Duplex Steel S31803 Weld Neck Flanges is not easy to deformation, good sealing, widely used, suitable for pressure or temperature fluctuations of the pipeline or high temperature, high pressure and low temperature pipeline, the advantage is that the price is relatively cheap, nominal pressure does not exceed 2.5MPa; Also used for conveying expensive, flammable, explosive medium pipeline, nominal pressure in PN16MPa.

316 Stainless Steel Slip on Flange is not only saves space, reduces weight, more important is to ensure that the joint parts will not leak, with good sealing performance. The compact flange size is reduced by reducing the diameter of the seal, which will reduce the cross section of the sealing surface. Secondly, the flange gasket has been replaced by the sealing ring to ensure that the sealing face matches the sealing surface. In this way, very little pressure is needed to compact the cover. With the reduction of the required pressure, the size and number of bolts can be reduced accordingly, so a new product has been designed that is small in size and light in weight (70% ~ 80% less than the weight of the traditional flange). Therefore, flat welding flange type is a better flange product, reduce the quality and space, for industrial use plays an important role.
