API Spec 6AV1

$82.00 $41.00

Specification for Validation of Wellhead Surface Safety Valves and Underwater Safety Valves for Offshore Service, Second Edition
standard by American Petroleum Institute, 02/01/2013

Category:

Description

This specification establishes design validation requirements for API Specification 6A surface safety valves/underwater safety valves (SSV/USV) and associated valve bore sealing mechanism(s) for Class II and Class III. These classes are intended for use if substances such as sand can be expected to cause an SSV/USV valve failure.

Class III adds requirements for the validation of the valve bonnet assembly inclusive of stem seals and may be selected by the user/purchaser. Validation to Class III also validates the same SSV/USV for Class II in accordance with scaling limitations specified in the document.

The validation requirements in this specification are not represented as duplicating actual well conditions.

API Spec 6AV1

$103.00 $51.50

Specification for Validation of Wellhead Surface Safety Valves and Underwater Safety Valves for Offshore Service, Third Edition
standard by American Petroleum Institute, 07/01/2018

Category:

Description

There are three service classes – Class I, Class II, and Class III – for API 6A surface safety valve (SSV), underwater safety valve (USV), or boarding shutdown valve (BSDV). This standard establishes sandy service design validation for valves to meet Class II and Class III.

Class II is intended to validate the valve bore sealing mechanism if substances such as sand can be expected to cause safety or shutdown valve failure.

Class III adds additional requirements and validation of the bonnet assembly inclusive of stem seals and may be selected by the user/purchaser. Validation to Class III also validates the same SSV/USV/BSDV for Class II in accordance with scaling limitations specified in the document.

The validation requirements in this standard are not represented as duplicating actual well conditions. For actuated valves, validation of the actuator is outside the scope of this standard.
