Materials & Standards
Standards-based communication for stainless sourcing.
Use clear technical language for sanitary valves, fittings, tubing and industrial stainless pipe RFQs. Standards help reduce confusion before quotation and support contractor/OEM communication.
Standards Library
Technical standards used in RFQ preparation.
These pages are not a substitute for certified engineering review, but they help structure sourcing communication with suppliers, contractors and plant buyers.
Sanitary Design3-AHygienic design language for food and dairy equipment.
Hygienic DesignEHEDGCleanability and hygienic design principles.
Sanitary TubingASTM A270Sanitary stainless tubing for hygienic process lines.
High-PurityASME BPEBioprocessing and high-purity equipment language.
Industrial PipeASTM A312Welded and seamless stainless pipe for industrial lines.
How standards support better RFQs
For sourcing, standards should be used to clarify expected material grade, product family, finish, connection, documentation and application environment before quotation.
- Clarify sanitary vs industrial product categories.
- Separate ASTM A270 tubing from ASTM A312 pipe.
- Identify high-purity and hygienic design expectations.
- Improve quote accuracy and reduce supplier back-and-forth.
RFQ checklist
Include these fields when requesting products with standards requirements.
- Product type, size and quantity
- Material grade: 304 / 316L / 304L / 316L
- Standard reference and application
- Finish, connection and documentation requirements
- Drawings, BOMs, photos or existing part references
Comparison Matrix
Common standards by product family.
| Standard | Common Product Area | Typical RFQ Use |
|---|---|---|
| 3-A | Sanitary valves, fittings, tubing and hygienic components | Hygienic design and cleanability expectations for food/dairy applications. |
| EHEDG | Hygienic process equipment | Cleanability and sanitary equipment design language. |
| ASTM A270 | Sanitary stainless tubing | Sanitary tube size, material and finish communication. |
| ASME BPE | High-purity tubing, fittings and process equipment | Biotech/pharmaceutical-oriented finish and geometry language. |
| ASTM A312 | Industrial stainless pipe | Welded/seamless industrial pipe, schedule and material grade communication. |
