ASTM A234,A420,A403,A860 Tee Fittings are connectors used at branch points in pipeline systems, featuring three ports (one inlet with two outlets or two inlets with one outlet). They are classified by diameter into equal tees (same size) and reducing tees (different sizes), and by branch morphology into T-shaped tees (straight tee) and Y-shaped tees (lateral tee).
Materials include stainless steel, carbon steel, copper, plastic, and over ten other options, catering to industries such as chemical, construction, oil, gas, and marine engineering. Connection methods encompass butt-weld, socket-weld, and threaded types, complying with standards like GB, ASME, and DIN.

Manufacturing Process of Tee Fittings
- Raw Material Preparation:
Select suitable pipe materials or steel billets based on the required material of the fittings, ensuring raw material quality meets standards.
- Heating Treatment:
Heat the raw materials to an appropriate temperature to achieve good plasticity for subsequent processing.
- Forming Process:
Use equipment such as hydraulic presses to shape the heated material into a tee via molds, controlling pressure and speed to ensure forming quality.
- Trimming & Machining:
Trim the preliminary-formed tee, remove excess material, and machine the inner/outer walls to ensure dimensional accuracy and surface smoothness.
- Heat Treatment:
Apply processes like quenching and tempering to improve the microstructure, enhancing strength and toughness.
- Quality Inspection:
Perform visual, dimensional, and non-destructive testing (e.g., ultrasonic or magnetic particle inspection) to ensure compliance with standards.
- Surface Treatment:
Apply treatments such as galvanizing or painting as needed to enhance corrosion resistance.
- Packaging & Storage:
After passing inspection, package the tee fittings and store them for dispatch.
