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.
ERW steel pipe is straight weld pipe, electric resistance welding, the abbreviation for ERW for transporting oil and natural gas vapor liquid objects, can meet the requirements of high and low pressure, the transport in the world with pipe sector accounted for a pivotal position.
ERW tube is a "high frequency resistance welded steel pipe", and the common welded pipe welding process is not the same, the welding seam is made from the steel body of the base metal, the mechanical strength is better than the general welded pipe.
chA53B Chemical component
ERW pipe is due to the use of hot-rolled coil as raw material, uniform wall thickness can be controlled at about +- 0.2mm, the two ends of the steel pipe according to the APL standard and GB / t9711.1 standard, end trimming hit groove, fixed length delivery and other advantages. In recent years, the natural gas pipeline network engineering and gas companies have been widely used ERW pipe as the main pipe network of the city.
The pipe is for Fluid transport and Construction mostly used in industries as Coal gas, Steam, Water,
Petroleum, Natural gas.
Huayang specialized in manufacturing welded carbon steel pipes for 14 years. The annual output is around 800,000 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.
