HDPE Electro Fusion Fittings

Product Overview

The HDPE electro fusion 90° elbow turns a PE100 water main through a right angle using two electro fusion sockets. The heating coils are moulded into both socket walls and energized by a standard electro fusion control unit, so the corner becomes a monolithic PE100 junction with the same pressure rating as the pipe on either side. Available from DN 50 to DN 315 mm with PN10 to PN16 ratings, the HDPE electro fusion 90° elbow is the standard choice for buried potable water networks where a maintenance free change of direction is required.

Key Features

One Piece Moulded Corner: The 90° elbow is injection moulded as a single body, so there is no welded seam at the bend and the corner carries full pipe pressure.
True Right Angle: The bend angle is held to 90° during moulding, so the HDPE electro fusion elbow aligns the pipe run without springback or stress on the fused joints.
Electro Fusion Sockets: Both ends of the elbow use fused joints, so the connection to the pipe is permanent and leak tight at the corner.
No Metal Insert: The electro fusion 90° elbow keeps polyethylene in the water path, so there is no corrosion or galvanic risk at the corner.
Full PE100 Flexibility: After fusion the line stays flexible, so the buried HDPE main can absorb ground settlement at the corner without prying the fused sockets apart.
Maintenance Free: The fused joints are permanent, so the HDPE electro fusion 90° elbow needs no bolts or gaskets to inspect at the bend.

Production

Raw Material

The HDPE electro fusion 90° 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 90° elbow is injection moulded in one shot with both resistance coils pre positioned in the 90° socket walls; the bend radius and socket bores are held to ISO 4427-3 dimensions.

Quality Control

Every batch of HDPE electro fusion 90° 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

Street intersection corners in buried potable water mains use the HDPE electro fusion 90° elbow to turn the trunk line without a mechanical joint.
Obstacle avoidance routes the HDPE electro fusion 90° elbow around existing utilities, because the moulded corner keeps the PE100 line continuous.
Pump room riser entries install the electro fusion 90° elbow where the buried HDPE main turns upward, so the vertical riser meets the pump without a bolted joint.
Water treatment plant pipe galleries use the HDPE electro fusion 90° elbow at every gallery turn, where the fused sockets keep the corner leak tight under pressure cycling.
