Questions regarding Article 7.1.4 of the Code for Fire Protection Design of Petrochemical Enterprises
Thread Content
Does the mandatory provision 7.1.4 of the fire protection code, which states that pipes must not pass through devices that are not related to them, mean that there cannot be pipes in the ductwork within a device that are not used by that device or that do not carry materials supplied by that device? Specific to a certain project, Unit A supplies Material A to Units B, C, and D. Apart from this, there is no other material flow between Unit A and any of Units B, C, or D. Meanwhile, there are material flows of B, C, and D between Units B and C respectively, as well as between Units B and D. The question at hand is whether Materials B, C, and D can pass through Unit A when moving between Unit B and Unit C One view is that A supplies raw material A to devices B and C respectively; since these are related devices, materials B, C, and D can still pass through device A’s pipeline, even though they only move between B and C. Another view is that although Unit A supplies raw material A to Units B, C, and D respectively, the materials B, C, and D between Units C and D have nothing to do with Unit A and cannot pass through Unit A’s pipeline system. Finally, since Party A supplies raw material A to Party B, if Party A and Party B are regarded as two monomers or units of the same facility, can the materials between Party B and Party C pass through the pipelines of Party A’s facility in such a case?
It’s to be understood literally; it has nothing to do with that. Since you’ve shared materials with each other, it must be related after all. So there’s no violation.
If Party A supplies material A to Party B, and also supplies material A to Party C, then can the material B that Party B sends to Party C pass through Party A? Is that how it works? I understand that the specification refers to the relevance between pipes and devices, not between devices themselves. Whether Pipe B is related to Device A depends on whether Device A uses that material, or does it depend on whether the two devices are related to each other?
I’d like to learn about it; I also seek advice from experts.
