Stainless Steel 90 Degree Elbow

What is a Stainless Steel 90 Degree Elbow?

90 degree elbows, also called "90 bends or 90 elbows", are manufactured as SR (Short Radius) elbows and LR (Long Radius) elbows. The raw materials used for manufacturing 90 degree stainless steel elbow are seamless or welded stainless steel pipes. Elbows are mainly produced by cold forming, followed by heat treatment, pickling, finishing and other activities.

Advantages of use of Buttweld Fittings

A piping system using buttweld fittings has many inherent advantages over other forms.
1. Welding a fitting to the pipe means it is permanently leakproof
2. The continuous metal structure formed between pipe and fitting adds strength to the system
3. Smooth inner surface and gradual directional changes reduce pressure losses and turbulence and minimize the action of corrosion and erosion
4. A welded system utilizes a minimum of space
