Technical planning
Ask for a product-contact materials list tied to the supplied machine. A general “stainless steel” claim does not identify every valve, tube, fitting, gasket and seal that touches the product. Material suitability must be reviewed against the actual water and cleaning conditions.
Request a marked drawing or list distinguishing wetted parts from frame, guards and other non-contact components. Give the supplier the product and cleaning conditions available from your process team, with unknowns clearly identified.
Require grades and material descriptions for the relevant parts rather than one grade assigned to the whole machine. Ask the supplier to explain compatibility and any excluded conditions. Do not prescribe a universal grade or seal compound without a project review.
Review supplier declarations and certificates for scope, issuer, date and traceability to the relevant part or batch where required. A document for unrelated raw material or a different machine should remain an open evidence item.
Retain the final material register with as-built drawings and part numbers. Replacement seals and product-contact parts should be ordered by approved identity, with changes reviewed for compatibility.
No. Review the actual wetted components and the declarations required for the product, cleaning conditions and destination.
The project review should determine suitability component by component. A website cannot select a universal grade for unspecified water and cleaning chemistry.
Use one wetted-parts register, ask both bidders to state grades and seal materials, and compare traceability, compatibility evidence, substitutions and exclusions.
