Oil Pipeline API 5L PSL1 X42 Straight Seam Welded Pipe

The advantages and disadvantages of welded steel pipe
The average wall thickness of the tube light table table high (steel exterior appearance of steel grade resolution, brightness) can be arbitrary length. Thus, it showed its economy and aesthetics in accuracy, the use of low-pressure fluid.
Welded steel pipe production process is simple, high production efficiency, low cost, to carry out faster. Spiral Welded Longitudinal higher than normal, can narrow the billet production of large diameter pipe, you can use the differences diameter pipe billet production of the same width. What, then with the same length of straight pipe joints compared weld length add 30 to 100%, and lower production rate. Thus, most of the smaller diameter pipe straight seam welded, large diameter spiral welded pipe for the most.

Classification of welded steel pipe
1, High frequency welded steel pipe features: tubular good, uniform thickness, internal and external burrs produced by the welding tool calibrating the appropriate online through strict control of non-destructive testing of weld quality, high degree of automation, low production costs. But relatively thin wall thickness, diameter is relatively small, usually no more than a wall thickness of 12mm, diameter generally does not exceed 610mm, particularly suitable for the production of steel tube truss structure.
2, LSAW pipe features: welding under static conditions, high weld quality, short welds, the probability is very small defects. By expanding full-length steel tubular good, precise size, wide range of pipe wall thickness and diameter range, the diameter range up 406-1829mm, wall thickness range up 6.0-60mm, high degree of automation, Compared to seamless steel, it is lower production costs, for buildings, bridges, dams, offshore platforms and other steel bearing with columns, large span structures as well as wind and seismic requirements for electrical tower mast structure.

3, Spiral submerged arc welded pipe features: spiral weld line distribution, long welds, especially

Hebei Huayang Steel Pipe Company Ltd. is the largest ERW and LSAW steel pipe manufacturer in Northern China. Established in 2005, we have a modern factory covering an area of 666,000 square meters, with over 700 employees and a fixed asset of 200 million USD, annual output capacity is up to 1,000,000 Tons. We can quickly fulfill all of our domestic and international customers’ orders, try our best to meet customers’ requirements.

We are located in Cangzhou city, Hebei province, a large steel production base in Northern China. Huayang is near to the raw material steel mill, such as Hebei Zhongtie Equipment Company, Shandong Iron and Steel Co., Ltd, Shougang Group, Jinxi Group, which reduce the material cost. At the same time, Huayang is 210 kilometers from Beijing, 150 kilometers from Tianjin City, 160 kilometers from Xingang port, with convenient transportation, which is convenient for customer’s visit and reduce the transportation cost. With lower material cost control, we can offer more competitive price and significant profit for our customers.

Huayang use advanced imported production equipment such as German once-through rolling machines, British CT METORI digital controllers, one φ114.3mm-φ168.3mm ERW steel production line, three φ219mm-φ426mm ERW steel pipe production line, one φ426mm-φ660mm ERW steel pipe production line, one JCOE production lines for LSAW pipe, size range from 16” to 56” (406.4mm-1422.4mm), wall thickness: 9.53mm-50mm. In 2018, we build a new advanced RBE production line for LSAW pipe, size range from 16” to 56” (406.4mm-1422.4mm), wall thickness: 9.53mm-30mm.

Twenty φ245mm-φ820mm thermal expansion pipe production lines, we have our own high-tech physics and chemistry labs where we can conduct our own tests such as physical properties and chemical composition test, and as well, UT, hydraulic test, X-ray and other test equipment is available, which can meet all related standards and inspection requirements.

In order to provide One-Stop service for customers with superior products from qualified supplier, Huayang set up branch company, Cangzhou Wingo International Trading Co., Ltd in 2013, to help customers purchase different products, such as seamless steel pipes, SSAW steel pipes, Galvanized pipes, Anti-corrosion pipes, pipe fittings and flanges etc.

Huayang steel pipes are used as the construction material and the pipelines for oil, gas, water, steam, and other middle & low hydraulic pressure fluids. Huayang’s products are sold nationwide and mainly exported to Southeast Asia, Middle East, South America, Africa, North America and Europe. Our company has consistently aimed to provide our customers with high quality, affordable industrial pipes. “Huayang” brand steel pipe has gained praises and high reputation from all of the world.
