HDPE Electro Fusion Fittings

Product Overview

The HDPE electro fusion 45° elbow offsets a PE100 water main by 45 degrees through two electro fusion sockets. Gentler than a right angle fitting, the 45° bend keeps flow resistance low at the turn while still redirecting the pipe run around obstacles or aligning with a sloped main. The heating coils are moulded into both socket walls and energized by a standard electro fusion control unit, so the offset becomes a monolithic PE100 junction. Available from DN 50 to DN 315 mm with PN10 to PN16 ratings, the HDPE electro fusion 45° elbow is the standard choice for buried potable water networks where a low resistance change of direction is required.

Key Features

Low Flow Resistance: The 45° bend angle produces less head loss than a 90° fitting, so the HDPE electro fusion elbow keeps water velocity high and pumping cost down at the turn.
One Piece Moulded Body: The 45° elbow is injection moulded as a single body, so there is no welded seam at the bend and the offset carries full pipe pressure.
True 45° Geometry: The bend angle is held to 45° during moulding, so the HDPE electro fusion elbow aligns the offset pipe run without springback or stress on the fused joints.
No Metal Insert: The electro fusion 45° elbow keeps polyethylene in the water path, so there is no corrosion or galvanic risk at the offset.
Full PE100 Flexibility: After fusion the line stays flexible, so the buried HDPE main can absorb ground settlement at the offset without prying the fused sockets apart.
Maintenance Free: The fused joints are permanent, so the HDPE electro fusion 45° elbow needs no bolts or gaskets to inspect at the bend.

Production

Raw Material

The HDPE electro fusion 45° elbow is moulded from virgin PE100 compound rated MRS 10.0 per ISO 4427-3, with the resin lot recorded for full traceability from pellet to fitting.

Molding Process

Each electro fusion 45° elbow is injection moulded in one shot with both resistance coils pre positioned in the 45° socket walls; the bend radius and socket bores are held to ISO 4427-3 dimensions.

Quality Control

Every batch of HDPE electro fusion 45° elbows is gauged for socket diameter, ovality, coil resistance and bend angle, then sample welded and pressure tested to 1.5 times rated pressure before release; each fitting carries a batch code traceable to the raw resin lot.

Applications

Obstacle offset runs in buried potable water mains use the HDPE electro fusion 45° elbow to shift the pipe run around existing utilities without a sharp right angle that would raise head loss.
Sloped drainage connections install the electro fusion 45° elbow where a gravity line meets the horizontal main, because the gentle bend keeps flow smooth and avoids sediment settling.
Angled branch takeoffs use the HDPE electro fusion 45° elbow in place of a wye, because the fused socket gives a leak tight junction without a mechanical saddle.
Water treatment plant pipe galleries route the electro fusion 45° elbow at every gentle change of direction, where the low resistance bend keeps the system efficient under pressure cycling.
