6. In-Process Inspection / Process control

Perform inspection at defined manufacturing stages.

Set up Inspection: Check liner dimensions and surface condition, verify liner thickness where specified, Inspect for cracks, deformation, scratches or other defects. Verify port/opening locations.

Filament Winding Inspection: Verify approved material batch/lot, checks resin preparation and mixing, monitor resin viscosity and gel time, Verify winding program/reference, Check fiber tension where required, Verify resin impregnation and fiber wet-out, Observe winding pattern and uniformity, Check for dry fibers, gaps, wrinkles and excessive resin, Record applicable process parameters.


Laminate Curing Inspection: Verify curing time and temperature, Record curing parameters where required, Ensure the product is not released for further processing before completion of the specified cure.

Product final release Inspection: Check trimming and machining, labels and identification, process records, inspect port/nozzle preparation, Check bonding/installation of ports and Inspect finished composite surfaces for defects such as Cracks, Delamination, Dry fibers, Air pockets/voids, Resin-rich or resin-starved areas. Fiber exposure and Surface damage.

Dimensional Inspection: Perform and record dimensional inspection according to approved drawings, report any dimension outside the approved tolerance including Overall vessel length, Internal/outer diameter as applicable, Wall/laminate thickness, Port/nozzle dimensions, Port location and orientation, End-opening dimensions, Critical fitting dimensions, End-closure dimensions and fitment.

7. Product Testing & Qualification Support

Responsibilities include preparation, inspection and recording of test samples for: Hydrostatic pressure testing, Leak testing, Burst-pressure testing, Pressure-cycle/fatigue testing, Long-duration pressure testing where applicable, RO membrane/component fitment verification.

During testing, the inspector shall Verify vessel identification and serial number, Confirm calibrated test equipment is being used, Record test pressure and holding time, inspect for leakage, deformation or abnormal conditions, Record observations and results, immediately report failures or abnormalities, Initiate , Maintain supporting records and traceability for Product Qualification Reports.

8. Final Product Inspection and release:


Perform final inspection before QC release, including Visual appearance and workmanship, Overall dimensions, Port configuration, Internal surface condition, External composite surface condition, End-Plate assembly, sealing surfaces, O-rings/seals where applicable, Product identification, Serial number, Nameplate/label, Pressure rating, Material/product traceability, packing condition were included in the inspection scope. Ensure all mandatory inspections, tests and records are completed before recommending the product for release.

9. Non-Conforming Product Identification and Control:

Identify and clearly mark non-conforming materials/products, Segregate rejected material where required, Inform Shift lead /Operations Manager immediately, Raise or assist in preparation of Non-Conformance Reports (NCR), Perform re-inspection after repair/rework, maintain inspection status identification: Accepted / Hold / Rejected.
