socket weld elbow
Socket welded elbows is a type of socket welded fitting that is unthreaded, but has large sockets at both ends of a pipe. We offer wide range of socket weld 90 degree socket welded elbows. These fittings have center to face dimension and are typically used in tight areas where clearances are an issue. They are mostly used for changing the direction in piping and are also sometimes called a quarter bend.
1. Material: 304, 304L, 321, 316, 316L, etc.
2. Standard: ASME, MSS, HG, DIN, JIS, GB
3. Type: 90° and 45° Socket Welded Elbow
We offer Sanitary Fittings, Stainless Steel Sanitary Fittings, and Stainless Steel Tube Fittings that are manufactured using optimum quality stainless steel. Our wide array of sanitary stainless steel tee is known among the customer's due to its tensile strength. These Steel Tube Fittings in various grades and finishes as per the needs.

Application of Stainless Steel Socket Weld Elbow
SW Fittings are family of high pressure fittings are used in various industrial processes.
1. They are used for lines conveying flammable, toxic or expensive material where no leakage can be permitted, and for steam 300 to 600 PSI.
2. They are used only in conjunction with ASME Pipe and are available in the same size range.
3. They are used in areas where pipe-work is permanent and are designed to provide good flow characteristics.
4. They are produced to several ASTM standards and are manufactured in accordance with ASME B16.11. The B16.11 standard covers pressure-temperature ratings, dimensions, tolerances, marking, and material requirements for forged carbon and alloy steel. Acceptable material forms are forgings, bars, seamless pipe, and seamless tubes which conform to the fittings chemical compositions, melting practices, and mechanical property requirements of ASTM A105, A182, or A350.
5. They are available in three pressure ratings: 3000lbs, 6000lbs and 9000lbs.
Features of Stainless Steel Socket Weld Elbow
1. The pipe need not be beveled for weld preparation.
2. Temporary tack welding is no needed for alignment, because in principle the fitting ensures proper alignment.
3. The weld metal can not penetrate into the bore of the pipe.
4. They can be used in place of threaded fittings, so the risk of leakage is much smaller.
5. Radiography is not practical on the fillet weld; therefore correct fitting and welding is crucial. The fillet weld may be inspected by surface examination, magnetic particle (MP), or liquid penetrant (PT) examination methods.
6. Construction costs are lower than with butt-welded joints due to the lack of exacting fit-up requirements and elimination of special machining for butt weld end preparation.
