PN40 White Alloy Steel Pipe Fittings 304 DN20 PN25

Manufacturers direct 304 stainless steel internal thread mouth flat welding flange to figure custom high precision 

Flange features:

Flanges not only save space, reduce weight, more important is to ensure that the joint does not leak, with good sealing performance.The size of the compact flange is reduced by reducing the diameter of the seal, which will reduce the section of the sealing face.Second, the flange gasket has been replaced by a seal ring to ensure that the seal faces the sealing face.As a result, only a small amount of pressure is required to compress the cover tightly.With the reduction of the required pressure, the size and quantity of bolts can be reduced accordingly, so the final design of a small volume and light weight (70% to 80% less than the weight of traditional flanges) of the new product.Therefore, flat welding flange is a relatively perfect flange product, reducing the quality and space, plays an important role in industrial use.However, the main design disadvantage of a flat-welded flange is that it does not guarantee leakage.This is the design disadvantage: the connection is dynamic, and such things as thermal expansion and fluctuating periodic loads can cause movement between the flange faces, affecting the function of the flange, thus compromising the integrity of the flange and eventually causing leakage.No product can be without defects, just try to control the product deficiencies to a minimum, so the company in the production of flat welding flange to improve the performance of the product, make it play the role of DA.
