Hefei Shihua Pipe Fitting Co., Ltd. is a company specializing in the production of butt-welded pipe fittings. Its main products are various piping components including elbows, factory bends, return bends, reducers, tees,, stub ends, caps, manifolds, pigtails, riser & down corners, flanges, socket-welding fittings, etc., with materials of steel, titanium, nickel, zirconium, copper, aluminum and so on. Those products are widely used in petrochemical, electric power, metallurgy, shipbuilding, winemaking, textile, construction and other industries.
The company's leading products including seamless elbows, factory bends and return bends are all produced by medium-frequency induction hot pushing technology. Those products are featured of fine grain, compact structure, uniform wall thickness, reliable internal quality, accurate geometric dimension, natural and beautiful streamline, clean interior and exterior, and easy construction and installation. Those products produced by this technology are safe and reliable pipe fittings for petrochemical and electric power companies.
The company was founded in 1992. After being strictly checked and accepted by the Material Equipment Co., Ltd. of SINOPEC in 1994, it was among the ranks of “Member Factory in Resource Market” of SINOPEC. In 1996, it was absorbed as a “fixed-point factory for pipe fitting production” by the State Grid Anhui Electric Power Co., Ltd. and was famous for producing high pressure and non-standard difficult pipe fittings. In 2005, it was included in the “Member Factory in Resource Market” by PetroChina. In 2007, it was absorbed as a “Member Factory in Resource Market” by China National Offshore Oil Corporation (CNOOC).
The company is located in the national-level Hefei Economic and Technological Development Zone, covering an construction area of 50,000 m2, inducing a plant area of 20,000 m2, and having the existing staff of 180 people, of whom 36 were engineering and technical personnel. The company has more than RMB 60 Millions of fixed assets and more than RMB 60 millions of liquidity, as well as four medium-frequency induction hot pushing production lines, DN200, DN300, DN600 and DN1200; 3 sets of hot bending units for bends production, DN150, DN300 and DN800; 2 sets of hydraulic cold extruding units for tees production, DN200 and DN400; 3 sets of cold pushing units for stainless steel elbows production, DN100, DN300 and DN600; and 10 sets of 3000T, 1000T, 800T, 500T, 315T, 200T, 100T and 60T press.
