The role of titanium pipe fittings in the chemical industry

My country began to use titanium in the chemical system of civil industry in the 1970s. As a corrosion-resistant structural material used in chemical equipment, titanium has established its position, and as an ideal material in chemical pipelines for transporting corrosive media, The life of the pipe depends on the pipe fittings, and the titanium parts have attracted more and more attention from engineers and technicians, so the standardization of titanium pipes is more important.

Let's analyze the working conditions of titanium parts: titanium pipes mainly transport severely corrosive and dangerous media. When the medium with corrosive media passes through titanium pipe fittings, the medium has some pressure, and the bearing pressure of each pipe fitting is different. Three commonly used pipe fittings (elbow, tee, reducer) to analyze:

1. Titanium reducer:
The working conditions of the reducer, when the medium passes through the reducer, the medium often flows from the large end to the small end. Due to the gradual reduction of the cross-sectional area, the cone of the reducer will be pressurized, and the inner surface of the cone will carry more pressure. High pressure and severe erosion corrosion.

2. Titanium elbow:
Elbow is one of the important pipe fittings of each pipeline system. In addition to changing the flow direction of the medium, it also increases the flexibility of the pipeline. When the medium passes through the elbow, the medium with pressure rushes 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 bears both high pressure and severe erosion and corrosion, indicating that its The back bears more weight than either part.

3. Titanium Tee:
The working condition of the tee is similar to that of the elbow. When the medium passes through the tee, it will go straight to the intersection of the branch of the two-way and the straight road. The bearing pressure and erosion corrosion here are greater than those of other parts. The branch is the state of pressure relief and diversion of the main line. .

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