Duplex Steel Socket Weld Flanges, Monel SWRF Flanges Dealers & Trader
The socket weld flange is attached by only one fillet weld and is used for small-bore lines only. SW Flange is very similar to slip on flange but their fatigue strength is 50% greater. Space is created between flange and pipe to ensure proper bore dimension.
The purpose for bottoming clearance of socket weld flange is to reduce the residual tension that occurs during solidification of weld metal. They are manufactured in accordance with ASME B16.11 SWRF Flanges which helps in covering pressure-temperature ratings, dimensions, tolerances, marking and material requirements.
They are available in three ratings: Class 3000, 6000 and 9000. Several advantages of socket weld flange are that it is not required to be beveled for weld preparation, construction costs are lower and it cannot penetrate into the bore of the flange. The disadvantages of using these flanges are that they are unacceptable for Ultra High Hydrostatic Pressure, don’t allow penetration and leave overlaps and crevices which are difficult to clean leading to virtual leaks.
