Testing & Inspection Procedure
All IS 2062 E350 Tubes supplied by BB Infras undergo a multi-stage inspection and testing process before dispatch:
| # | Test / Inspection | Standard / Method | Acceptance |
|---|---|---|---|
| 1 | Chemical Composition (OES) | ASTM E415 | Per IS 2062:2011 E350 Table 1 |
| 2 | Tensile & Yield Strength | ASTM E8 | ≥490–630 MPa / ≥350 MPa min |
| 3 | Elongation | ASTM E8 | ≥22% min |
| 4 | Hardness (HB) | ASTM E10 | Per standard max |
| 5 | Hydrostatic Test | IS 2062:2011 E350 / ASME B31.3 | Leak-free at test pressure |
| 6 | Dimensional Inspection | ASME B36.10M | Within tolerance |
| 7 | Visual & Surface | ASTM A530 / MSS SP-55 | Free from defects |
| 8 | Ultrasonic Testing (UT) | ASTM E213 (on request) | No sub-surface defects |
| 9 | PMI (XRF) | ASTM E1476 (on request) | Grade confirmation |
Storage & Handling Guidelines
- Store on wooden dunnage or pipe racks — never directly on concrete to avoid moisture-induced corrosion.
- Stack with appropriate separators; observe safe stack heights to prevent deformation.
- Apply plastic end caps or plugs to all open ends to prevent ingress of moisture, dust and insects.
- Keep material dry and ventilated; store under cover in humid or coastal climates.
- Use nylon slings or padded lifting hooks — never bare wire rope directly on surface.
- For long-term storage (>6 months), re-apply protective oil coating or wrap with VCI (Vapour Corrosion Inhibitor) film.
- Identify items with heat number tags throughout storage for full MTC traceability.
