Do all chemical process pipelines have to be designed by a design institute?

Help! ! Inquiry regarding manufacturers that produce aerosols for household use; 2 new emulsification tanks are to be added, and these are not pressure vessels! The design involves drawing steam and cooling water from the existing valve assembly (non-pressure pipelines, with steam pressure kept below 0.1 MPa). We have completed the PID design, and the contract has also been signed. The client put forward a new request, saying they wanted a blueprint with the design institute’s stamp. Excuse me, is this necessary? Although it falls under the category of chemical pipelines, it is not considered a pressure pipeline. Is it necessary to have it designed and stamped by a design institute?
In our country, all chemical pipeline designs must be approved by a design institute. Even if the pipeline does not fall under the category of pressure pipelines, it must still be designed in accordance with relevant laws, regulations, and standards, and it can only be constructed after being reviewed by a design institute and having its design approved with an official stamp. The requirements put forward by your client are reasonable; you need to contact a reputable design firm to carry out the pipeline design and obtain the necessary approval. .
The original poster should think carefully about what compliance means ? Chemical plants are required to undergo various inspections; if they carry out these inspections on their own and issues such as safety or environmental problems arise, should the regulatory authorities hold them accountable? ?
Thank you for the reply! So where can I find the relevant regulations regarding these matters? There were no such requirements before; the issues raised this year need to be addressed. As for how to address them, funds are also required for that, and it’s necessary to consider whether these costs can be added to the client’s bill
The drawings must be prepared by a design institute with the appropriate qualification level (for example, an institution with a qualification of Grade B or higher in fields such as petrochemicals, pharmaceuticals, or chemical engineering). The requirements for design qualifications can be found on the official website of the Ministry of Housing and Urban-Rural Development.
If it does not fall under pressure pipelines, the regulatory authorities will not supervise it. Refer to TSG D0001 for the scope of regulation. But if what the original poster is referring to involves pressure pipelines, then a design institute will need to prepare the blueprints. If it is confirmed that there are no pressure pipelines involved at all, then it should not be necessary to prepare any documents; for example, in the case of tubing used in chemical processing units, the design institute does not provide any blueprints either.
Don’t pretend to know something you don’t; don’t mislead others.
In our country, all chemical pipeline designs must be approved by a design institute. Does this sentence have a source? It’s very important to find this answer; I’ve been looking for the guidelines these past few days. Coming from a non-professional background, one cannot find answers to many basic questions through schools or the industry; one has to seek out the regulations and standards on one’s own, and figure things out through exploration
