China stainless steel 304H Blind flanges Manufacturers, Suppliers, Factory

Duplex steel S31803 threaded flanges is a kind of flange connected with the pipe by the thread. Design, according to the loose flange treatment. The advantage is that there is no need to weld, flange deformation on the cylinder or pipe generated additional torque is small. The disadvantage is that the flange thickness is large and the cost is high. Suitable for high pressure pipeline connection.

Socket Pipe Fitting are mainly divided into high pressure pipe connecting accessories which are formed by round steel or steel ingot moulded blank and then machined by lathe, and pp resin modified polypropylene low pressure pipe which is connected by flexural double melting tube fittings.

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 Secondly, the flange gasket has been replaced by the sealing ring to ensure that the sealing face matches the sealing surface.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.
