Union Pipe Fittings - The Flexible Connection for Pipe Systems

Union pipe fittings play a pivotal role in joining and disconnecting pipes and tubes across various systems. Unions create leakproof yet detachable joints that prove helpful during transport, installation, maintenance, or for isolation purposes. With threads on both sides of an interchangeable centerpiece, unions connect pipes that can later separate without damage or leaks occurring. The union fitting acts as an intermediate coupler between two pipe sections, allowing them to be conveniently uncoupled as needed.

Union joints give your pipe network the flexibility for fluid flow control, equipment removal, spatial adjustments, repairs, and redirection. Typical uses include connecting domestic water lines, fuel transfer pipes, compressed air setups, gas piping, fire systems, and industrial/commercial plumbing.


Types of Union in Plumbing Based on Usage and Assembly Method

There are several union variants designed for specific applications and joining techniques:


Standard Screwed Union

  • Have tapered threaded male connections on both ends with flat seating surfaces.
  • Connect via threading into female threaded pipe openings. Compression of the seal occurs when tightened.
  • Allow quick, tool-assisted assembly and disassembly of small-bore pipe joints up to 4 inches.
  • Suited for low to medium-pressure installations. Common for water lines, fuel transfer pipes, etc needing occasional detachment.


Ground Joint Union

  • Feature spherical ground mating surfaces between end pieces and the center ring.
  • When tightened, the spherical seal self-aligns to create a leakproof fit for the life of the system.
  • No need for seal replacements or joint re-tightening. Long-term reliability.
  • Handles high temperatures and pressures. Usage in steam lines, chemical transport, etc.


Flange Union

  • Uses flange connections instead of threads to join pipes.
  • Flanges bolt together with a gasket in between to form the seal.
  • Quick connect/disconnect of large diameter pipes over 4 inches in size.
  • Allows precision alignment of heavy pipe sections. Common in chemical plants, refrigeration systems, etc.


Swivel Joint Unions

  • Have a rotating center section to prevent hose twisting.
  • The fixed female threaded ends eliminate leverage stress on the hoses or pipes attached.
  • Often found connecting hydraulic hoses, liquefied petroleum gas lines, sulfuric acid piping and other flexible industrial tubes requiring movement.


Dresser Style Union

  • Uses a sleeve coupling over the raised face flanges with a hidden gasket.
  • The sleeve nut tightens the unit via torque-limiting screws around the center.
  • Allows very rapid connection and disconnect without gasket handling.
  • Facilitates inspection and maintenance in oil refineries, power plants, and other large piping networks.


Factors to Consider When Selecting Your Pipe Unions

Choosing suitable union fittings for your piping application requires assessing:

Installation Position

  • Whether the union will work vertically overhead or lie horizontal changes options. Consider gravity effects.


Operating Temperature

  • Heat capability varies based on materials like plastic, brass, and steel. Ensure union rating exceeds system temperatures.


Operating Pressure

  • Union pressure handling ability depends on size, materials, and tightness. Confirm sealing capacity meets your needs.


Pipe Material & Size Match

  • Select union fittings that directly match your existing pipe material and diameter for proper mating and sealing.


Application Environment

  • Fluid properties and exposure conditions factor in. Specify corrosion and chemical resistance needed.


Frequency Of Disassembly

  • More demanding detachment needs may dictate heavier-duty mechanical unions or added units per system length.


Ease Of Assembly

  • Threaded and flanged types strike a balance of secure sealing and reasonable human assembly, but power tools could assist.


Leakproof Reliability

  • Ground joint and compression union types offer enhanced sealing while threaded can loosen over time. Weigh tradeoffs.


Trusted Suppliers

  • Reputable manufacturers have stringent quality control and use certified raw materials for safety.
