Application And Development Of Titanium Pipe Fittings

Application and Development of Titanium Pipe Fittings

The standardized production of titanium pipe fittings is also a revolution in the application of titanium pipes in recent years, which greatly improves the life of titanium pipes and advances the application of titanium. This paper introduces the advanced technology of elbow production --- elbow pushing process, the titanium elbow produced by this process can ensure uniform wall thickness. The birth and development of titanium pipe fitting standards at home and abroad, as well as the production and standardization of titanium pipe fittings in my country are introduced.

Comparison of production technology of titanium pipe fittings

In the 1970s, titanium was used in the chemical system of the civil industry. As a corrosion-resistant structural material used in chemical plants, titanium has established its position and is an ideal material for chemical transportation of corrosive media. The life of the pipeline depends on the pipe fittings, and the titanium pipe fittings are also attracting more and more attention of the engineers and technicians, especially the standardization of the titanium pipe fittings is more important.

1.1 Working conditions of titanium pipe fittings First, let's analyze the working conditions of titanium pipe fittings:

Titanium pipelines mainly transport corrosive and dangerous medium. When the corrosive medium passes through the titanium pipe fittings, the medium has a certain pressure, and the bearing pressure of each part of various pipe fittings is different. The most commonly used three pipe fittings (elbow , tee, reducer) to analyze.

1.1.1 Elbow

Elbow is one of the important pipe fittings in the middle pipeline system. In addition to changing the flow direction of the medium, it also improves the flexibility of the pipeline. When the medium passes through the elbow, the medium with pressure goes straight to the back of the elbow, and the medium flows along the back to the outlet. It can be seen that the back of the elbow is subjected to both high pressure and severe erosion and corrosion, indicating that the back is bearing larger than any part.

1.1.2 Tee

The working condition of the tee is similar to that of the elbow. When the medium passes through the tee, it rushes straight to the intersection of the branch of the tee and the straight path, where the bearing pressure and erosion corrosion are greater than other parts. The branch is the pressure relief and branch state of the main pipeline.

1.1.3 Reducer

The working condition of the reducer, when the medium passes through the reducer, the medium tends to flow from the large end to the small end. Due to the gradual reduction of the cross-sectional area, the vertebral body of the reducer is pressurized, and the inner surface of the vertebral body has a higher bearing capacity. High pressure and severe erosion corrosion.

The above analysis shows that titanium pipe fittings are extremely important components in titanium pipes, which directly affect the life of titanium pipes.
