Usage: Used for cross-branch connection of pipelines. Reducing means the branch or main pipe is reduced in diameter.
Additional Note:
Installation positioning requires higher requirements to ensure that the pipes in four directions are aligned.
The welding sequence is more complicated and requires careful planning. Usually a symmetrical welding sequence is adopted, and temporary support and fixation are done to prevent displacement and deformation due to gravity or stress. The operation difficulty and risk are higher than that of a tee.
Reducing cross: Be sure to know the size of each port.
