There are many types of elbow welding.There are also many types of butt welds, such as the reduction of the diameter of the end of the butt weld elbow or part of the pipe diameter, the wall thickness of the butt weld elbow means that the wall thickness occurs along the length of the pipe, etc.
In order to achieve the expected derusting effect of the welding elbow, the abrasive should be selected according to the surface hardness of the direct welded pipe and the surface roughness coating type required by the original corrosion.For single epoxy double layer or three layer polyethylene coating, it is easier to achieve the ideal derusting effect by using steel sand and ball mixed abrasive.According to the Angle of the core head, there are two kinds.Core rods are used for flame heating.The constitutive relation of the material is established, and the stress-strain field in the forming process of thermostatic bending pipe is described, and the experimental results are verified.Features are described in English letters and Numbers.The number of metal alloy materials and other words specify the type of steelmaking process, the composition multiple, carbon content and tensile strength of the main alloy.The precautions are as follows: long-term storage of stainless steel flange, should arrange inspection, often exposed surface must be kept clean, remove dirt, neatly stored in dry indoor place, no accumulation or open storage.
