Production process of stainless steel butt welding elbow

Stainless steel butt welding elbow production process Stainless steel elbow is mainly used to effect the direction of the pipe through the elbow. According to the point of view, it can be basically divided into three normal conditions. Depending on the construction, it can also produce abnormal elbows from other viewpoints. The raw material of stainless steel is slightly better than the use of carbon steel elbow.

The chemical composition contained in it will keep the elbow from rusting for a long time and will not be corroded. Dividends can be divided according to the process: welded elbows, stamped elbows, hot-pressed elbows, push elbows, cast elbows, forged elbows, and elbows with many varieties. The raw materials and quality of stainless steel elbows are among the best in all kinds of steel. It has strong strength, large hardness, and strong toughness indicators. Its big strength is corrosion resistance, which is better in chemical paper making and other corrosion. It is more and more necessary to use stainless steel elbows in strong occasions. Although its cost is a bit high, it is not easy to replace and reduces the cost of use.

The raw materials for stainless steel elbows are: austenitic stainless steel, austenitic-ferritic stainless steel, ferritic stainless steel, martensitic stainless steel, deposition hardening stainless steel, etc. Austenitic stainless steels are not magnetic, and they are hardened primarily by cold working. Austenitic-ferritic stainless steel is a kind of magnetic stainless steel, which can be strengthened by cold working.

Ferritic stainless steel is a kind of magnetic stainless steel. It is a stainless steel that can be slightly strengthened by cold working. Martensitic stainless steel, its raw material is also a certain magnetic, and its mechanical properties can be adjusted by heat treatment. The precipitation hardening type stainless steel is strengthened by the treatment method of deposition hardening.

These stainless steels have different strengths, butt weld elbows are not easy to deform, have good sealing, and are widely used. They have corresponding rigidity and elasticity requirements and reasonable butt welding thinning transitions. The gap between the weld joint and the joint surface is large, and the joint surface is protected from welding temperature Deformed. The butt-welded elbow adopts a more complicated buckle-shaped structure.
