DN-15f - Branch Connections PE

by Alan Milford, from the Community

Use this DN-15f checklist to guide safe, compliant PE branch connections on gas distribution mains. It outlines required tools and equipment, documentation checks, pipe and saddle preparation, electrofusion setup, cooling, and integrity checks. Follow steps for assembling valves and drilling equipment, pressure and let-by tests, safety precautions, drilling and removal, leak verification, corrosion protection, and sign-off.

DN-08d PE Service to PE Main Disconnection
Use this DN-08d checklist to guide the safe disconnection of a PE service from a PE main in gas distribution work. Steps include isolating the ECV, exposing the PE tapping, cutting and removing the section, capping service ends with electrofusion caps, and testing fittings with approved leak detection fluid. Guidance covers handling standpipes, sealing abandoned ends, washing off detection fluid, and confirming property isolation before sign-off. Designed for field assessments and training, with pass or retrain outcomes.

DN-17a: PE Single Squeeze-Off Procedure
This DN-17a procedure details how to carry out a safe single squeeze-off on PE gas mains for network isolation. It covers required documentation, tools and equipment, pipe identification and SDR checks, setting out squeeze points, establishing network pressure, assembling and pressure-testing a bypass and vent system, commissioning the bypass, and preparing and applying downstream and upstream squeeze-offs. Steps include cutting out and replacing the PE main using approved equipment and electrofusion, purging to achieve 90 percent gas-in-air readings, leak testing, and re-commissioning. Limits: LP up to and including 180mm mains and MP up to and including 63mm mains.

DN-08d: PE Service to PE Main Disconnection
This DN-08d checklist guides field teams through safely disconnecting a polyethylene (PE) service from a PE main. Steps include confirming customer isolation at the ECV, exposing the PE tapping, cutter setup and verification with approved leak detection fluid, and controlled cutting with a damp cloth barrier. It covers capping both ends using electrofusion caps, testing all caps and fittings, washing off leak detector residue, and removing or capping and labeling any standpipe. The process also seals abandoned pipe ends and confirms that all supplies remain isolated before final assessor sign-off.

DN-14a Electrofusion Mains Jointing up to 355mm
This DN-14a checklist guides safe, compliant PE mains jointing using electrofusion up to 355 mm. It details required tools, site setup and shelters, preparation of PE pipe, scraping and alignment, use of restraining and re-rounding clamps, generator and control unit settings, fusion and cooling times, and when to stand clear. It highlights gas safety with a 20 percent LEL threshold, cleanliness and contamination control, and separation distances. Quality checks include fusion indicators, movement, cleanliness, evidence of scraping, and printouts from the control unit, followed by assessor sign off.
