coils as tube blanks, which are often heated and spirally formed, and are made by double-sided submerged arc welding or high-frequency welding. They are used for steel pipes for foundation piles such as civil construction structures, docks, bridges, etc.
