Usage: Used for pipe branch connection. Reducing means the branch or main pipe is reduced in diameter. Saddle tees need to be installed on the main pipe.
Additional Note:
Reducing Tees: Be sure to distinguish the main pipe from the branch pipe, the large diameter end from the small diameter end, and confirm the flow direction. Whether to install the large end or the small end first during welding depends on the site conditions, but the operating space and socket depth must be guaranteed.

Tees (reducing):
Holes need to be opened on the installed main pipe. Special saddle drilling tools must be used to ensure that the hole size is accurate and the edges are flat and smooth.
The opening area must be thoroughly cleaned.
The contact surface between the saddle fitting and the main pipe must be clean and dry. The welding process (heating, socketing, pressure-maintaining cooling) must be particularly stable to ensure that the saddle and the main pipe are completely fitted and melted. High requirements for operating technology and equipment stability.
Socket hot-melt tee: The socket order of the three ports must be considered during installation. Usually, the two ends of the main pipe are installed first, and the branch pipe is installed last. Pay attention to the direction of the branch pipe. Large diameter tee welding requires stable support.
