Valve connection to the pipe can be removable or welded.

Welded end conncections are quiet common in high pressure and high temperature fluid applications. Particulary in steam and water service in power plants.

Care must be exercised when welding valve bodies in the pipeline to prevent excessive heat transmitted to valve trim parts. Trims with low-temperature composition materials must be removed before welding.
