Reducer Fittings for Diameter Changes

Tunnels, dams and large-scale infrastructure pipelines change diameter as demand changes. Our concentric and eccentric reducers provide smooth transitions between different pipe sizes, maintaining optimal flow velocity.

Precision fabricated and fused, the reducers maintain full pressure rating across the diameter change and resist corrosion across decades of buried service.

Key Features

  • Large diameter options for high-volume flow
  • Pressure-rated for demanding applications
  • Flexible joint systems for ground movement
  • Corrosion-resistant materials
  • Low maintenance over system lifetime

Applications

Tunnels

Piping for tunnel construction and operations.

Dams

Piping systems for dam and reservoir projects.

Infrastructure-Scale Piping with Project Logistics

Highways, rail and urban developments move massive water volumes through congested corridors. We stage-deliver pipe, fittings and fusion support on your construction sequence.

Mine sites destroy unsuitable pipe in months. Abrasive slurries, ground movement and rough handling demand the impact strength and wear resistance that only HDPE provides - which is why our systems are standard equipment on dewatering, tailings and process water duty worldwide.

We support project logistics end-to-end: bundled coil and stick deliveries to remote sites, fusion crews and equipment mobilisation, and staged supply programmes that match your construction sequence rather than fighting it.

Superior Abrasion Life

4x wear life of steel in slurry service, cutting replacement frequency

Impact Toughness

Survives rough handling, rock impact and ground settlement

Lightweight Sections

Up to 90% lighter than ductile iron - helicopter and manual deployable

Fast Fusion Crews

Butt welding on site at 10x the speed of flanged steel assembly

Float & Submerge

Wall buoyancy options enable pontoon and submerged pipeline layouts

Rapid Deployment

Long coils and electrofusion repair kits keep dewatering online 24/7
