Electrofusion Steel Transition Fittings for PE-to-Steel Pipeline Connections

Electrofusion Steel Transition Fittings are used to connect polyethylene pipelines to steel pipe systems, valves, regulators, meters, and other steel equipment. The fitting combines an electrofusion PE socket with a steel connection, providing a transition point between HDPE and steel components within the same pipeline network.

They are commonly used in gas distribution systems, water supply infrastructure, industrial utility pipelines, and pipeline rehabilitation projects where PE and steel materials need to be integrated.

Product Features

Electrofusion Connection for HDPE Pipelines

The PE end contains an integrated electrofusion socket that allows direct connection to PE80 or PE100 pipes using standard electrofusion welding equipment.

Transition Between PE and Steel Systems

The fitting is designed for locations where polyethylene pipelines connect to steel valves, steel pipe sections, pressure regulators, or metering equipment.

Suitable for Restricted Installation Areas

Electrofusion fittings are often selected for projects where space is limited and conventional butt fusion equipment cannot be used.

Factory-Assembled Construction

The PE and steel sections are permanently joined during manufacturing, reducing installation work on site and providing a ready-to-use transition fitting.

Compatible with Underground Utility Networks

The polyethylene section provides corrosion resistance in buried applications, while the steel connection allows integration with existing steel infrastructure.

Available Configurations

Electrofusion Steel Transition Fittings can be supplied in several connection types, including:

Electrofusion Steel Transition Couplings
Electrofusion Steel Male Adaptors
Electrofusion Steel Female Adaptors
Electrofusion Flanged Transition Fittings
Electrofusion Steel Weld-End Transitions
Customized PE Steel Transition Assemblies

Custom dimensions and connection designs are available according to project specifications.

Typical Applications

Gas Distribution Networks: Used at service connections, regulator stations, valve installations, and meter assemblies where PE gas pipes connect to steel equipment.

Municipal Water Supply Systems: Suitable for connecting HDPE water pipelines to steel valves, pumps, and treatment plant equipment.

Industrial Pipeline Systems: Applied in industrial water treatment facilities, utility networks, and process pipelines requiring connections between PE and steel components.

Pipeline Rehabilitation Projects: Frequently installed when replacing aging steel pipelines with HDPE pipe while maintaining compatibility with existing infrastructure.

Underground Utility Installations: Commonly used in buried pipeline networks where corrosion resistance and long-term service performance are required.
