Table E Flange Dimensions

/ / Published in INDUSTRY NEWS

Table e flange is used in the connection between chemical, construction, water supply, drainage, oil and gas, light industry and heavy industry, refrigeration, sanitation, pipeline, fire, electrical, aerospace, shipbuilding and other infrastructure projects.
1) Type: Welding Neck(WN), Plate(PL), Slip On(SO), Blind(BL), Socket Welding(SW), Threaded(TH), Lap Joint(LJ), Long Welding Neck(LWN)
2) Widely Used Material For ASME B16.5 LJ RF Flange
Stainless Steel: A182 F304/310/316/317/321/347
Carbon Steel: A105
Alloy Steel: A182 F5/F9/F11/F22/F51/F53 INCONEL600 625 825
3) Flanges are commonly used to connect valves into pipework making it easier for removal and maintenance. There are many common flange standards and flanges within the same standard can etiher be flat (commonly cast iron, ductile iron) or raised face (commonly cast steel and stainless steel).
4)Below is a reference table for critical flange dimensions to help identify what standard you have.
