S355J2H Submerged Arc Welded Pipe

EN 10219 S355J2H Submerged Arc Welded Pipe For marine offshore field

Longitudinal submerged arc welded pipe (LSAW pipe for short). Longitudinal Submerged Arc Welding (LSAW) is a process of pressing (rolling) steel plate into the billet of die or forming machine, using single plate as raw material. Double-sided submerged arc welding is used to enlarge the diameter. The finished product has complete specifications, good weld toughness, good plasticity, uniformity, compactness, large diameter, thick wall, high pressure, low temperature and corrosion resistance.


the LSAW Steel pipe EN 10219 S355J2H Hot Finished Structural Hollow Sections is often used in civil engineering and bridge engineering as well2as for water engineering. Additionally, the vehicle S355JRH EN 10219 Steel Hot Finished Square Pipe is also used in not only construction but also mechanical engineering as well. Another important feature of this Steel EN 10219 S335J2H Hollow Section is that the alloy can be welded by easily. For instance, standard welding procedures such as TIG, ARC and SAW welding could be used to weld the EN 10219 S335J2H Steel Hollow Section. Apart from these standard procedures, our clients can use the more conventionally used MAG i.e. – welding by both core wire as well as massive wire to weld this grade of Steel S355J2H EN 10219 Square Tube. Although this carbon based En 10219 Din 2395 S335J2H RHS would require the addition of a filler metal in order to conduct a welding process. A point to note is that the EN 10219 S355J2H Steel Pipe is magnetizable.

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.
