Surface Finish
ASME BPE Surface Finish Designations
All finishes are profilometer-verified and recorded batch-wise. Cr/Fe oxide ratio checked for EP surfaces.
| Designation | Process | Ra Target (ID) | Typical Application |
|---|---|---|---|
| SF1 | Mechanical polish (ID + OD) | ≤ 0.51 µm | General bioprocessing |
| SF2 | Mechanical + electropolish | ≤ 0.38 µm | Pharma utilities |
| SF4 | Electropolish (ID only) | ≤ 0.38 µm | WFI / Clean steam |
Quality Assurance
QA & Traceability
Every BioPure order is backed by systematic QA checks from raw material receipt to final despatch.
XRF PMI on Every Heat
Positive material identification for every heat number received — alloy composition confirmed before production.
Profilometer Ra / Rz
Surface roughness measured batch-wise and recorded against ASME BPE SF1/SF4 targets.
Weld Bore-Scope Inspection
Orbital weld inspection against ASME BPE Annexe D — visual and bore-scope, every joint.
Full Documentation Pack
MTR, PMI, surface data, weld records and EC number shipped with every order.
Every BioPure order ships with a 3.1 Material Test Report traceable to heat number — chemical composition, mechanical properties and surface finish data included.
