quality SO Flange is also called flange flange or flange. SO Flange is a part that connects between shaft and shaft, used for connection between pipe ends; SO Flange is also used at the inlet and outlet of equipment, used for connection between two equipment, such as reducer flange. Let's take a look at its welding process. 1. good price and quality SO Flange Preparation before welding 2. SO Flange manufacturers Check and debug the equipment to ensure that the equipment is operating normally. 3. To prepare φ4.0J402 welding rod, it is recommended to dry it at 300℃-350℃ for one hour. Second, good price and quality SO Flange the welding process 1. SO Flange manufacturers Assembly Assemble the cone and the large SO Flange according to the drawing requirements, and then divide the large SO Flange into 8 equal parts. 2. Welding Because the SO Flange is thicker and the groove is larger, it adopts segmented symmetrical, multi-layer welding. 3. SO Flange manufacturers Weld quality The weld strength is required to reach at least the strength of the base metal. The surface of the welding seam is flat and smooth, and there are no defects such as burn through, pores, weld leakage, slag inclusion, undercut, and insufficient weld. The remaining height is less than 2mm.
