Applicable Principles and Use of Brass Ball Valves

Ⅰ. What aspects are brass ball valves suitable for?

1. For the main pipelines of oil and natural gas, the pipelines that need to be cleaned, and those that need to be buried in the ground, the ball valves with all-passage and all-welded structure are selected.

2. For those buried in the ground, choose a ball valve with full-pass welding connection or flange connection; for branch pipes, choose a ball valve with flange connection, welding connection, full-pass or reduced diameter.

3. Flanged bronze ball valve and brass ball valve are selected for the pipelines and storage equipment of refined oil.

4. On the pipelines of city gas and natural gas, use a floating ball valve with flange connection and internal thread connection.

5. In the oxygen pipeline system in the metallurgical system, it is advisable to use a fixed ball valve that has undergone strict degreasing treatment and is flanged.

6. In the pipeline system and device of low temperature medium, the low temperature ball valve with valve cover should be selected.

7. On the pipeline system of the catalytic cracking unit of the oil refining unit, the lifting rod type ball valve can be selected.

8. In the devices and pipeline systems of corrosive media such as acid and alkali in chemical systems, all stainless steel ball valves made of austenitic stainless steel and PTFE as the valve seat sealing ring should be selected.

9. Metal-to-metal sealing ball valves can be used in the pipeline systems or devices of high-temperature media in metallurgical systems, power systems, petrochemical plants, and urban heating systems.

10. When flow adjustment is required, a worm gear driven, pneumatic or electric regulating ball valve with V-shaped opening can be selected.

Ⅱ. Brass ball valves are widely used

The use of OEM ball valve is very extensive, the variety and quantity of use are still expanding, and they are developing towards high pressure, high temperature, large diameter, high sealing, long life, excellent adjustment performance and multi-function of one valve. Its reliability and other performance indicators All have reached a high level, and have partially replaced gate valves, globe valves, and regulating valves.

With the technological advancement of ball valves, there will be more extensive applications in oil and gas pipelines, cracking units in oil refining and in the nuclear industry in a foreseeable period of time. In addition, ball brass valves will also become one of the dominant valve types in the fields of large and medium calibers and medium and low pressures in other industries.

In order to improve efficiency, our general manager found the most suitable assembly method after months of research, namely Uline. The application saves 3 to 6 labors per assembly line. Each worker assembles the finished product rhythmically, greatly improving production efficiency. Welcome to consult.
