Cross
A pipe cross is a kind of pipe fitting that be used in the place where four pipes meet together. Cross Fitting type: weld on cross, Material: Carbon Steel per ASTM SA-234 Grade B, Dimensions conform to ASME B16.9,The pipe cross may have one inlet and three outlets, or there inlets and one outlet. The diameter of the outlet and inlet can be the same and can also be different. That is to say, straight cross and reducing cross are both availabe.

Common types of pipe tee
A pipe tee is a type of fitting that has a T shape and is used to join two or more plumbing pipes.
- Equre tee (or straight tee), means the branch diameter of this tee is same with the main pipe (Run pipe) diameter of this tee.
- Reducing tee is a type of pipe fitting in which the branch port size is smaller than the ports of the run.
- Barred tee is used in pipelines that are pigged.
- Lateral tee has a 45 degree branch from a pipeline.
- Pipe cross is a fitting that used in the place where four pipes meet with the same diameter include:
- Reducing cross used for connecting four pipes, the main pipes with the same size, but the dimensions of the branch diameter is smaller than the main pipes.
- Equal cross in the place where four pipes meet with the same diameter.
- Forged Tee Fittings are pipe fittings that be formed mainly by forging.
