Wellfab Services Ltd. Hot Tapping & Line Stopping | Pipe Fabrication & Welding

09/03/2026

WellFab completed a double 4” line stop with a temporary bypass to provide the isolation required for the installation of new three-way valves.

The bypass allowed system operation to be maintained while the two line stops isolated the section of piping being modified.

This allowed the contractor to complete the valve installation without draining the system and without a full shutdown of the data centre’s critical mechanical infrastructure.

For facilities where shutdown windows are limited or simply not practical, line stopping can provide an engineered method of isolating existing piping while maintaining service to the rest of the system.

WellFab successfully executed two 24-inch hot taps on a live, operating piping system, creating new large-diameter connection points while maintaining continuous system operation.

From connection preparation and valve installation to equipment alignment, controlled cutting, coupon retrieval, and final verification, every stage was planned and executed under live operating conditions.

Throughout the cutting operation, system conditions and equipment performance were continuously monitored to maintain control and ensure precise ex*****on.

The result: two fully established 24-inch connection points without draining the system, interrupting service, or taking critical infrastructure offline.

This is where hot tapping delivers its real value: enabling system expansion, modification, and new connections while existing infrastructure remains in service.

When shutdown is not an option, ex*****on matters.
