Threaded PE Steel Transition Fittings for Connecting HDPE Pipes to Threaded Equipment

Threaded PE Steel Transition Fittings are designed for applications where HDPE pipelines need to connect to threaded steel components. The fitting combines a polyethylene end for fusion welding with a threaded steel connection, allowing HDPE pipe systems to be connected directly to valves, meters, pumps, regulators, and other pipeline equipment.

They are commonly used in gas distribution, water supply, irrigation, and industrial utility systems where threaded connections are part of the pipeline design.

Product Features

Transition Between HDPE Pipe and Threaded Steel Components

The fitting provides a connection point between polyethylene pipelines and threaded metal equipment without requiring additional transition assemblies.

Compatible with PE80 and PE100 Pipe Systems

The PE end can be joined to HDPE pipes using standard butt fusion or electrofusion methods commonly used in pipeline construction.

Multiple Thread Options Available

Threaded connections can be supplied with BSP, NPT, or other thread standards depending on local specifications and equipment requirements.

Suitable for Underground and Above-Ground Installations

The polyethylene section can be installed within buried HDPE pipe networks, while the threaded steel end allows connection to exposed equipment and pipeline accessories.

Factory-Manufactured Assembly

The PE and steel sections are permanently joined during production, providing a ready-to-install fitting for field applications.

Available Configurations

Depending on installation requirements, Threaded PE Steel Transition Fittings can be supplied as:

PE to Male Thread Adaptors
PE to Female Thread Adaptors
Male Thread Transition Fittings
Female Thread Transition Fittings
PE Steel Threaded Connectors
Customized Threaded Transition Assemblies

Special dimensions and thread specifications can be manufactured according to project drawings.

Typical Applications

Gas Distribution Systems: Used where PE gas service lines connect to threaded regulators, valves, meters, and customer service connections.

Water Supply Networks: Installed in municipal and rural water systems where HDPE pipelines interface with threaded mechanical equipment.

Irrigation Projects: Suitable for connecting HDPE pipework to filtration systems, control valves, pumps, and irrigation equipment.

Industrial Utility Pipelines: Applied in industrial water distribution systems and utility networks that combine HDPE piping with threaded steel components.

Pipeline Repair and Extension Work: Often selected when new HDPE sections are added to existing threaded steel pipe installations.
