Socket Weld Fittings at Hy-Lok Canada

Socket Weld Fittings

Socket weld fittings are a vital component when it comes to maintaining and extending your pipelines by allowing you to extend your line permanently. Once in place, socket weld fittings help to increase your fluid control, as well as transfer efficiency. Socket welds are inserted into recessed areas of a valve, fitting, or flange, typically on small diameter pipes with a nominal diameter of NPS2 or smaller. Hy-Lok Canada is a leading manufacturer and supplier of these fittings throughout the nation, and maintains a robust inventory of fluid system components for clients spanning the aerospace, petrochemical, oil & gas, biotech, and natural gas industries.

What Are Socket Weld Fittings

As mentioned above, socket weld fittings refer to a type of fitting wherein piping is attached to part of a flange, fitting, or valve. Socket weld fittings help to maintain high strength connections and are designed to adhere to ASME B16.11 which covers the ratings for tolerances, temperatures, pressures, and handles various material specifications.

Socket weld fittings are available in a wide range of components, including weld elbows, weld tees, reducing tees, couplings, flanges, and more.


Socket weld fittings have a wide range of benefits and can be particularly helpful within instrumentation systems that involve the flow of fluids and gasses and require precision. Advantages include:

  • No need to bevel the pipe for weld preparation
  • Temporary tack welding is not needed for alignment
  • Weld material cannot penetrate into the bore of the pipe
  • Can be used in place of threaded fittings, making the risk of leakage significantly lower
  • Construction costs are lower than with butt-welded joints due to the lack of exacting fit-up requirements and lack of need for the special machining required for butt end weld preparation.

In addition, socket weld tube fittings are suited to a wide range of applications and can often be used in high-pressure applications and industrial settings. Socket weld fittings may be used for the safe conveying of toxic or flammable materials where leakage can be extremely detrimental to the overall system.
