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sealing face.Second, the flange gasket has been replaced by a seal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.
