National Standard Alloy Socket Welding Flange B564 N08820 10"1500#
Socket Weld Flange
Socket weld flange simplified as SW flange, it has a recessed area (like a shoulder) in the flange bore, this shoulder serves as a guide to set the depth of the pipe that inserted to the flange. Socket welding flange initially designed for high pressure small diameters piping system.
Available Material:
Standard: Carbon steel ASTM A105, ASTM A350 LF1/2, ASTM A181 Alloy steel ASTM A182 F5, F9, F11, F22, F91 Stainless steel ASTM A182 F304/L, F316/L Outer Diameters: 1/2 inch to 24 inch, up to 2500# Special made: 24'' to 60'', up to 900# Wall Thickness: Schedule 40 to 160 Pressure Ratings: Class 150 to Class 2500 Face Type: RF, RTJ
How to Use
Insert the pipe end into socket weld flange, until the pipe bottom touch the shoulder area, pull back 1.6mm (1/16'') distance of the inserted pipe then do fillet welding. The point is to create a expansion gap (1 fillet weld) between the flange and the pipes or fittings.
How is Socket Welding Flange Generated
The socket welding flange was firstly to use for stainless steel superheater, due to avoid cracking defects caused by thermal stresses in heating processes, and after years development it became a standard applications for all types of material.
Advantages
Socket weld flange could replace threaded flange, to minimize the risky of leakage.
No need to beveling before welding.
Welding work outside of the pipe, will not penetrate the pipe
Materials
Carbon Steel: ASTM A105. ASTM A350 LF1. LF2, CL1/CL2, A234, S235JRG2, P245GH P250GH, P280GHM 16MN, 20MN ,20# and so on. Stainless Steel: ASTM A182, F304/304L, F316/316L and so on. Alloy Steel: A182 F11, A182F22, A182F12, A182 F5, A182F91, A182 F9 and so on.
