The pipe fittings are stamped into semi-annular elbows with high quality steel sheet by stamping die or cast directly into semi-annular elbows by casting die. Then two semi-annular elbows are welded in groups. Carbon steel elbows are resistant to weak corrosive media such as air, steam and water and chemical corrosive media such as acid, alkali and salt. The corrosion resistance of seamless carbon steel elbow is also very strong, not only will it not rust, but also will not breed bacteria, except for a few hydrogenating agents. Because of their differences in chemical composition, the former is not necessarily resistant to chemical erosion, while the latter is generally stainless. Soft-sealed butterfly valves are generally used on concave-convex flange sealing surfaces. Mengcun forged pipe fitting in the installation should pay attention to the sealing, to prevent leakage, affecting the normal operation of the pipeline. The improvement of carbon steel elbow not only increases the service life of carbon steel elbow, but also improves its working performance, so as to better connect pipelines, so that its compressive capacity will be enhanced a lot. Butt welding of annular workpieces such as automobile rim and bicycle, motorcycle rim, various chain rings, etc. The quality of high-pressure elbow is not only the quality of elbow, but also the packaging of high-pressure elbow. However, PEX can not be recycled and secondary pollution will occur; the development trend of seamless elbow pipe materials: seamless elbow raw materials not only have qualified creep rupture curve, but also have moderate pipe prices, construction is relatively convenient and fast compared with other varieties, the connection form belongs to the most reliable standard interfusion hot-melt connection at this stage, the hole diameter of pipe parts is larger than the inner diameter of the same specification pipe, in the system. Because there is no mechanical connection with local diameter reduction, the fluid resistance of the system is relatively small. During transportation, it should not be impacted or rained to prevent rust and oxidation. Carbon steel butt welded elbows are suitable for pipeline systems in petroleum, natural gas, chemical, hydropower, construction and boiler industries. If the carbon steel elbow is not treated by the above methods, in order to maximize the integrity of the carbon steel elbow, it is necessary to keep the carbon steel elbow dry and ventilated, keep the retainer clean and tidy, and store it in accordance with the correct storage method. Otherwise, the front-end outside diameter is usually large or small after the push head, which needs to be shaped by the shaping die.
