Technical procurement data
Standards, supply and inspection
Stainless Steel Pipe Fittings is supplied as a pipe fitting within the stainless steel products family. A reliable enquiry identifies the exact designation, governing standard, dimensions, condition, inspection scope and documentation before quotation.
| Material / grade | Stainless Steel Pipe Fittings; confirm the exact grade, temper or heat-treatment designation on the purchase order. |
|---|---|
| Product form | Pipe fitting |
| Standards and order reference | State the governing ASTM, ASME, EN, DIN, JIS, GB, AWS or customer specification on the purchase order; no standard is assumed from the product name alone. |
| Dimensions and tolerances | State the required section or diameter, wall or thickness, length, tolerance, straightness or flatness, edge/end condition and machining allowance. |
| Surface and supply condition | Hot-finished, cold-worked, solution-annealed, pickled, ground or polished condition is stated on the order as applicable to the product form. |
| Inspection options | The inspection plan may include material identification, chemistry and mechanical-property review, dimensional and visual inspection, plus hydrostatic, eddy-current or ultrasonic testing when required by the governing specification. |
| MTC and traceability | Specify EN 10204 3.1 MTC or the required certificate type, heat/lot traceability, inspection reports, marking, packing list and any third-party release before order confirmation. |
| Typical applications | Application suitability is confirmed from the specified grade, product form, operating temperature, process media, fabrication route and governing standard. |
| RFQ checklist | Send the pipe fitting grade and standard, required dimensions and tolerance, quantity, surface/condition, inspection and certificate requirements, packing preference and delivery destination. |
Final compliance is defined by the purchase order, approved drawing and issued mill documentation. Availability is confirmed for each grade, size and production route.
Buttweld and Pressure Piping Components
Stainless fittings supplied by grade, class, dimensions and inspection requirement

| Inspection | Visual, dimensional, PMI and NDE scope as specified |
| Documentation | Heat traceability and agreed certificate package |
Standards and Selection Notes
ASTM A403/A403M
Covers wrought stainless steel fittings for pressure-piping applications and uses grade/class designations that identify material and construction requirements.
ASME B16.9 dimensions
Factory-made wrought buttwelding fittings are commonly ordered to ASME B16.9 dimensional requirements. State size, schedule, fitting type and dimensional standard.
Low-pressure fittings are a different scope
As-welded fittings for low-pressure, low-to-moderate-temperature corrosive service may fall under ASTM A774/A774M. Do not substitute one fitting specification for another without design approval.
Typical Applications
- Chemical and process piping
- Food, beverage and hygienic utility systems
- Water-treatment and desalination systems
- Energy and general industrial piping
- Marine and coastal piping assemblies

Frequently Asked Questions
What information is needed for a fitting quotation?
Provide grade, specification, class, fitting type, nominal size, schedule or wall, dimensional standard, quantity, NDE, certificate level and delivery destination.
What is the difference between seamless and welded fitting classes?
The class identifies the manufacturing route and examination requirements within the governing specification. State the required class rather than accepting an unspecified construction.
Can fittings be supplied with PMI?
PMI and other inspection requirements can be included when specified before quotation. Define the method, sampling rate, acceptance basis and required report.
