For pressure vessels, changing their intended use reduces the associated risks – what procedures are required?
Thread Content
If a pressure vessel has its intended use altered, thereby reducing the associated risks, it is no longer considered a pressure vessel according to the regulations governing such vessels. What procedures are required in this case? Cancel it?
If a pressure vessel is no longer classified as such, cancellation procedures must be carried out. The specific procedures may vary by region; it is recommended to consult the relevant local departments or agencies for their guidelines and follow those procedures. .
Relevant procedures must be followed in accordance with the \"Fixed Capacity Regulations\".
If its purpose, operating conditions, or location of use are changed, it remains a pressure vessel; in such cases, a change must be registered with the local quality and technical supervision authority. If it is no longer a pressure vessel, then it should be registered with the local quality and technical supervision authority for cancellation, and managed as a vessel under normal pressure conditions.
A change must be applied for at the authority that issues the registration certificate (the department/section for special equipment in the local market supervision bureau). If it also constitutes a pressure vessel, then it is considered a modification to such a vessel; in such cases, an inspection process for overseeing the modification is required, and a certificate verifying this oversight inspection must be obtained. If it is no longer considered a pressure vessel, the original registration certificate shall be cancelled.
