Description
Northern Gas Networks require multiple suppliers on a framework agreement to provide products that will be used throughout the NGN network. The purpose of this framework is to ensure continuity of supply of the sealant and associated equipment to the business at agreed rates, lead times and to ensure products conform to the correct specification and standards. Items under the framework agreement must meet the necessary Gas Industry Standards in line with all new guidance and standards published.
Lot Division
| 1 | Annular sealants This sealant material is for internal application of sealant materials (which may be applied externally, being pumped into the annulus from an external source) used to prevent the passage of gas along the annulus formed between an inserted plastic pipe and an existing metallic pipe. |
| 2 | Leakage Sealants Materials used to make a full permanent repair on either metallic or PE pipe by means of either internal or external application. |
| 3 | Bar Hole Sealing A bar hole is a hole made in the soil or pavement with a hand-operated bar for the specific purpose of testing the subsurface atmosphere with a combustible gas indicator. The Materials used to plug a hole following bar hole work to provide a full permanent seal of the surface. |
| 4 | Flow Stopping The objective is to temporarily stop the flow in a specific area of the network without disrupting the remainder of the local network. |
| 5 | Live Insertion Utilising a gland box, the old main is kept live throughout the insertion process and the new PE is gassed up to maintain gas supplies to individual customers. After the new main is inserted, the main is still kept live to supply customers via the annular space between the two mains until it is convenient to transfer the services to the new main |
Renewal Options
3 year initial term with the option to extend a further 5 x 1 years thereafter
