What is the minimum gap allowed for a socket weld fitting?

1/16th”
The 1/16th” gap for socket welds is accepted as an ASME standard because it is proven to limit cracked socket welds.

What is socket weld fittings?

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.

What type of weld is a socket weld?

Socket weld (the fillet weld) resists around 1/2 the strength of butt welding. So it is mainly used for small pipeline (Small Bore Piping) with diameters NPS 2 or smaller. Butt weld keeps better strength, good for high pressure or high temperature pipelines.

Do socket weld fittings have a schedule?

Socket weld fitting comes in a pressure rating of 3000 pound, 6000 pound, 9000 pound. Loosely, they are related to 3000 pound is roughly schedule 80, extra heavy; the 6000 pound is roughly schedule 160. Socket weld fittings are available from 1/2 inch all the way to 4 inch nominal pipe size.

What are different types of pipe fittings?

Types of pipe fittings and their purposes:

Elbows: Used to change the angle or direction of the pipe run.
Street Elbows: One end of the pipe fitting has male threads and the other end has female threads.
Tee Fittings: Shaped like the letter T.
Couplings: Used to join two straight pieces of pipe of the same diameter.

How do you determine root gap in welding?

The plate edges must be tightly butted (1/32-in. maximum gap) as with the square butt joint. When the welding composition is retained by a support below the joint, slightly greater root gaps are permissible; if the root gap exceeds 1/16- in., submerged arc welding flux should be tamped into the gap ahead of the weld.

Can you XRAY socket welds?

The answer to your question is “NO” because radiographic test can be used on socket welds.

What is fitting and its types?

Fittings are generally used in mechanical and plumbing operations for a number of different purposes. There are many different kinds of fittings, made from a variety of materials: some of the most common types are elbows, tees, wyes, crosses, couplings, unions, compression fittings, caps, plugs and valves.

What are the two types of pipe connections?

Generally there are two types of couplings are available. Compression coupling and slip coupling. Compression coupling is regular coupling which is connected between two pipes and it prevents leakage by the arrangement of gaskets or rubber seals on both sides, otherwise glue is provided.

What are the differences between socket weld and butt weld?

A butt weld is where the diameter of the pipes welded together are the same, a socket weld is where a larger diameter pipe is fitted into a smaller one. In making a butt weld, the pipes (or pipe and fitting) usually have an angle machined or ground into the outside corner,…

What are the dimensions of PVC fittings?

It is available in several standard sizes, ranging from ½ inch (1.3 centimeters) to 4 inches (10.2 centimeters) in diameter. PVC pipe is only made to handle cold water, as hot water will cause the pipe to warp.

What are socket pipe fittings?

A Socket Weld Fitting 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 4 or smaller.
