HDPE Butt Fusion Fittings

Product Overview

HDPE reducer pipe manufactured from PE100 for size transition in water supply systems. Unlike a short molded reducer, this HDPE butt fusion reducer pipe integrates the taper into an extended straight section, giving the fusion machine enough pipe length to grip and weld both ends on large mains. The HDPE butt fusion reducer pipe covers OD 75 - 630 mm in PN10 - PN25 ratings per ISO 4427.

Key Features

Extended Straight Ends: The HDPE butt fusion reducer pipe provides full machine-grip length on both sizes for reliable field welding.
Long Smooth Taper: The gradual cone of the HDPE butt fusion reducer pipe lowers turbulence compared with short molded reducers.
PE100 High-Strength Material: Every HDPE butt fusion reducer pipe is made from virgin PE100 compound rated for a 50-year design life.
Full-Strength Fusion Joint: Both ends of the HDPE butt fusion reducer pipe weld with standard butt fusion machines for a monolithic transition.
Rated PN10 - PN25: The HDPE butt fusion reducer pipe matches the pressure class of adjoining pipe from OD 75 to 630 mm.
Corrosion-Free Service: The HDPE butt fusion reducer pipe never rusts or scales, keeping full bore capacity for decades.

Production

Raw Material

The HDPE butt fusion reducer pipe is produced from certified PE100 black compound with uniform carbon black dispersion, meeting ISO 4427 and EN 12201.

Molding Process

Large sizes of the HDPE butt fusion reducer pipe are CNC machined from thick-wall PE100 stock with extended parallel ends; smaller sizes are injection molded.

Quality Control

Each HDPE butt fusion reducer pipe is gauged for end diameter, taper smoothness and wall thickness, then sampled for hydrostatic strength per ISO 1167.

Applications

Large-diameter trunk mains use the HDPE butt fusion reducer pipe where fusion machines need extended grip length.
Pump discharge headers rely on the HDPE butt fusion reducer pipe for a smooth, low-loss step-up or step-down.
Water treatment plants install the HDPE butt fusion reducer pipe between process pipework of different sizes.
Industrial cooling water lines choose the HDPE butt fusion reducer pipe for gradual velocity changes.
