Stainless steel systems for operating plants, equipment installations and brownfield upgrades, with materials, welding and inspection selected for the process duty.
SYSTEMS & DELIVERY REQUIREMENTS
Built for the service.
Typical scope and project considerations. Final materials, procedures, inspection extent and acceptance criteria are agreed against the approved design and contract.
Process water & water treatment
Transfer pipework, filtration interfaces, treatment equipment and utility skids.
Welding & procedures
Qualified TIG / mechanised procedures selected for the specified stainless grade and joint.
Inspection & quality
Material verification, dimensional inspection, specified weld examination, testing and flushing.
Applicable frameworks
ASME B31.3 or AS 4041 where adopted; process-water quality and equipment specifications.
Steam & condensate
Utility distribution, condensate return, equipment connections and modifications.
Welding & procedures
Qualified procedures suitable for the specified grade, thickness and thermal duty.
Inspection & quality
Support and expansion interfaces, specified NDT, pressure testing and reinstatement checks.
Applicable frameworks
Project-selected pressure-piping code and thermal-service design requirements.
Chemicals & dosing
Corrosion-resistant transfer lines, dosing assemblies and skid connections.
Welding & procedures
Procedure selection accounts for material grade, filler and service; duplex requires its own qualified controls where specified.
Inspection & quality
Material compatibility review, traceability, weld inspection, leak testing and chemical-service documentation.
Applicable frameworks
ASME B31.3 or AS 4041 where specified; approved corrosion / materials selection and chemical-service design basis.
Compressed air & process gases
Utility distribution, manifolds and equipment hook-ups within the agreed service scope.
Welding & procedures
TIG / orbital methods selected for joint size, access and specified cleanliness.
Inspection & quality
Service-specific cleaning, leak testing, identification and turnover documentation.
Stainless steel selection is based on chemistry, temperature and operating conditions. Specialist review supports corrosion and materials decisions where required.
Plan brownfield execution
Field verification, shutdown sequencing, isolations and reinstatement planning connect workshop fabrication with the operating facility.
Qualify the welding approach
Use the applicable welding procedure specification, qualification records and personnel approvals. Inspection extent and acceptance criteria are established before fabrication.
Confirm the designQualify procedures & personnelPrepare & weldInspect & testDocument & hand over
WPS (welding procedure specifications), supporting qualification records and welder / operator approvals are established under the project-adopted framework, such as ASME BPVC IX or AS 3992 where applicable.
Project-specific assurance.
Code selection and editions, hygienic requirements and specialist inspection are confirmed for each system. References describe potential project requirements and do not imply CPT organisational certification. Specialist engineering, inspection and validation interfaces are allocated within the agreed delivery scope.
