Scope

SY/T 10043-2002 is the English-translated version of 泄压和减压系统指南.

SY/T 10043-2002 is the Chinese standard "Guide for pressure. relieving and depressuring systems". This standard applies to pressure relief and steam pressure systems.

Information provided is used to help choose in the event of a dangerous situation and the pressure relief system is ideal for a variety of devices.

This standard is intended to supplement API RP 520 I refinery pressure relief device to determine the size, selection and installation of the first part of the sizing and selection (fifth edition) prescribed practices, in order to establish a design basis.

This standard is the main reason for the analysis of overpressure, as well as to determine the selection and design of a single release, such as containers, including flare and vent tower processing system provides a guide.

Proposed pipeline-related data and pressure relief system in the standard 5. 4. 1. However, the actual lines should be designed in accordance with ASME (American Society of Mechanical Engineers) B31.

3 or other applicable specifications. Health hazards associated with the operation of pressure relief devices may be relevant. Discussion of specific risks beyond the scope of this standard. Issued on 2002-05-28, in force from 2002-08-01.
