Our Solution: A Precision Engineered, Non-Stop Pipeline Relocation Plan<\/strong><\/h2>\n

As a specialist in\u00a0high-pressure pipeline installation\u00a0and maintenance, we presented a custom-engineered solution centered on the proven technology of\u00a0Hot Tapping and Stoppling<\/a>. This method is the gold standard for live-line modifications, but its application on a 6.4MPa line demands unparalleled expertise.<\/p>\n

Our solution was a two-part master plan:<\/p>\n

1. Precision New Pipeline Installation:<\/strong>
We first installed the new 200-meter, DN500 diversion route using high-grade L415M SAWH (Submerged Arc Welded Helical) steel pipe, designed to match the existing system’s pressure rating. Every weld was executed and inspected to the highest\u00a0industrial pipeline construction\u00a0standards, ensuring long-term integrity.<\/p>\n

2. The Critical Tie-In: Hot Tapping & Double Block and Bleed:<\/strong>
This was the core of our\u00a0pipeline relocation services. We performed two\u00a0Double Block and Bleed\u00a0operations on the live mainline. Here\u2019s how this complex process works and why it\u2019s so effective:<\/p>\n
