Large Diameter Butt Weld Fitting Mitered Elbow
The large diameter butt weld elbow is a steel hot pressed or forged elbow, which is connected in the form of a straight butt weld between the elbow and the steel pipe. To change the angle and direction of two pipes.
Large-diameter butt-weld elbow is a steel hot pressing or forging elbow, its connection is elbow and steel pipe butt-weld, large-diameter butt-weld elbow of the main design is usually GB / T12459, GB / T13401, ASME B16.9 , SH3408, SH3409, HG/T21635, HG/T21631, SY/T0510, GB/T10752, SY/T10752. T0510, GB/T10752-1995.
A large-diameter butt-weld elbow is used to connect two sections of pipe with different end radii, or for pipe redirection. This type of elbow is usually required to meet special engineering requirements or special drawings, in addition to the requirements of the pipe caliber, should consider the special conditions of the pipelines, such as high pressure pipelines, fluid viscosity, abrasiveness, corrosion. , hot water and other things. Most of the butt welding elbows are welded in place with pipes, which is due to the difference in welding standards for different types of pipes, which must be welded in place according to the pipe welding level.
Large diameter buttveld elbow according to the angle of the elbow, there are 45 ° buttvelld elbow, there are 90 ° buttvelld elbow and 180 ° butt welded elbow, etc. special elbows can often be adjusted according to the customer’s drawing to make.
Large diameter butt weld fittings generally include: carbon steel, alloy steel and stainless steel. Elbow according to its radius of curvature, can be divided into long-radius butt weld elbow and short-radius butt weld elbow. Long radius butt weld elbow radius of curvature is equal to 1.5 times the outside diameter of the tube, that is, R = 1.5 D. Short radius butt weld elbow radius of curvature is equal to the outside diameter of the tube, that is, R = 1 D. The formula D is the diameter of the butt weld elbow, R is the radius of curvature; if divided by pressure level, there are about seventeen kinds, and the United States pipe standards are the same, there are: Sch5s, Sch10s, Sch10 Sch20, Sch30, Sch40s, STD, Sch40, Sch60, Sch80s, XS; Sch80, Sch100, Sch120, Sch140, Sch160, XXS, of which the most commonly used are STD and XS
The best way to connect the large diameter butt weld elbow to the pipe is a direct weld, and a flanged connection.
1, because most of the pipe for welding, to improve the quality of welding, the end is turned into a bevel, leaving a feeling, with an edge, the need to be tighter, how thick, how much the thought is. and the mistake must be made. The surface quality and the body strength are the same as the pipe. For better welding convenience, the pipe and the pipe to be connected are the same type of metal.
2. All pipes must be treated with a layer of metal rust inside and outside is sprayed with injection blasting and then covered with anti-corrosion paint. This is to facilitate transportation to prevent rust and oxidation.
3, for the weight of the large-long butt-weld elbow must be packed separately, marked with the size of the specification, steel type, production batch number, manufacturer trademark.
Large diameter butt weld elbow area
Because the butt welding elbow has perfect performance, so it is widely used in construction engineering, water and drainage, chemical plant, oil and gas, light and heavy industry, liquid, sanitary, refrigeration, plumbing, electrical, electronic, shipbuilding, aerospace. technology and other construction
