Plate fluid dossier
Prepare fluid composition records for the plate fluid dossier review. Identify the substance, the circuit or component it concerns, and the relevant operating case. Include the composition or treatment information held by the project team, and ask the supplier which further fluid details are needed for the proposed item review. Ask which substances should be identified before requesting a plate material review?
Request or submit water analysis, according to the proposed purchase scope. Identify the substance, the circuit or component it concerns, and the relevant operating case. Include the composition or treatment information held by the project team, and ask the supplier which further fluid details are needed for the proposed item review.
Plate operating schedule
Prepare project condition schedule for the plate operating schedule review. Request the precise wording and conditions associated with the specification statement. Ask which equipment version the statement describes, and refer the wording to the buyer responsible for the measurement requirement before using it to compare a competing instrument proposal. Ask which operating cases should accompany the material enquiry?
Request or submit duty descriptions, according to the proposed purchase scope. Identify the relevant project operating cases separately in the requirement schedule. Include the circuit or equipment references for each case, and ask the supplier to state which proposed configuration its response addresses before comparing that response with another proposal for the same duty.
Cleaning material questions
Prepare cleaning fluid descriptions for the cleaning material questions review. Identify the substance, the circuit or component it concerns, and the relevant operating case. Include the composition or treatment information held by the project team, and ask the supplier which further fluid details are needed for the proposed item review. Ask what information should be submitted about the intended cleaning regime?
Request or submit cleaning requirements, according to the proposed purchase scope. Describe the exchanger condition and identify the areas or circuits concerned. Include the cleaning substances and maintenance records available to the buyer, and request a written response addressing the intended inspection or cleaning scope before discussing the corresponding work arrangements.
Plate document requests
Prepare material descriptions for the plate document requests review. Name the component and the intended fluid or process environment in the document request. Ask for the material description associated with the proposed item, and request a written response to the buyer specific material question before accepting a proposed substitution or alternative component. Ask which material documents should be requested for the proposed plate?
Request or submit traceability requests, according to the proposed purchase scope. Name the component and the intended fluid or process environment in the document request. Ask for the material description associated with the proposed item, and request a written response to the buyer specific material question before accepting a proposed substitution or alternative component.
Replacement plate identification
Prepare existing plate photographs for the replacement plate identification review. Identify the exchanger and the position of the plate concerned. Request drawings or annotated photographs showing the relevant plate features, and ask how the proposed replacement should be compared with the existing component before the buyer accepts its identification. Ask what information should accompany a replacement plate material question?
Request or submit equipment identification, according to the proposed purchase scope. List the equipment references and identify the particular instrument or assembly concerned. Attach the available nameplate photographs or specification documents, and ask the supplier to address those references explicitly when identifying the proposed item and its corresponding technical documents.
Material decision record
Prepare written suitability responses for the material decision record review. Name the component and the intended fluid or process environment in the document request. Ask for the material description associated with the proposed item, and request a written response to the buyer specific material question before accepting a proposed substitution or alternative component. Ask which unresolved material questions should be referred to the project engineer?
Request or submit proposal revisions, according to the proposed purchase scope. Identify the equipment reference and document version associated with the request. Ask for a corresponding document list for the proposed configuration, and check which requested documents are included or still need clarification before the buyer compares the description with the purchase scope.
Heat exchanger plate material selection: documents to request
| Ask about | Request with your inquiry |
|---|---|
| Which substances should be identified before requesting a plate material review? | Fluid composition records and water analysis |
| Which operating cases should accompany the material enquiry? | Project condition schedule and duty descriptions |
| What information should be submitted about the intended cleaning regime? | Cleaning fluid descriptions and cleaning requirements |
| Which material documents should be requested for the proposed plate? | Material descriptions and traceability requests |
Heat exchanger plate material selection: review the proposed arrangement
Send the plate material question with the stream description your process team can release, and label which information belongs to each side of the exchanger. Ask the supplier to identify the material proposed for that duty in its reply. Request the supporting material document for that proposal and compare its designation with the quotation. Record questions about alternative materials separately so an alternative name does not silently replace the material your team originally asked to review.
