Intro Product Summary

Both versions—short neck and long neck—serve the same purpose but are selected based on installation space, pressure distribution, and mechanical requirements.

• Short Neck Adaptor:compact, ideal for tight spaces or installations with limited room.
• Long Neck Adaptor:extended barrel for better load distribution and increased support around the flange.

Together, they offer flexibility for a wide variety of engineering layouts.

Key Features

1. Two Structural Options for Different Site Needs
   Short neck for compact assemblies; long neck for applications where additional reinforcement is beneficial.
2. Strong Fusion Compatibility
   Both adaptor are designed for butt fusion welding, forming a joint with strength equivalent to the pipe itself.
3. Reliable Connection to Flange Equipment
   Offers a stable mechanical interface to pumps, valves, steel pipes, and control units.
4. Long-Term Durability
   PE100 construction ensures high resistance to impact, cracking, and long-term stress.
5. Corrosion-Free Performance
   An ideal replacement for metal adaptor in corrosive or aggressive environments.
6. Suitable for Pressurized Systems
   Consistent performance across water, gas, wastewater, and industrial fluid networks.

Installation Guide

• Prepare and Align
  Ensure both the HDPE pipe and the adaptor end are clean and properly aligned in the fusion machine.
• Face the Ends
  Use the facing tool to create a smooth, square contact surface.
• Heat the Interface
  Apply the heating plate following fusion guidelines for the pipe diameter and SDR.
• Join and Hold
  Fuse the melted ends together with consistent pressure.
• Cooling Period
  Allow natural cooling before handling or connecting to the flange assembly.
• Attach Backing Ring
  Position gasket and bolts, tightening them evenly in a crisscross pattern.

The HDPE Butt Fusion Flange Adaptor is commonly used in:

• Municipal water transportation and distribution networks
• Pump stations, treatment facilities, valve chambers
• Low- and medium-pressure natural gas infrastructure
• Desalination plant pipelines
