Stainless Steel Socket Weld Elbow

Stainless Steel 45 DEG Socket Weld Elbow
Stainless Steel 90 DEG Socket Weld Elbow

Stainless steel socket weld elbow is an important pipe fitting. It formed by molding and forging blanks from round steel or steel ingots, and then processed by lathe machine.

According to the angle, it can be divided into 45 degree and 90 degree socket elbow. It can meet the needs of different pipelines.

Stainless steel socket weld elbows are made of stainless steel material and have excellent corrosion resistance and high temperature resistance. They are widely used in various industries, especially in chemical, metallurgical, power, shipbuilding and other fields.
