New API 610 11th edition (ISO 13709 2nd Edition) includes changes intended to improve pump reliability
Updates to global specifications address pump reliability and much more
Whenever a new edition of a global specification such as the International Organization for Standardization (ISO) or the American Petroleum Institute (API) is released, there is often confusion about the details and rationale of the changes made. The article What is new in API 610 11th Ed. (ISO 13709 2nd Ed.)? describes the changes made and how those changes can impact pump reliability.
The article addresses three significant changes:
• The addition of Annex K Section K.1 Shaft Stiffness Guidelines for Overhung Pumps
• The addition of Annex K Section K.2 Bearing “system” life consideration for OH2, OH3, BB1, BB2 and BB3 pumps
• The expansion of Torsional analysis, rewritten to explain when each type of analysis is required.
Other additional changes are also highlighted.
