Recently, the welded pipe production line of Shanghai Zhongyou Tianbao Steel Pipe Co., Ltd. was completed and put into production, adding new products to the domestic welded pipe market.
Founded in 2002, the company is the first domestic ERW steel pipe production and processing base jointly invested by Shenyang Zhongyou Tianbao (Group) Materials and Equipment Co., Ltd., China Petroleum and Natural Gas Pipeline Bureau and Shanghai Minhang District Pujiang Town Asset Management Co., Ltd. The PetroChina Tianbao welded pipe production line was completed and put into production, which indicates that China's ERW steel pipe manufacturing level and technology have entered the world's first industry.
The company invested 450 million yuan in the first phase of the project, introducing the world's most advanced ERWφ610 straight seam high-frequency electric resistance welded pipe manufacturing technology and equipment, and built the first domestic ERWφ610 production line, which can produce outer diameter of 219 mm to 630 mm, wall Straight-slot high-frequency electric resistance welded steel pipe with a thickness of 3.2 mm to 20 mm, with a maximum length of 18 m, and an annual output of 300,000 tons of various ERW steel pipes.
The products include X80 and below steel grades conforming to American Petroleum Institute (API) 5L standard and ducts conforming to GB/T9711.1-1997 and GB/T9711.2-1999 standards. H40 and J55 comply with American Petroleum Institute 5CT standard. K55 steel grade oil casing and square rectangular structural tube conforming to Japanese JIS3466 and GB/T6728-2002 standards, wherein the square tube size ranges from 200 mm × 200 mm to 500 mm × 500 mm, and the rectangular tube size is from 300 mm × 200 mm. To 600 mm × 400 mm, wall thickness 3.2 mm to 20 mm.
Among them, steel pipes with a diameter of 508 mm to 610 mm fill a gap in domestic ERW welded pipe products and can completely replace imported products. The company's products are widely used in oil and gas, construction, machinery, chemicals, metallurgy, mining, hydropower and other industries.
