The black steel tee provides a three-way carbon-steel connection without a galvanized surface. Equal and reducing versions join compatible pipe through butt-weld ends. Its black or agreed rust-preventive finish leaves the final surface-treatment route linked to the spool fabrication plan. Two ends carry the main run, and the outlet forms a branch for a utility or process connection. The steel grade, wall schedule and size combination establish the purchased fitting. After welding and the required surface preparation, the assembled pipework can receive its specified coating. The fitting therefore needs to be selected with both the service and the fabrication sequence in view.

Main Applications
The black steel tee branches compatible water, air and plant utility lines.
Workshop spools around pumps and skids can receive a coordinated coating after assembly.
Maintenance extensions can match an existing ungalvanized carbon-steel arrangement.
Preparing a spool before applying its finish keeps the fitting and adjoining pipe surfaces within the same coating operation.
Why choose us
We manufacture black steel tee with the surface condition linked to the intended fabrication route. Branch geometry, steel grade and wall schedule are checked for each size group. Mixed items can be separated during packing so workshop teams can identify the required fittings. This order control is useful for spool packages containing several similar tees that will receive their final coating after assembly.
Where the completed spool will be coated, include the required delivery surface condition so temporary protection and later preparation are understood before dispatch.
FAQ
Q: Does black steel mean a zinc-coated surface?
A: No. It describes an ungalvanized carbon-steel fitting.
Q: Can the outlet be smaller than the run?
A: Yes. Reducing versions provide a smaller branch connection.
Q: Can the completed spool receive a coating?
A: Yes. The specified finish can follow welding and surface preparation.
