Process Pipework Fabrication & Installation
ASME B31.3-Compliant Pipework for Petrochemical Operations
Precision-engineered pipework for safe petrochemical operations.
PML Engineering deliver complete process pipework solutions — from initial site survey and design through to fabrication, testing, and on-site installation. All work is carried out in full compliance with ASME B31.3, ensuring your systems meet the highest standards of safety, reliability, and performance.
Our process starts with a detailed site assessment to capture exact project requirements. We then produce accurate isometric spool drawings, source and procure fully traceable materials, and manage every stage of fabrication in-house. Welding is performed by fully coded operators working to approved WPS/PQR/WPQ procedures, ensuring consistent quality and compliance.
We coordinate all required non-destructive testing (NDT), post-weld heat treatment (PWHT), and hydraulic pressure testing to verify system integrity. Protective coatings — including galvanising and specialist finishes — can be applied to suit your environmental and process demands.
