Buttfusion Steel Transition Fittings for PE and Steel Pipeline Systems
Buttfusion Steel Transition Fittings are used to connect HDPE pipelines to steel pipe systems where a butt fusion joint is specified on the polyethylene side. The fitting combines a PE spigot end with a steel connection, creating a transition point between polyethylene and steel components within the same pipeline network.
These fittings are widely used in natural gas distribution, municipal water supply, industrial utility systems, and infrastructure projects where HDPE pipelines connect to steel valves, steel pipe sections, pressure control equipment, or existing steel networks.
Product Features
Butt Fusion Connection for HDPE Pipelines
The PE end is designed for butt fusion welding and can be connected directly to PE80 or PE100 pipes using standard butt fusion equipment. The welded joint becomes part of the pipeline, providing a continuous flow path.
01
Transition Between Different Pipe Materials
Buttfusion Steel Transition Fittings provide a connection point between HDPE and steel systems without requiring field fabrication of transition assemblies.
02
Suitable for High-Pressure Pipeline Applications
The fitting is commonly specified in gas and water transmission systems where secure pipe connections and long service life are required.
03
Compatible with Buried Installations
The polyethylene section offers the same corrosion resistance as HDPE pipe, making it suitable for underground utility networks and buried pipeline projects.
04
Factory-Assembled Construction
The PE and steel sections are permanently joined during manufacturing, helping ensure dimensional consistency and reducing installation work on site.
05

Typical Applications
Natural Gas Distribution Networks: Used where PE gas pipelines connect to steel service lines, isolation valves, pressure regulating stations, and metering facilities.
Municipal Water Supply Systems: Suitable for connecting HDPE transmission pipelines to steel valves, pumps, reservoirs, and treatment plant equipment.
Industrial Utility Pipelines: Installed in industrial water systems, cooling water networks, and process utility pipelines where both HDPE and steel materials are used.
Pipeline Rehabilitation Projects: Frequently selected when sections of aging steel pipeline are replaced with HDPE pipe while retaining existing steel infrastructure.
Infrastructure Construction: Applied in utility projects requiring reliable connections between polyethylene and steel pipe systems.
