GREAT WALL Hot Tapping & Line Stop Solutions: Excellence Achieved in Africa!

We are thrilled to announce the successful completion of the 20 inch Diesel Pipeline Replacement Project for Line-5 in Africa, in collaboration with the project's client and subcontractor. This critical diesel/super gas multi-product pipeline, operating at 5.0 MPa, underwent a seamless 500-meter pipeline replacement—without shutdown—using our advanced Hot Tapping and Line Stop Equipment and Technology.

Throughout the operation, GREAT WALL brand Hydraulic Hot Tapping Machine and Hydraulic Line Stop Equipment performed with outstanding stability, reliability, and remarkably low noise levels. The coupon from the cut section was smoothly retrieved, showcasing the precision of our equipment.

A key highlight: our proprietary NBR sealing element maintained a zero-leakage seal at 5.0 MPa for 48 consecutive hours, setting a remarkable benchmark in high-pressure oil and gas pipeline Line Stop. This achievement reflects our commitment to safety, innovation, and operational excellence.

At GREAT WALL, we don't just provide equipment—we deliver solutions that keep energy flowing safely and reliably.
