Socket weld union coupling dimensions is designed manufactured according to MSS SP-83 standard, the weight is more heavier becuase it consists of three parts that a male end, a nut famale end. The joint can be disassembled as a pipe fitting, the things connected through the joint can be disassembled replaced.
MSS SP 83 socket weld union size range is 1/8" to 3" pressure rating is available in Class 3000 / 6000 lbs.
Socket Weld Fittings are a family of high pressure forging fittings that used only in conjunction with ANSI Pipe are available in the same size range. Even though there are some similarities between the shapes of the two welds, but socket weld is still considered to be different a fillet weld.

MSS SP 83 Socket Weld Union Coupling Dimensions
1) The even thickness around the socket bore shall be less than the average value, the thickness at partial areas can be the min. one.
2) Considering the tolerance of outside diameter of pipe, the diameters of some socket bore can be a little larger than the ones specified in B16.11.
3) When the sizes of the connecting pipes are conformed to the ones specified in this catalog, the sizes of the connecting pipes shall be provided in the purchase specification.
4) When the fittings are reducing,the structure sizes shall be same as the ones of the straight fittings B J D shall be machined per the according reducing ends.
5) Fittings can also be manufactured as the mixed connectings of SW THRD.
