Problems solved by technology

If only thin-walled titanium tubes are welded into a tee pipe, since the confluence area of ​​the tee is most severely eroded by the liquid, the weld seam has low erosion resistance and is easy to break, and its service life is not advantageous.

Embodiment 1

[0024] Depend on figure 1 , figure 2 As can be known, a kind of production method of titanium tee pipe, it comprises the following steps:

[0025] (1) Blank tube: use pure titanium to process the blank tube in the tube end shaping machine as the main tube 1;

[0026] (2) Cold expansion forming: place the main pipe 1 obtained in step (1) in the mold of the pipe end shaping machine, press the set point on the main pipe 1 under normal temperature conditions, and squeeze out the prototype bubble from the inside to the outside of the pipe wall;

[0027] (3) Hole opening: Cut the top of the prototype bubble in a direction parallel to the central axis of the main pipe 1 to form a branch pipe connected to the main pipe 1;

[0028] ⑷Secondary molding: use the method of step 2 again to expand the opening of the branch pipe blank to the required set size, and adjust the angle of the branch pipe blank at the same time;

[0029] ⑸Reshaping: Trimming the opening of the branch pipe bille...

Embodiment 2

[0038] The thickness of the main pipe 1, the branch pipe 2 and the side pipe 3 in this embodiment is 1.0mm, and the outer diameter is 50.8mm.

[0039] The rest are the same as embodiment 1.

Embodiment 3

[0041] The thickness of the main pipe 1, the branch pipe 2 and the side pipe 3 in this embodiment is 0.75 mm, and the outer diameter is 40.0 mm.

[0042] The rest are the same as embodiment 1.

Abstract

The invention discloses a production method of a titanium three-way tube which is applied to the water conveying environment. The production method comprises the steps of billet tube manufacturing, cold expanding forming, hole punching, second time of forming, shaping, side pipe connecting and connector installing. The titanium three-way tube comprises a main tube, a branch tube is installed on the main pipe, a side tube is welded to an opening of the branch tube, a tube connector is installed at the tube end of the side tube. The titanium three-way tube is a thin-walled three-way tube made through cold machining forming of a pure-titanium tube, all aspects of excellent performance of corrosion resistance, low density, high specific strength and the like of titanium materials is kept, the technical problem that a welding joint cannot be arranged in a liquid junction is solved, connection through a non-three-way mode such as welding through flange discs is avoided, titanium flange type connectors are arranged at the tube ends, direct connection of a water conveying pipeline is achieved, liquid conveying resistance is small, the occupied space is small, the overall weight is small, water conveying efficiency is high, installing is efficient, fast and convenient, maintaining is convenient, cost is low, and the titanium three-way tube can be widely applied to the water conveying environment.

Description

technical field [0001] The invention relates to a pipe fitting, in particular to a titanium pipe fitting, in particular to a titanium tee pipe and a production method thereof. Background technique [0002] The hardness of titanium is about the same as that of steel, but its weight is only half that of steel of the same volume. Although titanium is slightly heavier than aluminum, its hardness is twice as strong as aluminum. In space rockets and missiles, titanium is widely used instead of steel. Titanium can be alloyed with other elements such as iron, aluminum, vanadium or molybdenum to produce high-strength light alloys, which are widely used in various fields, including aerospace (jet engines, missiles and spacecraft), military, industrial procedures ( Chemicals and petroleum products, seawater desalination and papermaking), automobiles, agricultural products, medicine (prosthetics, orthopedic implants and dental instruments and fillings), sporting goods, jewelry and mobi...
