Production Process Overview

Titanium tees and crosses can be produced through three main forming methods, depending on size, wall thickness, and material grade.

1. Hydraulic Bulging (For Small Seamless Tees)

Suitable for small-size and thin-wall seamless tees.

Process:

1. A cut pipe section is placed inside a hydraulic mold.

2. The pipe is filled with liquid.

3. Hydraulic pressure expands the material outward through the branch outlet cavity in the mold.

Advantages:

Extremely smooth surface finish

Good dimensional accuracy

Uniform wall thickness

2. Hot Extrusion (For Large/Thick/Special Material Tees)

Used when hydraulic bulging is not possible—especially for:

Large diameters

Thick wall tees

High-strength or special alloys

Process:

1. A pipe with a larger diameter than the finished product is used.

2. Heated to elevated temperatures.

3. Extrusion tools apply force to push out the branch outlet.

Advantages:

Suitable for difficult-to-form titanium alloys

Accurate forming for heavy-wall fittings

High structural integrity

3. Butt Welding (For Large-Diameter Tees, Typically OD ≥ 133 mm)

Used when:

Seamless pipe is unavailable in required size

Seamless pipe cost is too high

Very large-diameter tees/crosses are needed

Process:

1. Plates are cut into two matching half-tee shapes.

2. The halves are pressed in a mold.

3. The two formed halves are welded together to create the final tee.

Advantages:

Cost-effective for large diameters

Allows custom sizes

Suitable when seamless titanium is limited
