Construction API 5L ASTM A500 Carbon Steel ERW Tube

Outer Diameter : 114.3mm - 812.8mm (4 " - 32 " ) Construction ERW Carbon Steel Pipe

Electric resistance welded (ERW) pipes are formed from steel coils using a continuous process that involves unfurling the coils, feeding the steel plates through tube mills, and then joining the edges longitudinally using electronicresistance welding. Misalignment of the plate edges can result in a deviation of the weld throughout the entire forming process.

Steel structure is the biggest advantage is to people to the functional requirement of the building, sensory demands and economic benefits together perfectly. Steel tube structure with its superior performance, the application of rapid development in recent years, application scope almost involve all fields structure, including buildings, Bridges and offshore platform structure and tower mast, etc.

Compared with the ordinary steel structure, the advantages of steel structure is as follows:

1, Compared with the ordinary open section steel, in the form of circular tube and square (torque) section has a smooth surface, no dead Angle and appearance characteristics of the area is small, it helps save anti-corrosion and fireproof coatings, easy to dust.

2, Small steel pipe section of the wind resistance coefficient, applied to the exposure to the fluid (wind, water)Who has obvious advantages.

3, The structure of the steel pipe internal space available. Filling concrete (concrete filled steel tube structure), for example, not only can improve the bearing capacity of components, but also can prolong the component fireproof limit (an average of 2 hours); Tube with water, can use the internal water circulation for fire prevention.

4, Pipe to transport liquid, has according to the characteristics of developed oil pipeline bridge, storm sewer, etc.

5, The tube can also put the prestressed cable, applying prestress in the body.

Size & Thickness:

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.
