Description
Weld ring gaskets are commonly used in areas where dangerous media is conveyed and/or continuous operation of the plant has to be ensured. A permanent and gas tight connection is established by welding the membrane or weld ring halves. This ensures the required high operational safety and continuity, while it is still possible to release the flange connection by undoing the welding seam.
Weld ring gaskets consist of two identical ring halves which have been machined with greatest precision, were welded to the flange surface and then welded together after positioning the flange halves.
IDT-weld-ring-gaskets are manufactured following DIN 2695: 2002 for DIN- and ANSI/ASME-flanges [SW01, SW10] and according to company standards [SW19, SW20, SW29]. The thickness of the welded rings is 2 x 15 = 30.0 mm for the designs SW10 and SW20, which allows for the welding of the ring halves without a special flange. The SW19 profile provides an additional auxiliary gasket. Prior to installation, the flange surfaces need to be checked for sufficient space.
Welding ring gaskets are commonly made from the same or similar material as the pipe or flange material.
