Process equipment material selection is application-specific. Tanks, vessels, heat-transfer equipment and process piping may face different media, temperatures, pressures, cleaning regimes and fabrication constraints.
Start with design conditions
Describe the process medium, normal and upset temperature, pressure, cleaning or sterilization method, and relevant corrosion considerations. State the governing design code and have the responsible engineer approve the material and thickness.
Specify product form and documentation
Identify whether the project needs coil, plate, clad plate, pipe or fittings. Define grade, dimensions, tolerances, surface requirements, quantity, traceability and the material or inspection documents that must be supplied.
Review clad options carefully
Where clad material is being considered, specify the base layer and cladding grade, each layer thickness, total thickness and inspection method. Confirm the bonding route and acceptance criteria with the supplier and project engineer.
Before ordering, reconcile the quotation, technical submittals, inspection plan and delivery terms with the approved project specification.
