  Spectacle Blind Flange factory Flanges are also called flange flanges or flanges. Spectacle Blind Flange is a part that connects between shaft and shaft and is used for connection between pipe ends; it is also useful for flanges on the inlet and outlet of equipment for connection between two equipment, such as reducer flange. Let’s follow the editor of Spectacle Blind Flange to take a look at its welding process! Spectacle Blind Flange factory Preparation before welding 1. Check and debug the equipment to ensure that the equipment is operating normally. 2. Spectacle Blind Flange factory To prepare φ4.0J402 welding rod, it is recommended to dry it at 300℃-350℃ for one hour. Spectacle Blind Flange factory the welding process 1. Spectacle Blind Flange company Assembly Assemble the cone and the large flange according to the drawing requirements, and then divide the large flange into 8 equal parts. 2. Spectacle Blind Flange company Welding Because the flange is thicker and the groove is larger, segmented symmetrical and multilayer welding is adopted. 3. Spectacle Blind Flange company 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.

  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.
