Examples of Innovation Works which Perfect Pressure Utilities can undertake

Bagging-Off System for Hydrants

In the Hydrant Mini Line Stop System the flow of water in the Main is not affected. A simple Golf Blade Saddle is fitted to the 'leg' between the Hydrant and the Main, through which a small hole is drilled under pressure. A Hydra™ stopping bag is inserted and inflated. Inflation is controlled by a pressurisation unit using the line pressure through the Sniffer Hydra™ Bag Service Spine in the entry hole. When inflated the defective Hydrant can be replaced and Hydra™ Bag removed.

Key Benefits:

  • Only the Hydrant is isolated
  • Main flow is not affected
  • No independent power source required
  • Supplies to customers unaffected
  • No discolouration
  • Suits restricted excavation
  • Compact & light weight

Through Bore hydrants

The new unique Through Bore Hydrant (TBH) provides unobstructed vertical access through a standard type 2 fire hydrant allowing for a wide range of activities to be undertaken whilst the main is still under full pressure. Typical applications include, pipe work inspection and replacement along with the renewal of fittings and monitoring the pressure and quality of water. Internal inspection can be made using a miniature camera, hydrophone or acoustic imaging equipment. In addition, the ability to pinpoint the exact location of a leak is a huge step forward in effective leakage management. Industry targets set by Ofwat include better management of the existing pipework infrastructure.

Line stop

Linestopping can be performed on many types of piping materials for water, such as- HPPE, UPVC, Cast Iron, Ductile Iron and asbestos

Why use linestopping?

  • Service to consumer’s process industries and sensitive services is maintained.
  • Contamination and / or loss of fluid does not occur.
  • Fire protection not affected.
  • No time wasted draining the systems.
  • Personnel are used efficiently on effecting repair.

Consider this against the cost of a shut down:-

  • Planning and co-ordination of shut down – meetings, schedules, paperwork.
  • Notification of consumers or process plant personnel.
  • Compensation to customers, loss of goodwill.
  • Lost production and therefore profit in process industry.
  • Direct labour cost – locate and activate valves.
  • Overtime rates for working at "low demand times" normally nights and weekends.
  • Drainage, purging and refilling of pipelines.
  • Disruption to road work systems by road closures.

By utilising under-pressure techniques work can be performed allowing alteration, relocation, extension, addition, repair, replacement, maintenance, or abandonment of pipework without shutdown or interruption of service to critical processes or consumers.

Quadrina

Quadrina Ferrule

Quadrina ferrules can be put into pipelines from 3" - 24" diameter, services can give sizes from 1/2" - 2". Complete with inner plugs or brass gate valves. Quadrina Ferrules can be inserted into cast and steel, and by using a gun metal saddle A/C, plastics and ductile pipes.

  • Service to consumer’s process industries and sensitive services is maintained.
  • Contamination and/or loss of fluid does not occur.
  • Toxic or harmful product is not released.
  • Fire protection – sprinkler systems, hydrants, etc are not affected.
  • No time wasted draining the systems.
  • Personnel are used efficiently on effecting repair.
  • Eliminates need for bulk transfer and storage of harmful fluids.

By utilising these techniques work can be performed allowing alteration, relocation, extension, addition, repair, replacement, maintenance, or abandonment of pipework without shutdown or interruption of service to critical processes or consumers.
