MicroStop - Pipeline Technology Ltd

MicroStop

MicroStop is a miniature FlowStop system offered for pipe sizes from 1" to 3" and working up to a maximum pressure rating of 500mb. The built-in bypass to the stopple head allows for gas flow to continue uninterrupted whilst maintenance and repair activities are completed.

Previously, leaks on multi-occupancy buildings led to an automatic shut-down of the riser pipe feeding the property. Most of which would lead to a complete replacement of the riser pipe.

This left customers without hot water, being unable to cook and leaving some without heating, which resulted in them feeling very dissatisfied with their energy provider.

As a result, networks found they were constantly offering compensation to their customers. The TOTEX and OPEX costs of these types of operations, especially where new systems have been installed, have been massive.

This allows for repair work to be carried out, without needing to cut off supply. The bypass hose is available in 1" for Mod 1, 2" for Mod 2 and 3" for Mod 3 allowing the diameter of the hose to match that of the main. This prevents any decrease in flow on a low-pressure gas pipe.

The revolutionary piece of equipment has already drawn huge attention from the likes of SGN and Cadent Gas, who have both verified the capabilities of the MicroStop, and have used the MicroStop on their own projects. The MicroStop equipment provides the supplier with the ability to identify the problem area, isolate and replace the offending section of pipe whilst keeping continuity of supply to its customers.

Pipetech led an exciting project and provided on-site training to the operational teams from Cadent Gas, which demonstrated the capabilities and significant benefits of the MicroStop equipment.

The project took place on a block of flats in London. Dozens of families were at risk of having their gas supply cut off due to corrosion on the steel supply pipe. Gas to this multi-occupancy building was provided by a steel supply pipe (above ground), which transitioned to PE pipe below ground level.

The MicroStop system showed how the pipe can be repaired without cutting off the gas supply to residents. The use of this system significantly reduces the complexity of this repair task and offers the following benefits:

  • No requirement to gain entry into every dwelling and the problems this creates.
  • Dedicated teams can work as soon as notified.
  • Avoids pressure testing a complete system, with only the replacement section being tested.
  • Carbon footprint reduced dramatically.
  • Improvement in customer service is immeasurable.
  • Financial savings prove there is no comparison.
  • Reduction in operational and logistical cost to the gas companies.
  • No interruption to the gas supply.
  • Prevention of potential fines (due to the lack of interruption).
  • Minimised disruption to the residents.
  • Reduction of time required on site to perform the operation.
  • Repair operations completed by one team.
  • Microstop can be used in a variety of use cases on all multi-occupancy buildings
  • Microstop boasts multiple benefits, not just to gas delivery networks, but to residents also and improves customer relationships
  • Microstop has many indirect benefits on the environment and reduces the carbon footprint of the operation
  • MicroStop allows for broken or damaged sections of gas pipes to be repaired whilst the feed remains live. This means no shut-down penalties or customer compensation.

    HOW MICROSTOP WORKS:
    ISOLATED LEAKING PIPE

    The MicroStop utilises an expanding stopper mechanism, to create a 100% leak proof block, isolating the broken section of pipe.
    BYPASS
    The bypass hose is available in differing lengths which can be joined to suit the application. The model 2 MicroStop bypass offers size for size bypass which prevents any decrease in flow rate on low pressure systems
