爆破片的应用（中英文）
使用单个安全装置时（主力情况）
When using single safety device;(Primary Case)
当使用爆破片作为唯一安全装置时，ASME 规范应设定为低于最大允许工作压力 (MAWP)，且其尺寸应能够防止压力升高超过 10% 或超过 3psi。
ASME CODE shall be set as lower than MAWP when a Rupture Disc is used as an only safety device, and it should be the size that can prevent increase of pressure over 10% or over 3psi.
使用两个或两个以上安全装置时（二级情况）
When using single more than two safety devices;(Secondary Case)
使用多个安全装置时，只需将一个安全装置的压力设置为低于最大允许工作压力 (MAWP)。除火灾情况外，其余安全装置的设定压力不得超过最大允许工作压力 (MAWP) 的 105%。
压力容器的尺寸应能够防止压力升高超过最大允许工作压力 (MAWP) 的 16% 或 4psi。
When multiple devices are used, only one safety device needs to be set to have lower pressure than MAWP. The pressure set for the rest of safety devices cannot exceed 105% of MAWP except FIRE CASE.
Pressure container shall have the size that can prevent increase more than 16% of MAWP or 4psi.
与安全阀组合使用时；（组合情况）
In case of the combination with safety valve;(Combination Case)
在保证足够泄放能力的情况下，可在安全阀与工艺装置或安全阀出口之间安装爆破片装置。该装置可防止压力安全阀泄漏，并保护安全阀免受腐蚀。当爆破片装置安装在入口侧时，实际泄放能力应为安全阀标定泄放能力的90%（在相同条件下进行测试时，实际泄放能力视为合格）。
当爆破片装置与安全阀组合使用时，爆破片的破裂不应影响安全阀的功能，并且安全阀与爆破片之间应留有足够的间隙，或应安装压力检测装置（压力表、过流V/V或压力开关）。
Rupture Disc device can be installed between safety valve and process or exit of safety valve when sufficient discharge capacity is guaranteed. It prevents leakage through pressure safety valve and protects safety valves from corrosions. When it is installed at the entrance side, the actual discharge capacity is considered as 90% of the discharge capacity marked at the safety valve (When it is tested under the same conditions, the actual capacity is acknowledged).
When it is combined with safety valve, the rupture of the Rupture Disc shall not interfere the function of safety valve, and there should be enough space between safety valve and Rupture Disc or a device that can detect pressure (manometer-pressure gauge, Excess Flow V/V, or Pressure Switch).
当其用作防止外部火灾的安全装置时（外部火灾情况）
When it is used as a safety device against external fire;(External Fire Case)
如果存在火灾或意外的外部热源等其他危险因素，则应配备额外的泄压装置以防止压力过高。在这种情况下，泄压装置应具有足够的泄压能力，以防止压力升高超过最大允许工作压力 (MAWP) 的 21%。设定压力不得超过最大允许工作压力 (MAWP) 的 110%。
当未连接永久供气接口的压缩液化气体在室温下储存时，泄压装置应能够保护压力容器免受火灾等外部热源的影响，并且泄压装置应能够防止压力升高超过最大允许工作压力 (MAWP) 的 20%。
If there are additional hazardous elements such as fire or unexpected external heat, there should be additional pressure discharge device to protect from the exceeding pressure. In this case, it should have sufficient discharge not to increase pressure over 21% of MAWP. Set pressure shall not exceed 110% of MAWP.
When compressed liquid gas without permanent supply connection is stored in room temperature, it should be able to protect pressure container from external heat sources including fire and the pressure discharge device should be able to prevent pressure increase over 20% of MAWP.
※ MAWP（最大允许工作压力或设计压力）：不影响容器原有性能的最大压力。常压下为最大压力，真空下为最小压力。
MAWP (Maximum Allowable Working Pressure or Design Pressure): maximum pressure that the original performance of the container is not affected. Under normal pressure, it means maximum pressure, while it means minimum pressure in vacuum.
