Socket Weld Cross
Socket weld cross is also called socket weld four-way fitting that used to make three 90 degree branches from main run pipeline. Both equal and reducing crosses are in various size, dimensions and material. The Socket Weld Fittings Section is designed to hold the various sizes of the pipes it has to be attached to.
Socket Weld Fittings are a family of high pressure forging fittings that used only in conjunction with ANSI Pipe and 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 from a fillet weld.

1) The even thickness around the socket bore shall not 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 aren t 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 and B J D shall be machined per the according reducing ends.
5) Fittings can also be manufactured as the mixed connectings of SW and THRD.
