Cross-Country & In-Plant Pipelines

Engineering, fabrication and installation of ammonia pipelines (liquid & vapour) from in-plant routing to long-distance cross-country pipelines with full stress, insulation and cathodic protection design.

Pipeline projects begin with route surveys, geotechnical investigations and corridor planning to avoid utilities, environmentally sensitive zones and cultural/landowner constraints. Stress analysis considers thermal expansion, anchor spacing and pigging requirements; where buried, we design for soil corrosivity, bedding and cathodic protection. For long cold lines or refrigerated pipelines, insulation and vapor barrier design are included alongside expansion joint strategies and inspection access points.

Testing and commissioning protocols include pigging plans, nitrogen purging, vacuum drying (where required), and hydrostatic/pneumatic tests with witnessed records. For cross-country installations we prepare right-of-way documentation, third-party coordination plans and emergency isolation stations at defined intervals.
