Butt-welding elbow is a kind of elbow for connecting pipes, which can be used to connect two pipes turning in different directions, so that the whole pipeline can be arranged more flexibly.
A butt-welding elbow material
Butt-welding elbow material is generally selected with the same material as the pipeline, such as carbon steel, stainless steel, alloy steel and so on. At the same time, you also need to choose the appropriate material according to the use of occasions, fluid properties and other factors. For example, if the flow of corrosive liquids in the pipeline, then you need to use materials that can resist corrosion.
Second, the manufacturing process of butt-welding elbow
Butt-welding elbow manufacturing process usually includes the following steps:
1. Cutting materials
First of all, you need to cut the selected material, after cutting to check whether the cut is flat, burr-free and other issues.
2. Heating the material
Butt-welding elbow needs to heat the pipe and elbow in order to form a good weld at the interface. The temperature and time of heating vary according to the material.
3. Forming
After the heating is completed, the pipe and elbow are placed into a forming mold and shaped with pressure. After molding, inspection is required to ensure that they meet the specified dimensional requirements.
4. Welding
The formed pipe and elbow are butt-welded. Butt welding involves joining two pipes together by butt welding elbows. This involves welding with a flux-coated welding rod and controlling the welding current and voltage.
5. Inspection
After the butt-welding elbow is manufactured, it needs to be strictly inspected. Inspection includes welding quality, dimensional accuracy and other aspects. Need to ensure that the butt-welding elbow can withstand the test of high pressure and high temperature and other adverse conditions.
