What Is A Welded Joint Valve?

Welded joint valve refers to the valve body with welded groove, welded with the pipe connection valve. Welded joint valves are divided into two types in the structure of butt welding and socket welding, usually by butt welding. This valve is mainly used for the connection of the pipeline system, which is characterized by strong connection, good sealing, and not easy to leak.

When selecting and using welded joint valves, the following points need to be considered:

Determine the valve specifications and models, according to the pipeline system pressure, temperature, media and other parameters to choose;

Check the appearance quality of the valve before installation to see if there are defects such as damage or cracks;

During installation, it is necessary to pay attention to the selection of welding process and welding materials to ensure welding quality;

In the process of use, it is necessary to regularly check the sealing performance of the valve and the flexibility of the valve stem, and if there is a problem, it should be repaired or replaced in time.

Welded joint valves are usually used in high-pressure systems of ships, such as fuel supply systems, hydraulic control systems, etc. These systems need to withstand high pressure, and need to ensure a strong connection and seal reliability, so welded joint valves are widely used in these systems.

In addition, on some special purpose ships, such as liquefied natural gas carriers, deep-sea detectors, etc., it is also necessary to use welded joint valves to meet special needs. For example, the liquid cargo tanks of liquefied natural gas carriers need to use welded joint valves to ensure tightness, and the pipeline systems of deep-sea detectors need to use welded joint valves to connect various sensors and actuators.
