Quality Control

Provision for quality assurance must be made in every purchase regardless of the scope of the purchase award (i.e., supply, service, fabrication, erection). Quality assurance requirements for a particular purchase will be defined in the quality control plan for the projector will be defined by the project manager, using the categories described below:

Supplier Internal Quality Assurance

This is primarily used for equipment items considered commercial catalog, or off-the-shelf, normally mass-produced and with usually rigid Quality Control department standards provided by the manufacturer. At the very least, documentary evidence of quality control in the form of a "Certificate of Compliance" is required from the supplier prior to shipment. The project engineer normally receives the documentation, and upon request, informs the Quality Control department once the requirement has been satisfied.

This category may also be used in cases where distance or time may be a factor and/or inspection is not justified or required by Hongvadar.

Third-Party Quality Assurance

This category describes the services of an independent party to perform the inspection of the equipment, and would normally require the project engineer to specify the circumstances.

Circumstances where this may be appropriate include:

  • The customer has stipulated a specified quality assurance program.

  • The equipment is subject to a Code such as ASME, Building, Electrical, Safety, CSA, etc. In which case the project engineer must specify in the Request for Purchase which code must be met.

  • Equipment is fabricated in a foreign country, and for which travel costs are not justified for a Hongvadar inspector.

Quality Control

Hongvadar Quality Assurance

Equipment is inspected by a Hongvadar inspector at completion and, if necessary, during manufacture.

The procedure for inspections is defined in the Hongvadar procedure, and they are performed using suitable checklists and forms for general fabrications. The inspector maintains responsibility to ensure the fabricator’s conformance to Hongvadar specifications, and will immediately bring any deviation from those specifications to the attention of the project manager. Hongvadar’s general fabrication specifications are defined in the document, and this is used by fabricators and during inspection to assess conformity.

Inspection of equipment will generally include a review of the following aspects (as appropriate to the specific equipment and customer):

  • Dimensions and geometry, including tolerances.

  • The fit of parts.

  • Visual inspection of welds.

  • Check of material certificates

  • Review of supplier's welding procedures and welders qualifications.

  • Check of gaskets, fasteners, and other parts that are supplied loose.

  • Check surface finishes (paint finishes, grinding, polishing, etc. as appropriate).

  • Running check of motors and drives (where practical), including a check of noise and vibration.

  • Identification marks and nameplates.


Emphasis is placed on suitability for function and features that must interface to other equipment, for example, flange and foundation bolt hole pattern dimensions and geometric accuracy, and internal surface finishes.

A copy of the equipment drawing will be used at the inspection and is annotated with all checked dimensions and features and any variations or non-conformities, along with a record of the location, date, and inspector's name.

Photographs of the equipment are taken at the time of inspection, these show the complete equipment from various angles as well as the detail of any markings and nameplates. The photographs are filed in the project file for the equipment (with completed inspection forms and annotated inspection drawings).

Results of the inspection are recorded on the appropriate Hongvadar inspection form. Any actions required by the supplier (or Hongvadar) are recorded on a punch list. The completed form, with punch list, is reviewed with the supplier and a signed copy of the form (with annotated inspection drawing) is sent to the project manager.

Minor non-conformities are usually dealt with by the supplier, who will advise Hongvadar when they have been rectified, with photographs or other evidence and a copy of the completed punch list.

Significant non-conformities require a re-inspection by Hongvadar, after advice from the supplier that they have been rectified.
