QUALITY & COMPLIANCE
Quality and International Standards
Project-specific inspection, documentation and compliance requirements are confirmed against each contract.
QUALITY FIRST
Codes, documents and traceability.
Pressure-equipment requirements can differ by destination market, service and project category. We align the quotation basis with the specifications received.
Design basis
Applicable standards and design responsibilities are identified during the technical review.
Inspection
Testing, material verification and third-party witnessing are agreed where required.
Documentation
Manufacturing records and dossier requirements are coordinated before dispatch.
Certificate copies, validity, stamp applicability and scope should be verified with Tongyang for each order before reliance on any specific compliance claim.
