Threaded coupling

Couplings are basic fittings used to join, extend or repair pipe runs. These short pieces, usually with female threads, are widely used in water, gas, steam and chemical lines.

Features

Design

  • A short cylindrical piece of pipe.
  • Usually female-threaded at both ends to join two male-threaded pipes.
  • Materials vary with the application: galvanised steel, stainless steel, PVC, brass, bronze, etc.
  • Threads usually to ISO 7-1 (BSP) or ANSI NPT.

Advantages

  • Easy assembly and dismantling: quick work thanks to the threads.
  • Modularity: pipework can easily be extended or modified.
  • Cost-effective: high functionality at low cost.
  • Wide compatibility: versions for different standards and pipe sizes.

Considerations

  • Choose the material and type to suit the application (e.g. stainless steel for acidic media).
  • Thread type and size must match the standard; a mismatch causes leaks.
  • Seal with PTFE tape or a gasket.
  • Check pressure and temperature limits against the manufacturer's catalogue.
