What is socket weld pipe?
A Socket Weld is a pipe attachment detail in which a pipe is inserted into a recessed area of a Valve, fitting or flange. In contrast to buttweld fittings, Socket Weld fittings are mainly used for small pipe diameters (Small Bore Piping); generally for piping whose nominal diameter is NPS 2 or smaller.
How do you weld a socket welding valve?
The socket welding ends are prepared by boring in each end of the valve a socket with an inside diameter slightly larger than the pipe outside diameter. The pipe slips into the socket where it butts against a shoulder and then joins to the valve with a fillet weld.
What is Silbraze?
Bronze-silver braze (or sil-brazed) fittings are made of ASTM B-61 or B-62 bronze and are constructed with a pipe-sized end socket with precision groove for silver ring insert. Absence of threads means that there is no reduction of strength at the joint and that thin-wall pipe may be used.
Can you XRAY socket welds?
The answer to your question is “NO” because radiographic test can be used on socket welds.
Is a socket weld a fillet weld?
Socket weld(SW) is the welding method of pipeline insertion.It is welded two different sized pieces of pipe,the smaller one is inserted into the large one. The weld is completely in the periphery of the large pipe and it is fillet weld.
What is an NPT valve?
NPT: This is a threaded connection. In fact, the acronym, NPT, stands for National Pipe Thread Taper. This is a United States standard for all piping and valve threads. Unlike the threading found on a typical bolt, which is straight, tapered threads will actually pull the valve tighter to the pipe during installation.
What is better butt weld or socket weld?
Socket weld is troublesome in corrosive fluid service due to crevice corrosion. Butt weld is the “best” in terms of strength, fatigue, and corrosion resistance, and temperatures compliance. However, it is more difficult to fit-up and weld properly, needing skilled welder and much time.
