DIN 2458 1422mm Longitudinal Submerged Arc Welded Pipes

Outer Diameter : 406.4mm -1422mm (16 ”-56 ”) Water LSAW Steel Pipe

LSAW ( Large-Surface Submerged-Arc Welded Pipe ) is produced by using a single medium-thickness plate as a raw material, and pressing (rolling) the steel plate into a tube blank in a mold or a molding machine, adopting a double-sided submerged arc welding method and expanding the diameter. Its product specification range is wide, the toughness, plasticity, uniformity and compactness of the weld seam are good. It has the advantages of large diameter, thick wall thickness, high pressure resistance, low temperature resistance and strong corrosion resistance. When building high-strength, high-toughness, high-quality long-distance oil and gas pipelines, most of the required steel pipes are large-caliber thick-walled LSAW pipes. According to API standards, LSAW pipe is the only designated type of pipe to be used in large-scale oil and gas transmission pipelines when passing through Class 1 or Class 2 areas such as the alpine zone, submarine, and densely populated urban areas. According to different molding methods, they can be divided into:

UOE welded pipe: single steel plate after the edge of pre-bending, after U molding, O molding, internal welding, welding, mechanical cold expansion and other processes;

JCOE welded pipe: press “J-C-O-E” pre-welding, forming, welding, cold expansion and other processes;

HME welded pipe: It is formed by the “C-C-O” method of mandrel rolling method, and the process of cold expansion after welding.

By carrying out standard Non-Destructive Detections on our LSAW pipes, we ensure that our pipes serve our customers well. Our LSAW steel pipes are ideal pipes for large-scale pipeline water transportation.

Our Advantage:

Huayang specialized in manufacturing welded carbon steel pipes for 14 years. The annual output is around 1050,000 tons. Our products have been exported to 40 countries and regions till now, such as Canada, Hong Kong, Vietnam, Bangladesh, The U.A.E, America, Spain, Italy, Netherlands, Kuwait, Saudi Arabia etc. So any inquiry or special demands will get fast and most professional reply.

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.
