Shandong Huafeng Steel Pipe Co., Ltd. is a company specializing in seamless steel precision seamless steel pipe, steel pipe, precision steel, special steel pipe, welded pipe production and sales of the modern enterprise. Precision steel oil quenching can lead to deterioration of the surface. Since the surface-active Shanghai precision seamless, remarkably thin carburizing can occur at high temperature short film role, in addition, carbon black and oil adheres to the surface of the heat treatment process to simplify very unfavorable. Development of vacuum hardening technique include research performance, single-station gas quenching furnace. Our company has a large and small precision seamless cold drawn or cold rolled precision light tube machine six production lines Zhejiang precision seamless steel pipe prices, roller hearth heat treatment furnace two, three ordinary cold drawn seamless unit, production outside diameter 10-108mm wall thickness 1-16mm of precision steel, precision seamless material is on the 10th, the 20th, No. 45, 16Mn, GCr15,40Cr other precision seamless steel pipe manufacturing plant, the main other pipe: bearing steel, 16MN steel, 42crmo steel, 20g high-pressure boiler tube, 45 steel pipe, galvanized steel pipe precision bright. Seamless inner hole can be divided into round, spline type, plum-type and other widely used in automobiles, motorcycles, hydraulic, petrochemical, shipbuilding, aerospace, bearings, pneumatic components, fuel tanks, boiler equipment, medical equipment, fitness equipment and other industries fields. The company not only itself but also in the production of seamless steel Chengdu Iron and Steel Group, Hubei Daye Steel Group, Baotou Seamless Steel Tube Plant, Tianjin Seamless Steel Group, Guangzhou Lianzhong, Changcheng Special Steel, Walsin, long-established steel, Wenzhou Baofeng Shanxi Taiyuan, Shanghai Baosteel, establish long-term business, annual sales specifications ∮4mm-1220mm × 1mm-120mm of seamless pipe, stainless steel pipe, stainless steel plate, stainless steel bar, stainless steel square and rectangular tubes, plates, transmission fluid high, medium and low pressure boiler pipe, oil cracking pipe, fertilizer, ship management and domestic and imported alloy tubes.
