Special works Hot-Tapping joints
We make connections of new consumers to the existing gas pipeline in exploitation, without stopping the gas supply to other consumers.
- We make hot tapping connections of under pressure pipeline up to 16 bar, the size up to DN100
- Upon request, we can make it at larger dimensions and pressure
- Used in gas and oil pipelines, district heating systems, plumbing and all other pipelines
The advantages of Hot tapping:
- There is no suspension of the energy
- There is no cost to the discharge piping
- No need for inertisation of pipeline
- There is no need to announce delays in delivery of gas
- The time required for the works is 3 hours from the time of access to the site
- Warm connections can be made on steel, polyethylene, GRE, concrete and other pipes
In the hot terminal the blocking valve is instlalled which also serves as a sectional valve.
Welds on the hot terminal are recorded radiographically, and the warm connection is tested at 25 bar.
Without risk, with minimal cost and in a short time we will provide a connection for a new consumer to the existing network.
