Combination of safety valves and burst discs as safety devices – requirements regarding the distance between them.
Thread Content
Hello, everyone: The new version of \"Combination of Safety Valves and Burst Discs\" will implement GB38599-2020. The scope of application of this standard is for series combination structures in which the distance from the outlet side of the burst disc safety device to the inlet side of the safety valve is no more than 5 times the pipe diameter. This raises the following two questions: 1. What standards should be applied when the distance between the two is greater than 5 times the pipe diameter? 2. Is it true that the ratio between the two cannot exceed 5 times the pipe diameter? What are the consequences if this ratio exceeds 5 times the pipe diameter? 3. What standards are used for the calculation of combined devices? Is the calculation for a combined device the same as that for a single device? I would be extremely grateful if someone who knows the subject could help explain it to me!
Perhaps to meet the requirement that the distance from the safety valve inlet to the protection device should be as short as possible? Whether it’s a safety valve or a burst disc, in principle they should be placed close to the equipment being protected, right?
4.3.2.2 When the burst disc safety device is installed on the inlet side of the safety valve, the following requirements shall be met: b) The nominal diameter of the burst disc safety device shall be no smaller than the diameter of the pipe on the inlet side of the safety valve, and it shall be installed within 5 times the pipe diameter from the inlet side of the safety valve; furthermore, the pressure loss in the pipeline at the inlet of the safety valve (including that caused by the burst disc safety device) shall not exceed 3% of its set pressure
