HIGH-PURITY & HYGIENIC SYSTEMS

Pharmaceutical & Biotech

Process and clean-utility pipework supported by controlled fabrication, traceable welding and documentation for qualification activities.

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.

Purified water & WFI

Distribution loops, points of use, equipment connections and associated valve assemblies.

Welding & procedures
Orbital GTAW (TIG) for suitable repeatable tube joints; manual TIG where access or geometry requires, under the approved procedure.
Inspection & quality
Material and surface-finish records, weld identification, internal inspection where specified, pressure testing and cleaning records.
Applicable frameworks
ASME BPE for specified hygienic requirements; ASME B31.3 where adopted as the piping code; project water-quality and qualification requirements.

Clean steam & SIP

Sterilisation services, clean-steam distribution, condensate return and equipment interfaces.

Welding & procedures
Qualified TIG / orbital procedures selected for material, wall thickness and joint configuration, with controlled root shielding.
Inspection & quality
Drainability and slope verification where specified, weld examination, integrity testing and documented reinstatement.
Applicable frameworks
Project-adopted ASME BPE and pressure-piping code; approved thermal-service and sterilisation design basis.

Product transfer & CIP

Hygienic transfer lines, cleaning circuits, skids and bioprocess equipment connections.

Welding & procedures
Controlled TIG / orbital welding, with repeatable preparation, fit-up and purge controls.
Inspection & quality
Inspect internal weld profile and specified finish; verify cleaning interfaces, segregation and approved acceptance criteria.
Applicable frameworks
ASME BPE where specified; client GMP / validation framework and approved process requirements.

Plant utilities

Process gases, compressed air, cooling water and general mechanical services.

Welding & procedures
Manual or mechanised TIG selected to suit the service and approved welding procedure.
Inspection & quality
Material traceability, visual and specified NDT, pressure / leak testing and turnover packs.
Applicable frameworks
ASME B31.3 or AS 4041 where specified; service-specific cleanliness and client acceptance requirements.

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.
