A tube socket weld (TSW) connector joins instrumentation tubing to a threaded port using a welded joint on the tube side. The tube is pushed into a counterbored socket and fillet welded around its outside, giving a permanent connection with no ferrules or nut. The other end carries an NPT thread for connection to a valve, instrument or manifold.
Socket welding is often specified where mechanical tube joints are not wanted, such as on lines subject to heavy vibration, thermal cycling or where the design code calls for welded connections. It is also used to reduce the number of potential leak points in a long run. The male connector screws into a female NPT port; the female connector accepts a male NPT component such as a nipple or gauge stem.
These connectors are SS316 and cover tube sizes from 1/8" to 2" and 6 mm to 38 mm. Leave a small gap between the tube end and the bottom of the socket before welding, which allows for thermal expansion and reduces the risk of cracking at the root, as is standard practice for socket welds.
