Hebei Chiho Pipe Supply large stamping elbow elbow first large stamping press to its radius of curvature can be divided into long and short radius bend radius stamping stamping 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, namely R = 1.0D. (D elbow diameter, R is the radius of curvature) In terms of pressure levels to points, there are about seventeen kinds of stainless steel elbow, and the US standard pipe is the same, there are: Sch5s, Sch10s, Sch10, Sch20, Sch30, Sch40s , STD, Sch40, Sch60, Sch80s, XS; Sch80, Sch100, Sch120, Sch140, Sch160, XXS, one of the most common STD and XS are two kinds. According to the angle of bend points, 45 ° elbow with Elbow 90 ° and 180 ° elbow. The implementation of standards GB / T12459-2005, GB / T13401-2005, HG / T21635-1987, D-GD0219 like. Large stamping elbow statements: schxx wall thickness grade stainless steel elbow, 90e (s) for short radius 90 degree elbow; 90e (l) represents long radius 90 degree elbow; 45e (l) represents long radius 45 degree elbow ; 45e (s) for short radius 45 degree elbow; 180e (s) for short radius bend 180 degrees; 180e (l) represents a long-radius 180 degree elbow; r (c) represents concentric reducer fittings; r (e ) is an eccentric reducer fittings; t (s) represented Tee; t (r) represents reducing tee; cr (s) represented Equal Stone; cr (r) represents Reducing Stone; c represents pipe cap Large elbow refers to all materials and manufacturing methods, all interfaces in the form, all the pressure rating of the elbow (or other fittings), including stamping elbow. Hebei Chiho wear tube industry specializing in the production of stamping elbow. Wear a traditional stamping elbow elbow unmatched wear resistance, which is widely used in various pipe connections, thus also the emergence of a kind of a lot of wear elbow, wear elbow connection according to different ways and the structure is divided into the following types: wear stamping elbow wear-resistant steel with high-quality stainless steel elbow spot as the base material can be used in many cases are in the pipeline system as abrasive wear, corrosion, abrasion, erosion and wear. , impact wear, etc. In recent decades, low, development and application development quickly wear-resistant alloy steel, since these steels have good wear resistance and toughness, the production process is relatively simple, comprehensive economic and reasonable, in many working conditions applicable, and welcomed by users. It also makes the thick wear-resistant alloy elbow more widely, more and more low cost. wear stamping elbow favored more by business than the traditional elbow, and science and technology the continuous development and progress, constantly low wear elbow costs, making the industry position of the constant wear elbow firmly stamping elbow pipe wear characteristics of: 1, temperature and pressure, good flexibility, heat resistance, its performance than other plastic pipe. Installation is simple and good thermal conductivity is suitable for floor heating systems, recyclability .2, wear elbow pipe has its excellent impact strength, melt welding and mechanical connections, better than PB- PP-R thermal conductivity. Hot elbow pipe and other performance comparison 1, long-term pressure resistance, only in terms of design stress, pressure resistance wear elbow of the best. However, due to various factors, floor heating The actual wall thickness of the tube is usually 2mm; 2, environmental protection: hot elbow can be recycled, do not pollute the environment and PEX can not be recycled will produce secondary pollution; 3, flexibility: when construction does not require special tools, Therefore, the processing costs are relatively low, and PP-R hard to teach, processing costs are relatively high stainless steel elbows |.
