Foreword

This standard rule according to GB/T 1.1-2009 given draft.

This revised standard adopts API591.2008 "valve quality assessment procedures."

This standard is based on API591.2008 re-drafting of this standard and API591.. 2008 compared to the main changes are as follows.

--- With our standard API instead of the standard file normative references;

--- Removed API591.2008 standard terms such as. acceptance criteria, the buyer, quality assurance, etc. These terms are not present standard

Specific terms, this standard has no special meaning;

--- Not used API591.2008 Chapter 5, "factory quality assurance procedures" content, according to China's laws and regulations, technical specifications related

Claim;

--- Not used API591.20086.4.12 bolt hardness and material tensile strength of the relationship described.

The standard proposed by China Machinery Industry Federation.

The standard valve by the National Standardization Technical Committee (SAC/TC188) centralized.

This standard is mainly drafted by. Hefei General Machinery Research Institute, Hefei General Machinery Products Inspection Institute, Suzhou Neway Valve Co., Ltd.,

1 Scope

This standard specifies the petrochemical industry with both valve, closing valves, ball valves, check valves, butterfly valves, plug valves responsibilities valve assessment, Documentation Service

Management, reassessment of valves and other content.

This standard as a measure of the valve manufacturer valve structure and quality assessment procedures, but does not replace the valve factory acceptance criteria.

The standard assessment refers only valve manufacturer has been assessed in its local manufacturing valves, not included in other parts of the plant manufacturing the valve.

Valve other similar structures can be assessed with reference to the requirements of this standard.
