The skilled engineers at National Gas Services conduct a full range of mechanical maintenance work on gas pipelines, ensuring the network continues to operate efficiently and cost effectively.

Maintaining the national and local gas pipeline network requires specialist expertise. Our experienced team has developed robust repair and maintenance techniques that can eliminate the need for expensive valve replacements. To minimise costs and disruption, we can often repair valves without decommissioning the pipeline.

Our range of mechanical maintenance expertise includes:

• Flushing and sealing techniques using existing valve connections.
• Sealant-vent plug adaption carried out where bling plugs are fitted.
• Vent-sealant line replacement.
• Actuator and extension tube repair and replacement.
• Stem seal leak repairs.
• Re-validation and pressure testing on site.
