Pressure vessel and piping inspection

QUALITAS TR inspects pressure vessels, heat exchangers, storage tanks, piping spools and skids during fabrication on behalf of buyers and EPC contractors. Scope follows the ITP and typically includes material and certificate verification, marking transfer, welding procedure and welder coverage, fit-up and welding inspection, NDT review, post weld heat treatment records, dimensional checks, nozzle orientation, hydrostatic or pneumatic test witnessing and final documentation.

Where the equipment is placed on the EU market under the Pressure Equipment Directive or built to the ASME code, statutory conformity assessment is performed by the notified body or authorized inspector. QUALITAS TR works alongside them as the buyer's inspector.

Pressure equipment carries stored energy; failures are serious. Codes define minimum requirements, but buyers often specify additional requirements for materials, NDT or testing that the statutory inspector does not check.

Buyer inspection ensures that both code and project requirements are met and documented.

In Europe pressure equipment is designed and built under the Pressure Equipment Directive, often using EN 13445 for unfired vessels and EN 13480 for industrial piping. ASME Section VIII and B31.3 are common for international projects. Welding qualification follows ISO 15614 and ISO 9606 or ASME Section IX.

Our metallurgical background helps with the decisions that matter most in pressure equipment: material substitution requests, impact testing, heat treatment and hardness limits for sour service.
