Gas Joint Repair

Flexspray Sealant is a two-part anaerobic system formulated to seal leaking mechanical and run lead joints on cast and spun iron and steel and ductile gas mains, conforming to the GIS/LC12 specification. ALH Systems has developed a 1ltr pressure pot to inject Flexspray under pressure to reinvigorate and seal joints directly.

Leaking joints can now be treated without leaving the surface and with minimal excavation. This can have a big impact where a series of joints needs to be treated at frequent intervals along a main road. Long-reach tooling allows the back of a socket to be drilled and tapped to accept a standard brass injection nipple.

Utilising a 1-litre pressure pot removes the need for an operative to use hand-operated applicator guns and is, therefore, safer, more ergonomic, and more efficient. The 1-Litre Pressure Pot enables Flexspray to be applied to the joint under pressure to ensure full penetration of the entire joint.

The portable kit is ideal for use on joints up to 12” and is easily carried in vehicles because it is small and weighs only 5 kg.

Maintenance of the kit is low and ALH Systems offer a full range of servicing and maintenance options.

Working in conjunction with ALH Systems Long Handled tooling, the 1 litre pressure pot is ideal for any emergency team. Lightweight and portable nature

Equipment

1. Back-of-socket long-handled tooling. This system drills, taps, and fits a brass injection nipple from above ground.

2. 1Ltr pressure pot, ideal for tier 1 joints. It is portable, easy to use, and requires very low maintenance.

This short film features Mike Nilsen, who takes us through how to use the 1-litre pot Flexspray product, which consists of the anaerobic consumable solution and the lightweight 1-litre pot equipment used to inject the repair solution into the joint safely.
