Duplex Steel Socket Weld Elbows

Unisteels tube fittings with weld ends allow weld system connection to tubing with the advantage of a leak tight seal that can be disassembled in an otherwise permanently welded system. Weld ends conform to ANSI B31.1 and B31.3 piping codes. Welding precautions: Prior to welding, remove the nut and ferrule. To protect the fitting body threads and seat, cover with a plug or another nut. Position a suitable heat sink to dissipate the heat. Insert the tube until bottomed in the socket, then back out approximately 1/16" before welding.
