How are reducing tee pipe fittings manufactured?

Aug. 12, 2026

There are various methods for manufacturing reducing tee fittings. Let us examine a few of them:

1) Hydraulic Bulging Method

The hydraulic bulging method is used to manufacture tees. A cut length of pipe is placed into a hydraulic mold, and liquid is injected into the interior; the hydraulic pressure forces the pipe material out through a fixed opening in the mold. This method yields a high-quality surface finish. However, it is not suitable for manufacturing tees with thick walls.

2) Hot Extrusion Method

Hot extrusion is typically employed for tees that cannot be produced via hydraulic bulging—specifically those with large diameters, thick walls, or those made from special materials that are difficult to process. In this process, a pipe with a diameter larger than the finished product's dimensions is used, and the branch outlet is extruded from the pipe body using an extrusion die. If necessary, additional dimensions of the main body and the branch can be adjusted using a forming die.

Advantages of seamless carbon steel elbows

The raw material for seamless carbon steel elbows is seamless steel pipe. The main production process involves heating and piercing a round tube billet, then rolling it using three-roll cross rolling, continuous rolling, or extrusion to set (or reduce) the outer diameter of the pipe. After cooling, it is straightened. It undergoes direct hydrostatic testing (or flaw detection), is marked, and then stored. Schxx represents the wall thickness grade; 180e (S) indicates a short-radius 180° carbon steel elbow, and 180e (L) indicates a long-radius 180° elbow; 90E (S) indicates a short-radius 90° carbon steel elbow, and 90e (L) indicates a long-radius 90° elbow; 45
