Api 610 13th Edition May 2026

I'll help you create a feature related to API 610 13th Edition (Centrifugal Pumps for Petroleum, Petrochemical, and Natural Gas Industries). This is typically used in engineering software, pump selection tools, or compliance checklists.

Below is a conceptual implementation — depending on whether you need a backend validation, frontend checklist, or database structure, I'll provide a modular example. Api 610 13th Edition

3. Testing Requirements (Chapter 10)

| Test | 12th Edition | 13th Edition | |------|-------------|---------------| | Hydrostatic test | 1.5 x MAWP for 30 min | 1.5 x MAWP for 60 min (casing and seal chamber separately) | | Mechanical run test | 4 hours | 6 hours minimum for new pumps; 2 hours for re-rates | | NPSH test | 3 points | 5 points (including two below 3% head drop) | | Vibration test | In-situ filter | Frequency band analysis mandatory (10–1000 Hz) plus bearing housing velocity (≤ 3.0 mm/s RMS) | | Performance test tolerance | ± 5% head at rated flow | ± 4% head; efficiency tolerance tightened to ± 3% | I'll help you create a feature related to

New: Optional Thermal Growth Verification Test for pumps with operating temperature > 250°C (measure cold-to-hot alignment shift). Residual Unbalance: The 13th Edition retains the strict

5. Pump Inspection and Testing (Appendix J)

The requirements for inspection and testing remain a cornerstone of the specification.

  • Residual Unbalance: The 13th Edition retains the strict requirements for impeller and rotor balancing but clarifies the verification methods.
  • Hydrostatic Testing: The duration and pressure parameters for hydrostatic tests have been clarified to prevent ambiguity during factory acceptance testing (FAT).
  • NPSH Testing: Net

2.1 New & Revised Pump Types

  • OH6 (overhung, direct-coupled, low-flow high-head) – clearer definition and specific requirements added to avoid misapplication.
  • BB5 (barrel casing, radially split, between-bearing) – updated rules for high-pressure (≥ 200 bar) services, including nozzle loading and casing bolting.

3.7. Documentation and Digital Data

  • Mandatory electronic data sheets (API 610 Excel format) with pump performance curves in machine-readable form (e.g., CSV or HDF5).
  • Vibration data logs during factory acceptance test (FAT) must include full spectral analysis, not just overall amplitude.
