It has various materials and wide application of the alloy elbow. Common bronze alloy elbows are common in common tap water pipelines, but with the improvement of living standard, a lot of tap water pipelines are changed into stainless steel elbows. The alloy elbow has stronger heat resistance and corrosion resistance due to the composition and structural characteristics of R alpha carbide and a matrix with solid solution content of Cr, the alloy elbow shows good corrosion resistance and wear resistance in a high-temperature or corrosive environment by adding Mo, and the alloy elbow is more compact in internal structure by adding a certain amount of rare earth, and a layer of protective film is formed on the surface of the alloy elbow to prevent carbon from seeping. The alloy elbow has increased wear resistance and corrosion resistance, contains a certain amount of boron to change the alloy hardness into hardness which can not be achieved by recarburization, and simultaneously contains a certain amount of Mn to increase the fatigue resistance of the alloy to shock resistance, so that the wear resistance of the alloy is superior to that of high-chromium alloy and rare earth alloy.

C. assembling a workpiece: the rubber gasket is arranged in the locking block, the anode lining is properly bent and deformed until the anode lining can penetrate into the alloy elbow, then the locking block on the anode lining penetrates through the limiting hole of the alloy elbow by using a tool, the locking handle is operated to penetrate the locking pestle through the rectangular through hole of the locking block and then is rotated to complete the self-locking of the locking assembly, and finally the deformed anode lining is adjusted to the original shape by using the tool.
