From issued package to field installation
A process piping scope may involve material receipt, field handling, supports, equipment connections, tie-ins and testing. CNC performs the installation activities assigned to its work package and coordinates the handoffs that sit around them.
The pre-mobilization review should confirm:
- current piping and instrumentation diagrams, isometrics and line lists;
- material classes, specifications and traceability requirements;
- weld, examination and inspection criteria;
- tie-in boundaries, isolation and work windows;
- supports, access and lifting requirements; and
- test packages and turnover documentation.
Pipe fabrication, specialist inspection, heat treatment, painting and insulation are subcontractor-coordinated services in CNC’s documented delivery model. They are not represented as self-performed process piping capabilities. See pipe fabrication and installation for the division of responsibilities.
Tie-ins, supports and testing
Tie-in work requires a clear owner-approved plan for shutdown, isolation, verification and return to service. CNC can schedule the field work within a larger plant shutdown when multiple systems or trades share the outage window.
Related pipe supports and tubing and hydrostatic testing can be reviewed as separate, defined work packages. Connections to process equipment may also require coordination with boilermaking or millwright services.

Documented industrial experience
CNC’s existing portfolio records refinery piping work at Valero, FRP piping supply and installation at Domtar, piping installation at Suncor and a gas-line scope associated with the Jacques Cartier Bridge. The examples indicate experience across varied industrial environments and materials; they do not imply that every material, code or activity is available on every project. Client names, photos, values and detailed results require publication approval.
