Hebei Chiho-walled seamless tube industry is the raw material stamping elbow round tube, tube embryos to go after cutting a length of about one meter cutter blank, and by conveyor belt to the furnace heating. Perforation, round tube has been three-roll rolling, rolling or extrusion. After pressing to take off pipe sizing. Sizing machine rotating at high speed through the cone drill steel embryo into perforated to form the tube. Thick-walled seamless because of different manufacturing processes stamping elbow stainless steel elbow, pressing elbow is divided into hot-rolled seamless cold drawn seamless pipe and pipe fittings elbow punching two kinds. Thick-walled seamless stamping elbow Specifications: DN10-DN2000 Material: carbon steel, cast steel, alloy steel, stainless steel and other production processes: pushing, pressing, forging, casting and other production standards: GB, electricity standard, water standard, American Standard, the German standard, the Japanese standard, the British standard thick-walled seamless elbow with good wear resistance, compression and strong industrial stainless steel elbow, corrosion resistance, suitable for high temperature and high pressure piping and mechanical equipment. Hebei Chiho Pipe Co., Ltd. specializing in the production of carbon steel stamping elbow. Steel stamping elbow are made of carbon steel, stainless steel, alloy steel and other materials. Carbon steel stamping elbow is cheap, large. The alloy is used in a special elbow position. Stainless steel stamping elbow elbow distinguish different materials mainly stainless steel elbow plant, which contains the chemical composition of the surface for a long time will remain the elbow will not rust, corrode easily. Stainless steel to stainless steel elbow, the main characteristics of the corrosion resistance, and a chromium content of at least 10.5%, the maximum carbon content does not exceed 1.2% of the steel. 90 ° stainless steel elbow, Hebei Chiho (certified), stainless steel elbow by Chiho Hebei Industry Co., Ltd.
