Difference Between Socket Weld And Butt Weld Valve End Connections

  • Socket Weld Valve End Connections – These types of connections are socketed so as to have a plain spigot end of the pipe. These are used on valves that are made up of steel, and for such applications that require higher pressure and/or higher temperature in pipelines that do not necessitate repeated disassembling.
  • Butt Weld Valve End Connections – These types of end connections are manufactured in such a manner that each end of the valve is bevelled to match with the thickness and bevel on the pipe.   After this, the two ends are butted to the pipeline and are welded.

 

benefits of Butt Weld End Ball Valve

  • Stem seal: Viton O-rings; Expanded graphite ring for fire safe
  • No Cavity: There is no cavity to allow build-up of solids
  • In-line servicing: Allows quick and easy in-line seat inspection or replacement within minutes
  • Double offset: Ensures a progressive smooth and low friction seat-disc closing. Hardened sealing surface to provide high level of tightness and long lifetime
  • Fire safe design: All metal construction providing inherent fire safe
  • Unique sealing system: Combined with the eccentric disc rotation, the patented flexible metallic seat provides an exceptional tight shutoff even with high temperature fluctuations
  • Actuators: Pneumatic, hydraulic, electric or manual gear; fast acting actuators for Emergency Shut Down (ESD) function
  • Extended bonnet: With a sufficient gas column to keep the stem packing away from the cold fluid
  • High quality castings: With X-ray and PT examinations from approved foundries
  • Stainless steel shaft bearings: Coated with nickel-reinforced PTFE for high cycle and smooth operation
  • Reliability: Reliability of valve operation affects service life and ease of inspection and maintenance. In order to predict reliability, a sound valve design must be backed up by a stress analysis and functional qualification testing under critical operating conditions.
