Fully Welded Body Ball Valve Butt Welded Ends For Oil And Gas
Fully Weld Ball Valve
The fully welded ball valve can be directly buried in the ground, without the need to build a underground valve house reduced the project cost. The length of the valve body and the height of the valve stem can be adjusted according to the construction and design requirements of the pipeline. The occasion with strict request external no leakage for transportation of toxic, harmful, flammable and explosive media, the full weld ball valve avoid the injury of personnel when operating the valve. The fully welded ball valve can be used reliably for a very long time under the condition of normal operation and use of the valve.
Fully welded ball valve means the ball valve is split body designed with the body assembly by full welding. Compared with conventional bolted bonnet body assembly, it has no leak point through bolt connection.The full welded body means the valves is impossible to do disassembly maintenance. So the full weld body ball valves used at underground or buried application where maintenance is not expected such as gas transmission, sub-sea application etc. For use in natural gas, crude oil, refined products transmission lines as well as in many other general industrial and oil& gas applications.
