Description

This recommended practice offers guidance in the selection of steels for new pressure vessels and the inspection and operation of existing pressure vessels to minimize the probability of brittle fracture. This recommended practice is aimed at preventing brittle fracture caused by low toughness at temperatures below approximately 120°F. Other mechanisms of deterioration are not addressed in this publication.

Both sections of this recommended practice are influenced by the improved toughness requirements voluntarily imposed by several companies for vessels used in refineries and by a few companies for petrochemical plants, natural gas processing plants, and transportation facilities. This recommended practice is also based on the toughness requirements included in the 1989 edition of Section VIII, Division 1, of the ASME Boiler and Pressure Vessel Code. The provision of API Standards 620 and 650 have also influenced the development of this recommended practice.

Little precedent exists for the specification of enhanced toughness for multiple duplicate (or mass produced) vessels, nor for those vessels used in natural resource services (see Section 6 of API 510 for a more complete definition of the latter).

API publications may be used by anyone desiring to do so. Every effort has been made by the Institute to assure the accuracy and reliability of the data contained in them; however, the Institute makes no representation, warranty, or guarantee in connection with this publication and hereby expressly disclaims any liability or responsibility for loss or damage resulting from its use or for the violation of any federal, state, or municipal regulation with which this publication may conflict.
