Hot Tapping involves a number of specialised procedures, used in conjunction to create a safe way to manipulate pipelines without interrupting the flow of hazardous substances. This can involve;

• A hot tap saddle or weld nozzle

• Valve installation

• Pressure testing

• Drill pilot

• Cutter and coupon

Ultimately, this technique is a way of providing a connection method for the pipe in question. Drilling and cutting a predetermined pipe can save a lot of hassle and protect the infrastructure, especially in areas where there may be frequent usage and possible corrosion.

Not only do we at RDS Pipeline Isolation understand the practicalities of the sensitive nature of this technique, but we also can provide understanding and advice when NOT to use hot tapping. Some conditions that are inferior for hot tapping include;

• Pipes with combustible and flammable substances

• Pipes with pure oxygen and chlorine

• Sulphur compounds

• Certain acids, peroxides, or other chemicals that are especially sensitive and reactive to the heat in welding machines

We have a high code of conduct, and we aim to provide you with the best advice and practical administration of Hot Tapping that is possible for the circumstances. You can trust RDS Pipelines to never steer you wrong.
