Do plate heat exchangers fall under pressure vessels? Is supervision by the Special Inspection Agency required?
Thread Content
I would like to ask everyone: does a detachable plate heat exchanger fall under the category of pressure vessels? Is it necessary to report to the special inspection agency for supervision? I’m encountering such a problem now; thank you
Inspection is required as long as it falls within the scope of application of the tolerance specifications.
Refer to Article 1.5 of the Fixed Pressure Vessels Regulations: plate heat exchangers fall outside the scope of application of these regulations. China’s standards for plate heat exchangers also do not stipulate that they should be treated as pressure vessels.
There are many types of plate heat exchangers, which are widely used. Some of them are considered pressure vessels while others are not. It is possible to determine whether a device is a pressure vessel by checking the nameplate or design drawings, as these documents contain information regarding whether it is a pressure vessel or not! Execution standard GB16409 – Plate heat exchangers
Right now, the manufacturers tell me that supervision isn’t necessary, while some others say it is, which is really confusing
Not applicable; Article 5 of the exclusion clauses in 1.5 of the \"Solid Content Regulations\" – plate heat exchangers, spiral plate heat exchangers, air-cooled heat exchangers, cooling coils
No, Article 5 of the scope of application in 1.5 of the \"Fixed Capacity Regulations\" explicitly states that plate heat exchangers are not included
Plate heat exchangers definitely fall outside the scope of large-scale pressure vessel regulations; they do not require manufacturing, installation, or periodic inspection.
