Peng Hebei Cangzhou Pipe Co., Ltd. (www.czpygy.com) is located in Cangzhou, Hebei Yanshan, Contact: Wang Lin 180 degrees 180 degrees elbow bend technology standards and quality control: Feed - Physical - cutting - Forging Forming - Heat Treatment - Testing - gold processing - product testing - Identification - product testing - Identification - Packaging typing - shipped. 180 degree elbow materials are cast iron, stainless steel, alloy steel, malleable cast iron, carbon steel, non-ferrous metals and plastics. And tubes welded directly connected with the way (the most common way) flanged, threaded coupling and socket type connection and so on. Production Standard: GB12459-90, GB12401-90, ASME / ANSI B16.9, DIN, JIS, ISO and other standards. Production range: DN6-DN1200 (1/8 "-48") of large diameter carbon steel seamless elbow, complete specifications. 180 degree elbow Uses: Widely used in: beer, beverage, food, paper, pharmaceutical, construction, electricity, petroleum, chemical, sewage treatment and other industries, to facilitate the construction of various industries to provide piping. Stamping, welding and stamping elbow elbow elbow large diameter seamless steel manufacturers, which use the same material of the plate and pipe stamping die stamping elbow into halves can be customized large-diameter circular seamless carbon steel elbow, and then the two elbow and a half ring group formed to carry out the welding. Because different types of pipeline welding standards, usually on a fixed spot by group of semi-finished factory, construction site welding of large diameter steel shelf seamless elbow pipe welds according to grade, therefore, also known as the two halves welded elbow . Elbow appearance inside and outside using cold extrusion die manufacturing process, uniform thickness, small size deviation, so especially for thin-walled stainless steel elbow stainless steel elbow forming multi-use of this process. This inner and outer mold process used precision high; tube wall thickness deviation requirements are more demanding.
