Key Features of UPVC Union for Industry

  • Detachable connection: has three parts; loosen the nut to separate pipes.
  • Solvent cement joint: both end bodies are permanently bonded to pipes.
  • O-ring seal: the internal O-ring provides reliable, corrosion-resistant sealing.
  • Easy maintenance: solves rotation issues in long or complex pipe runs.

Manufacturing Process of UPVC Union for Industry

Each consists of three main components injection molded from UPVC. The O-ring groove is precision machined, and seals are EPDM or FPM for chemical resistance.

Critical Process Parameters of UPVC Union for Industry

Every is checked against these parameters:

  • Control of thread fit accuracy between body and locking nut.
  • Precise machining of O-ring groove dimensions for proper seal compression.
  • Precise machining of socket ID, ovality, and chamfer on both ends.

Raw Material Characteristics of UPVC Union for Industry

  • Body and nut: UPVC (PVC-C version available for high-temperature use)
  • The fitting Seals: EPDM or FPM (fluoroelastomer)
  • UPVC suitable up to 60°C; PVC-C suitable up to 93°C
  • EPDM resists acids/alkalis and aging; FPM resists strong acids and high temperatures

Typical Applications of UPVC Union for Industry

  • is installed at inlets/outlets of valves, pumps, and instruments in chemical piping.
  • serves industrial pipe sections requiring periodic disassembly for cleaning or inspection.
  • is placed in long straight runs for sectional disassembly.

Application Scenarios of UPVC Union for Industry
