Pressure Vessel Use Permit

Pressure vessels must be manufactured by qualified entities, and complete inspection documents are available upon leaving the factory. After installation, they must be reported to the local pressure vessel regulatory authority to complete the necessary procedures； In the second case, a retest is required before proceeding with the procedures! It’s all for safety reasons.

Our practice here is as follows: for pressure vessels that were manufactured within the last three years, a usage certificate is obtained after installation, and the date for the next inspection is set as the manufacturing date plus 3 years； For those manufactured within the past three years, inspection should be commissioned first; once the inspection is successful, installation can proceed and a usage certificate will be issued. The next inspection date will be three years after the date of successful inspection.

For commissioned testing, which department should be entrusted with the testing? What needs to be checked?

TSG21-2016, P63: The answer is clearly given in the first sentence – before putting it into use or within 30 days after use. The procedures vary from place to place; in some areas, it is necessary to give prior notice before proceeding, followed by inspection before use ； In some places, the registration authority issues the certificate directly; you should consult the local market supervision bureau where the equipment is located for details.

In accordance with the requirements of TSG08-2017 \"Regulations on the Management of the Use of Special Equipment\", prior to the installation of special equipment, it is necessary to submit an installation notification to the local authorities responsible for the supervision and management of special equipment. Registration must also be completed within 30 days before and after the equipment is put into use. 1. If the project has been suspended for several years and the installation has not been completed, an installation notification must be submitted again before work resumes. At that time, the supervision authorities will likely require a comprehensive inspection, after which registration can be carried out in accordance with the procedures outlined above. 2. If the installation has been completed, it is necessary to contact a party qualified to conduct a comprehensive inspection of the special equipment, and use the inspection report along with relevant factory documents and installation records to proceed with the registration process.

According to the regulations, within 30 days before and after installation, failure to inform in case of installation will constitute a violation of the law. Under normal circumstances, it is to inform, inspect, and obtain the certificate. This is a procedure recognized by the oversight authorities
