If the manufacturer and the installer of the pressure vessel are the same entity, is it still necessary to inform the special inspection agency about the installation?

According to Chapter 6 of TSG21-2016 on supervision and inspection, no supervision inspection is required for installation

It’s good that installation doesn’t require supervision, but it seems that reporting is still necessary to facilitate **the management of pressure vessel equipment**

Just submit a report; it’s now possible to do so online as well.

1. The qualification for pressure vessel installation is no longer issued. For pressure vessel installation, the qualifications for pressure pipeline or boiler installation can be used instead； 2. Supervision and inspection are not required for the installation of pressure vessels ； 3. Inform them that it is not at the special inspection office, but at the local supervision department ； 4. Will the special inspection agency send someone over after being informed? See point 3 ； 5. The manufacturing and installation of pressure vessels can be carried out by the same company; there is no need to obtain separate qualifications, and pressure vessel installation qualifications are no longer issued. 6. Others: Other elementary school students who are not reading can continue to ask questions.

The Special Inspection Institute is not a regulatory body; it is a professional institution, just like design firms, manufacturing units, user organizations, and installation companies. I still mean the same thing: just because an organization is professional doesn’t mean it will provide professional advice; it merely has professionals there. Even inspectors at special inspection agencies who have been working in this field for decades can ask extremely unprofessional questions that are both ridiculous and leave one with no answer.

TSG R7004-2013 \"Rules for Supervision and Inspection of Pressure Vessels\" has been repealed and is no longer in force. What was previously considered on-site welding and assembly as part of installation inspection is now regarded as on-site manufacturing, falling under manufacturing inspection. Written notification regarding installation activities is required; this is a legal obligation, and there is no dispute over that. The statement that supervision during installation is cancelled is inaccurate; TSG 21-2016 6.1.1 states that no supervision is required during installation, and the repealed technical specifications state the same thing. (1) Units engaged in the installation, modification, or major repair of pressure vessels must be entities that possess the appropriate qualifications ； Installation, modification, and repair units shall establish a quality assurance system in accordance with the requirements of relevant safety technical specifications and ensure its effective operation; such units and their principal responsible persons are accountable for the quality of the installation, modification, and repair of pressure vessels ； (2) Installation, renovation, and repair units shall strictly comply with laws, regulations, safety technical specifications, and technical standards ； (3) The installation, modification, and repair unit shall provide the user unit with technical documents such as construction plans, drawings, and certificates of construction quality ； (4) Before the installation, modification, or major repair of pressure vessels, the entity carrying out such work shall provide written notice to the special equipment safety supervision department in the location where the vessels are used. General Administration of Market Regulation [2019 No. 3], “Catalogue of Permits for Special Equipment Manufacturing Entities”. Note: Pressure vessel manufacturing entities may design and install pressure vessels of the same manufacturing class as well as industrial pipelines connected to such pressure vessels (except for those conveying flammable, explosive, or toxic substances; there are no restrictions regarding the length or diameter of these pipelines) ； Boiler installation units or pressure pipeline installation units with installation qualifications at any level can carry out the installation of pressure vessels. Therefore, pressure vessels need to be installed, and they must be installed by qualified entities.

The definition of “installation” is specifically explained in regulations that were abolished many years ago. From the current responses provided by the General Administration, it can be determined what characteristics installation possesses: 1. Mobility； 2. Include the cost of setting foot bolts.

Pressure vessel manufacturing units possess the appropriate qualifications for installing pressure vessels of that category; notification must be submitted at the location where installation takes place, but there are no requirements for supervision or inspection during the installation process
