Key Features

Flanged Demountable Joint: The HDPE socket fusion stub end works with a loose backing flange, giving a bolted joint that can be opened for maintenance.
Precision Flare Face: The stub flange face of each HDPE socket fusion stub end is molded flat and true for uniform gasket compression.
PE100 Raw Material: Every socket fusion stub end is molded from virgin PE100 resin for high hydrostatic strength and impact resistance.
Leak-Free Socket Weld: The HDPE socket fusion stub end welds to the pipe in one homogeneous body, leaving the flange as the only serviceable joint.
Corrosion and Chemical Resistance: An HDPE stub end never rusts and isolates metal flanges from corrosive media and soil.
Full Size Coverage: The socket fusion stub end range runs 20 to 110 mm, matching PN10 and PN16 backing flanges to standard bolt circles.

Production

Raw Material

Every HDPE socket fusion stub end is molded from certified virgin PE100 resin with carbon black UV stabilizer, batch-tested for melt flow rate and density.

Molding Process

Each socket fusion stub end is injection molded with a face-forming core that produces the flare and socket in one cycle, holding face flatness within tight tolerance.

Quality Control

Batches of HDPE socket fusion stub ends are sampled for hydrostatic pressure tests at 20 and 80 degrees C, flare face flatness checks and socket depth gauging per ISO 4427 and EN 12201.

Applications

Municipal water networks use the HDPE socket fusion stub end to connect PE lines to gate valves, meters and hydrants.
Building water systems install this socket fusion stub end at pump suction and discharge headers.
Agricultural irrigation relies on the HDPE socket fusion stub end for demountable joints at filters and fertilizer injectors.
Industrial plants choose the socket fusion stub end where HDPE piping meets steel equipment nozzles.
