The production process of titanium tee

Titanium tee is usually made of pure titanium and titanium alloy, which is a common form of pipe connection. Generally, the small-scale tee production process is hydraulic expansion and hot extrusion. Below, we will introduce these two production processes in detail:

pipe tee 1 - The production process of titanium tee

Production of Titanium Tee by Hydraulic Expansion Process

Use the hydraulic convex method to manufacture titanium tee. Place the cut pipe in a hydraulic mold, and fill the pipe with liquid. The hydraulic pressure pushes the pressure in the branch out into the fixed hole of the mold. This method provides a good surface finish. However, this method cannot be used to produce a higher thickness tee.

  1. According to the size of the titanium tee to be prepared, select the titanium tube with the corresponding outer diameter and wall thickness;
  2. Cut the titanium tube to the required length of the finished tee, with a little margin;
  3. Put the titanium tube into the mold, align the center, and fill it with liquid;
  4. The titanium tube is extruded at both ends and formed under pressure;
  5. Heat treatment;
  6. Cut the protruding part in the forming process, clean the inner and outer wall surfaces, machine the bevel at the nozzle, and finally check the appearance.

Production of Titanium Tee by Hot Extrusion Process

Tee with large diameter, thick wall thickness and/or challenging special materials are manufactured using hot extrusion methods, which cannot be manufactured by hydraulic expansion methods. In the hot extrusion method, a pipe with a diameter larger than the size of the finished product is usually used, and the branch outlet is squeezed out of the pipe with the help of an extrusion tool. If necessary, other dimensions of the main body and branches can be adjusted by pressing the mold.
The hot extrusion process involves encapsulating a piece of metal heated to the forging temperature in a cavity called a “container”, one end of the cavity has a mold with an opening in the shape of the required finishing part, and applying it to the metal The pressure passes through the other end of the container. When metal flows plastically under the great pressure used, the metal is forced to pass through the opening of its cross-sectional shape.
Using a tee made of raw materials with a larger diameter than the finished product, the branch outlet is squeezed out of the pipe when the main body is pressed. The wall thickness of the outlet can also be adjusted as needed. It is suitable for special materials with large diameter, thick wall thickness and/or challenging workability, which cannot be manufactured using hydraulic convex methods.
The hot press forming of the tee is to flatten the tube blank larger than the diameter of the tee to the size of the tee diameter, and open a hole in the stretched branch tube; the tube blank is heated, placed in the forming mold, and placed in the tube. The blank is loaded with a die for stretching the branch tube; the blank tube is radially compressed under the action of pressure. During the radial compression, the metal flows in the direction of the branch tube and forms a branch tube under the stretching of the die. The whole process is formed by the radial compression of the tube blank and the stretching process of the branch tube. Different from the hydraulic bulging tee, the metal of the hot-pressed tee branch is compensated by the radial movement of the tube blank, so it is also called the radial compensation process.

Seam titanium tee

For the large diameter, generally Φ133mm and above titanium tee in the production process, because the basic pipe is rarely seamless, or because the cost of seamless pipe is relatively high, welded pipe is used for production, or the plate is cut into two pieces The same corresponding shape is formed by die extrusion (half tees), and the two formed half tees are welded into finished titanium tees. Welded tees are generally suitable for tees with larger diameters and thicker walls. Make.
