Precautions for Stamping and Bending Pipe Processing
Release time:
Sep 22,2021
Bend pipes produced by stamping have been widely adopted and promoted across various fields and industries. These stamped bend pipes are formed using stamping dies made from the same material as the pipe fittings, after which two semi-circular bent pipes are welded together in batches. The welding of stamped bend pipes must be carried out according to specific manufacturing processes. Since welding standards differ among various types of pipelines, these pipes are typically delivered as pre-assembled semi-finished products. During on-site construction, they are welded according to the pipeline’s specific welding grade; hence, they are also referred to as “two-half stamped bend pipes.”
Stamping Bent pipe The characteristics
Stamping Bent pipe It has been widely applied and promoted across various fields and industries. Stamping Bent pipe Formed using a stamping die made from the same material as the pipe fittings, then two half-rings are welded together in bulk. Bent pipe Stamping Bent pipe Welding must be carried out according to specific manufacturing processes. Since welding standards vary among different types of pipelines, the components are typically pre-assembled into semi-finished products grouped together. During on-site construction, these components are welded according to the pipeline’s specified welding grade; thus, this method is also referred to as “two-half stamping.” Bent pipe 。
Stamping Bent pipe The characteristics
1. Stamping Bent pipe It is relatively hard and prone to cracking after welding. To ensure post-weld quality, different welding electrodes should be selected during the welding process. If the same chrome-plated stamped parts are used... Bent pipe When performing covered electrode welding, the workpiece must be preheated to... 300 Above, after welding, cool slowly to 700 Left and right.
2. Stamping Bent pipe With excellent corrosion resistance and oxidation resistance, its superior performance has facilitated its widespread application and promotion across various fields, and it is now extensively used in industries such as chemical engineering, fertilizer production, petroleum, and medical equipment.
3. Stamping Bent pipe It possesses certain corrosion resistance, heat resistance, and wear resistance, and is commonly used as a material for equipment in power plants, chemical industries, petroleum industries, and more. Stainless steel stamping. Bent pipe Its weldability is relatively poor; therefore, attention should be paid to the welding process and heat treatment conditions.
4. Stamping Bent pipe Coated with titanium-calcium and low-hydrogen types. The calcium type can be used for both AC and... DC However, fusion welding is relatively shallow and tends to cause reddening, so stainless steel stamping... Bent pipe Should be used whenever possible. DC Power supply.
Stamping Bent pipe Precautions during processing
1. Stamping Bent pipe After welding, it exhibits high hardenability and is prone to cracking. During welding, different electrodes should be used to ensure proper weld quality and stamping performance. Bent pipe the quality. If the same type of chrome-plated stamping is used Bent pipe For weld overlay with welding electrodes, preheating is mandatory to... 300 Above, after welding, in... 700 Cool slowly from left to right. If the welded component cannot be heat-treated after welding, Bent pipe Should be stamped with chrome-nickel. Different types of coated electrodes exhibit varying performance and characteristics during use; therefore, they should be selected according to the corresponding requirements to ensure proper stamping. Bent pipe the quality of.
2. To improve stamping Bent pipe For improved corrosion resistance and weldability, stabilizing elements such as titanium, niobium, and molybdenum should be appropriately added during the manufacturing process. Its weldability is superior to that of chromium-stamped materials. Bent pipe Use stamped chromium stainless steel of the same model. Bent pipe At that time, preheating should be performed after welding. 200 Above, tempering. 800 Right. If the welded component cannot undergo heat treatment, Bent pipe Should be stamped from chromium-nickel stainless steel.
3. Stamping Bent pipe Its excellent corrosion resistance and oxidation resistance have promoted its use and widespread adoption in various fields, including petrochemicals, fertilizer production, healthcare, and mechanical manufacturing.
4. Stamping Bent pipe Has a certain degree of corrosion resistance. ( Oxidizing acids, organic acids, cavitation ) Heat resistance and wear resistance—typically used in equipment and materials for power plants, chemical industries, petroleum, and other sectors. Stainless steel stamping. Bent pipe Its weldability is relatively poor; therefore, attention should be paid to the selection of welding processes, heat treatment conditions, and electrodes.
5. Stamping Bent pipe It comes with titanium-calcium and low-hydrogen coatings. The titanium type can be used for AC. /DC Welding—however, when using AC welding, the penetration is shallower and it’s easier for the weld to turn red. Therefore, stainless steel stamping... Bent pipe Should be used whenever possible. DC Power. 6. Stamping Bent pipe It should be kept dry during use. Perovskite-type materials should... 150 Dry 1 Hours, the low-hydrogen type should be 200-250 Dry 1 Hour.
7. Welding stamping Bent pipe At that time, heating will cause carbides to be released; repeated heating will lead to the precipitation of carbides. The precipitated carbides can affect stamping. Bent pipe its performance, reducing its corrosion resistance and mechanical properties.
The above is the stamping process introduced earlier. Bent pipe Some precautions and features to keep in mind during processing—hopefully, these will be helpful to everyone.
