Chiho Hebei Industry stamping elbow high pressure pipe connections, including a curved pipe, characterized in an arcuate elbow integrally connected with a shunt-through. The utility model has reasonable structure, make piping by force can be simplified piping system, easy to operate, energy saving investment, reduce the pipe resistance, optimized piping arrangement, and can help reduce the cost of running a balanced flow distribution, reduce the piping vibration, ensure the safe operation of equipment and pipelines advantages Bend material head cast iron, stainless steel, alloy steel, malleable iron, steel, nonferrous metals and plastics, and the pipe coupling methods are: direct welding (the most common way) flanged, threaded coupling and socket-type coupling et al. in accordance with the production process can be divided into: welding elbow, pressing elbow, casting elbow 45 degrees elbow high pressure stamping technical requirements: 1. As the most used for welding pipe fittings, in order to improve the quality of welding, the ends of both cars into the slope mouth, leaving a certain angle with a certain edge, this one is also more stringent requirements, while more thick, and deviation angle range has a predetermined number of surface quality and mechanical properties of basic and tubes are the same. In order to facilitate welding, fittings and steel pipe is connected is the same .2 that all the pipe pieces to go through a surface treatment, the inner and outer surfaces of oxide scale spraying out by shot peening, and then coated with anti-corrosion paint. This is to export needs, Furthermore, in the country but also to facilitate transport to prevent corrosion oxidation, have to do this work .3 is to packaging requirements for small fittings, such as export Shangluo stamping elbow dn200, we need to do a wooden box, about one cubic meter the provisions in this case can not exceed the number of elbows about a ton, the standard allows suits that large sets of small, but the total weight is generally not more than 1 ton. For large y should a single package, like 24 "must a single package. The other is the package label Shangluo stamping elbow dn200, marked to indicate size, steel number, batch number, manufacturers such as trademarks. Hebei Chiho tube industry production and sales of stamping steel elbow, carbon steel stamping elbow classification, according to its radius of curvature can be divided into long radius elbows and short radius elbow, long radius elbow refers to its radius of curvature is equal to 1.5 times the pipe diameter, namely R = 1.5D. Short Radius elbow refers to its radius of curvature is equal to the pipe diameter, that is R = D. formula for the bend diameter D, R is the radius of curvature. If the press pressure levels to sub Shangluo stamping elbow dn200, there are about seventeen, and US standard pipe is the same advantages as steel stamping elbow production process mainly in the following aspects: First, carbon steel stamping elbow for petroleum, natural gas, chemicals, utilities, construction and boiler piping industry system. Second, without tube for raw materials, equipment and pipe can save tooling costs and obtain arbitrarily large diameter and wall thickness of the relatively thin carbon steel elbow. Third, the blank is flat or curved stamping developable surface Shangluo head dn200, thus cutting simple, easy to ensure accuracy, easy assembly and welding. Fourth, the above two reasons, you can shorten the manufacturing cycle, the production cost is greatly reduced. because does not require any special equipment, especially for on-site machining of large steel elbow 180 Shangluo stamping stamping elbow elbow _ _ Hebei Chiho Chiho by Hebei Industry Co., Ltd.
