Stainless steel socket flange
Material: ASTM A182 f304, 304L, F316, 316L, 1Cr18Ni9Ti, 0Cr18Ni9Ti, 321, 18-8； American standard
stainless steel socket flange can be produced in the detailed size range:
ASME B16.5 SW CLASS 150LB
ASME B16.5 SW CLASS 300LB
ASME B16.5 SW CLASS 600LB
ASME B16.5 SW CLASS 1500LB
Sealing surface form: RF, MFM, TG and RJ
The basic shape of the socket flange is the same as that of the flat welding flange with neck, that is, there is a socket hole on the inner hole of the flange, the pipe is inserted into the socket hole and welded, and a circle of weld is welded on the back of the flange. Because there is a gap between the socket flange and the groove, corrosion is easy to occur. If another seam is welded inside, this corrosion can be avoided. The fatigue strength of the socket flange welded on both sides is 5% higher than that of the flat welding flange, but the static strength is the same. When using this kind of socket flange, its inner diameter should be consistent with that of the pipe. Socket flange is only applicable to pipes with nominal diameter less than 150.
