Gas Service Renewal
Live Service Insertion
Gas Service Insertion
Our live gas service insertion technique, using our patented FOAMPACK™ product, allows companies to renew gas service pipes without interrupting the mains supply and without excavating in the road or footpath. It is designed for use on steel services up to 2” diameter operating at low pressure.
The FOAMPACK™ system is well proven having been in use as an annular sealant for over 20 years. Our no-gas cut off technique, Live Service Isolation, may be carried out prior to insertion – see below:
Benefits
- Substantial cost-saving as a repair or cut-off method
- Avoids the need to excavate in the road or footpath
- Eliminates risk of personnel working in the highway
- Annular space sealed with expanding resin foam
- Quick and easy to use

Live Service Transfer
Live Service Transfer
This technique allows a gas service to be partly re-laid and/or transferred to a new main without disrupting the customer’s gas supply.
A solution to the replacement of services to multi-occupancy properties, it also meets the need for renewing uninterruptible supplies such as shops, restaurants and hotels.
Live Riser Transfer is an enhancement of the system. Carried out by our contract service team, it enables the operator to replace an existing property entry point or modify internal pipework under live conditions.

Live Gas Service Isolation
Rapid Service Isolator
Live Gas Service Isolation was developed at the request of the gas industry for a safe alternative to the traditional method of cutting service pipes in live gas conditions.
This technique developed by Steve Vick International allows an operative to isolate a metallic low pressure service under ‘no gas’ conditions to enable the service to be safely cut and subsequently dead inserted with a new PE pipe.
Currently, the technique is available for low pressure services (up to 75 mbar) with diameters from ¾” to 1¼”, but it is envisaged that larger diameters will subsequently be added.

The service is accessed via a small excavation and, using the Steve Vick International Isolator Clamp, the pipe is drilled in no-gas conditions and a temporary stopper is inserted. The operation takes only a few minutes and the service can then be live inserted or capped in the case of abandonment.

Gas Service Renewals – Dead - FOAMPACK™
FOAMPACK™
We offer several options for filling the annulus when services are inserted dead.
Our FOAMPACK™ kits are a convenient annular sealant for injecting from the service head adaptor to fill the prescribed length of the old service.
FULLSEAL™

Taper Tool
Service Taper Tool
When dead inserting gas services from outside the premises, it is customary to chamfer the leading edge of the PE pipe to aid speedy insertion.
The Service Taper Tool provides a safe and simple alternative to using a knife or hacksaw to slice a section off the PE to allow it to be pushed easily around even a tight bend into the building.
Now available in 20mm and 25mm sizes.
Live Service Insertion Removal Tool
Live Service Insertion Removal Tool
Cutting through a live inserted metallic service to expose the PE has traditionally proved difficult.
This tool easily removes a section of the inserted metallic pipe, giving a reliable accurate cut and avoiding damaging the PE.
