HDPE Butt Fusion Fittings

Product Overview

HDPE eccentric reducer manufactured from PE100 for pipe size transition with flat top alignment. The offset bore of this HDPE butt fusion eccentric reducer keeps the crown of the pipeline level, so air pockets cannot form at the reduction point and pumps stay primed. Available from OD 75 to 630 mm in PN10 through PN25, the HDPE butt fusion eccentric reducer is the standard choice for pump suction lines and trunk main transitions.

Key Features

Flat-Top Alignment: The HDPE butt fusion eccentric reducer holds the top of the line level, preventing air accumulation at pump inlets and high points.
PE100 High-Strength Material: Every HDPE butt fusion eccentric reducer is produced from virgin PE100 compound for a 50-year design life under continuous pressure.
Full-Strength Fusion Joint: Welded with standard butt fusion equipment, the HDPE butt fusion eccentric reducer forms a joint as strong as the pipe itself.
Broad Size Coverage: The HDPE butt fusion eccentric reducer covers OD 75 - 630 mm, serving distribution mains and trunk pipelines alike.
Rated PN10 - PN25: Each HDPE butt fusion eccentric reducer matches the pressure class of the adjoining PE100 pipe.
Corrosion-Free Service: Unlike metal reducers, the HDPE butt fusion eccentric reducer never rusts, scales or tuberculates, keeping full bore capacity for decades.

Production

Raw Material

Every HDPE butt fusion eccentric reducer starts from certified PE100 black compound with uniformly dispersed carbon black for UV resistance, meeting ISO 4427 and EN 12201 raw material requirements.

Molding Process

Small sizes of the HDPE butt fusion eccentric reducer are injection molded in one cycle, while large diameters are CNC machined from thick-wall PE100 segments, holding the offset geometry within 0.1 mm tolerance.

Quality Control

Each batch of HDPE butt fusion eccentric reducer fittings is gauged for end diameter, wall thickness and ovality, then sampled for hydrostatic strength per ISO 1167 before packing.

Applications

Pump station suction headers install the HDPE butt fusion eccentric reducer flat-side-up to eliminate cavitation.
Municipal water trunk mains use the HDPE butt fusion eccentric reducer where line size steps down along the route.
Industrial process water lines choose the HDPE butt fusion eccentric reducer for turbulence-free size transition.
Irrigation pumping stations rely on the HDPE butt fusion eccentric reducer to keep suction piping free of air locks.
