OHSAS 18001 PSL1 API 5L GrB Carbon Steel ERW Line Pipe

The urban gas pipeline network mainly uses ERW steel pipes, cast iron pipes and polyethylene (PE) pipes. From the perspective of safety and economy, that is, to ensure the quality of the project, the safety of gas supply and the adaptability of the gas pipe to the gas medium, and to reduce the project In terms of cost, ERW steel pipe is the first choice. Of course, according to local conditions, specific analysis and comprehensive judgment.

Huayang Steel Pipe represents domestic and international mills offering electric resistance welded (ERW) steel line pipe. Manufactured to API 5L specifications, our ERW line pipe is created by using high-frequency induction (HFI) currents to form a welded bond. Trident has partnered with industry-leading coating companies, offering the option for Fusion-Bonded Epoxy (FBE) coating, TGF-3 (Coal-Tar Epoxy), and other customer-specific coatings. A cost-effective option for pipe, our high yield ERW pipe is commonly used for well hook-ups, gathering lines, tie-in lines, trunk lines, and other midstream applications. Coated, job-ready material is available for same day shipment.

ERW steel pipe is the first choice for urban gas pipeline network. The main advantages and disadvantages are:
(1) High strength (large carrying capacity);
(2) The wall thickness is uniform and lighter than cast iron pipes of the same caliber; due to the high delivery pressure, it can be one grade smaller than the caliber of cast iron pipes of the same flow rate. Therefore, the total weight is reduced, the metal is saved, and the cost is reduced;
(3) Good plasticity, earthquake resistance and stress crack resistance;
(4) The inner wall of the ERW straight seam welded pipe is smooth, and the friction resistance is small, which avoids the precipitation of gas impurities and the pipeline transportation capacity is improved;
(5) It is suitable for wide temperature range, convenient construction, and tight welding interface. It can adapt to convey gas, liquefied petroleum gas mixed air and natural gas.
(6) However, in general, steel pipes have poor corrosion resistance, and anti-corrosion measures should be taken.

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.
