Key Features

  • Concentric Reduction: Centerlines of both ends align, keeping the pipeline axis straight; suitable for concentric size changes in vertical or horizontal pipes.
  • Butt Fusion Joint: Pipe and fitting ends are heated by a heating plate and fused under pressure, creating a homogeneous joint.
  • Tapered Flow Path: Smooth conical transition minimizes local pressure loss caused by abrupt cross-sectional change.
  • High Rigidity: Injection molded with uniform wall thickness; no stress concentration at the reduction zone, excellent negative pressure resistance.

Production Technology

  • Manufactured via high-precision injection molding
  • Mold design ensures uniform wall thickness in the tapered section

Critical Process Parameters

  • Precise control of outer diameter, wall thickness, and end face perpendicularity at both ends
  • Streamlined design of the taper transition angle to minimize turbulence

Typical Applications

  • Diameter changes in siphonic main pipelines where pipe size increases as flow accumulates downstream
  • Connection between vertical stacks and horizontal pipes of different diameters at the base or top
  • Diameter changes on pump discharge piping

Application Scenarios

  • Straight pipe sections requiring diameter change in siphonic drainage systems
  • Large commercial building drainage networks
  • Industrial plant drainage systems
