Quality Assurance Program

Steel Fabrications

The following procedures are employed to ensure conformance with quality and design specifications for steel weldment fabrications:

1. Steel fabrication facilities are pre-inspected and are categorized according to their capability and experience in the following areas:

*      Truck access for raw material and fabricated weldments.
*      Steel stock storage capability.
*      Lifting, bending, shearing capabilities.
*      Welding area size and access capability.
*      Welding equipment type and capability.
*      Welders AWS or ASME current certification and qualification levels.
*      General shop appearance, neat, orderly, safe.
*      Safety procedures documentation.
*      Personnel protective equipment use, familiarity, and condition.

2. Design and fabrication drawings are produced at Hydro-Flo Technologies.  Final drawings are approved by an Engineering Department designee for completeness, conformance with project specification, conformance with in-house specifications, and safety.
    

3. Fabrication of steel weldments is inspected by a Hydro-Flo Technologies Production Department designee for conformance with Hydro-Flo Technologies fabrication drawings prior to acceptance by Hydro-Flo Technologies.  The following are minimum conformance inspection procedures:

*      Nozzle type, placement, size.
*      Dimensional conformance, entire weldment.
*      Warp or other disfiguration.
*      Weld porosity and appearance.
*      Weld leak testing with dye penatrant.
*      Special appurtenance detail conformance.
*      All edges checked for smoothness.  NO sharp edges allowed!

4. Steel coating facilities are pre-inspected and are categorized according to their capability and experience in the following areas:

*      Truck access for fabricated weldments.
*      Coating stock storage capability.
*      Surface preparation systems capabilities.
*      Coating area size and access capability.
*      Coating equipment type and capability.
*      Coating application personnel’s current certification and qualification levels (if any).
*      General shop appearance, neat, orderly, safe.
*      Safety procedures documentation.
*      Personnel protective equipment use, familiarity, and condition.

5. Coating of steel weldments is inspected by a Hydro-Flo Technologies Production Department designee for conformance with Hydro-Flo Technologies fabrication drawings and coatings specifications prior to acceptance by Hydro-Flo Technologies.  The following are minimum conformance inspection procedures:

*      Surface preparation conformity including steel exposure limits prior to coating application.
*      DFT and WFT conformity (as applicable).
*      Holiday investigation.
*      Weld coatings appearance.
*      All edges checked for smoothness and coating coverage.  NO sharp edges allowed!

6. Final shop inspection at Hydro-Flo Technologies during and after final assembly is performed by the Hydro-Flo Technologies Production Manager.  Final inspections include at minimum:

*      Conformity of the entire system to the fabrication and shop assembly drawings and documents.
*      Form/fit/and function of all major and minor components and appurtenance.
*      Electrical system checkout including logic controls for proper operation, load and configuration.
*      Proper preparation for shipment and storage. 
*      Protective enclosures and skids, temporary preservative coatings.
*      Partial disassembly and packaging of certain components for secure shipment.
*      Lifting, trucking, safety, and handling labels.
*      Shipping document preparation and notification of receiving party.

7. Field follow-up includes phone contact with project manager or other appropriate designee to obtain immediate feedback.  Long term quality feedback includes a quality satisfaction survey form sent to the project manager or other appropriate designee to solicit feedback.  Any problems listed on the quality survey form are immediately addressed by Hydro-Flo Technologies management.  Quality excursions (if any) are addressed with the appropriate department and steps are implemented to ensure elimination of problem areas.
