For more than 50 years, WeldFit has helped operators around the world maintain, repair, modify and optimize pipeline systems. Our Canadian Service Centre in Acheson, Alberta, just west of Edmonton, provides local project support and technical expertise while remaining prepared to support customers across Canada. With equipment and personnel positioned to respond to both planned and emergency work, WeldFit delivers solutions for transmission, gathering, facility, LNG and petrochemical applications, with a focus on meeting applicable Canadian standards and regulatory requirements.

WeldFit provides complete hot tapping and line stopping services to support pipeline maintenance, repair, tie-ins, system modifications and emergency response projects across Canada. Across the Canadian market, double block and bleed (DBB) isolation has become the preferred line stop method for nearly all pipeline owner/operators, and WeldFit’s Dually® DBB technology is purpose-built to deliver it. Our capabilities span single and double line stops, Dually® double block & bleed line stops, temporary bypass systems and complete pipeline isolation solutions, backed by the equipment, expertise and field support to help operators safely maintain and modify their systems while minimizing disruption to operations.

WeldFit’s Dually® technology delivers double block and bleed isolation in a single, compact tool. By setting two independent seals with a monitored bleed between them, Dually provides the positive, verifiable isolation Canadian operations expect, as a simpler, more reliable and more cost-effective alternative to conventional two-stop DBB isolations on gas and liquid pipelines.
The Difference is the Design
Built upon the success of WeldFit’s single seal line stop technology, the Dually system features a single, compact, patent-pending pivot style plugging head with two seals. The compact head design improves maneuverability, allowing for easier and more reliable insertion into the pipeline and removal after the job is complete.

Quality fittings are essential to the construction, operation and long-term integrity of every pipeline system. WeldFit designs and manufactures hot tap and line stop fittings to the specifications and codes that govern Canadian pipelines, including CSA Z662, with options ranging from proven, off-the-shelf designs to custom-fabricated solutions engineered for a specific job. Our team weighs factors such as material compatibility, pressure and temperature ratings, flow requirements and installation conditions to confirm the right fitting for each Canadian application.

Recover Product. Reduce Emissions. Maintain Operations.
WeldFit’s mobile compression fleet keeps gas moving and keeps it in the pipeline. ReCAP® cross compression provides an alternative to flaring or venting during pipeline and facility operations by capturing and recompressing natural gas that would otherwise be released. By recovering valuable product and reducing methane emissions, ReCAP® can help operators support environmental objectives while maintaining operational efficiency. Mobile equipment is available for field deployment across Canada, supporting applications such as pipeline maintenance, blowdown reduction, facility operations and natural gas transmission systems.
