The production steps of stainless steel seamless elbow can be divided into material selection, cutting, hot press bending, welding, straightening, surface treatment, etc.
Material selection:
In addition to stainless steel, seamless elbows also have alloy steel and carbon steel as raw materials, which can be selected according to the actual use environment and requirements.
Cutting:
Cut the raw materials into appropriate lengths according to design requirements, generally using cutting equipment to ensure smooth and vertical cuts.
Hot press bending:
After the cutting is completed, the raw material is bent through hot press bending equipment, heated to a certain temperature, and the pressure is used to bend the material into the desired shape.
welding:
After hot pressing and bending, the raw materials are welded. Welding can connect the various parts of the elbow together and ensure the quality of the weld.
Straightening:
After the welding is completed, place the elbow on the straightening equipment, and adjust the equipment to eliminate the deformation and unevenness of the elbow.
Surface treatment:
After straightening, surface treatment is performed on the elbow. Surface treatment generally includes rust removal, oil removal, pickling, sandblasting, painting and other processes, which can improve its corrosion resistance and aesthetics.
