Pressure equipment modification
Thread Content
I have a normal-pressure titanium reaction tank with a volume of about 20 cubic meters. Due to process requirements, I want to change it to a low-pressure reaction tank. Is there anyone with expertise who can design and modify it?
Just calculate the strength according to the design procedures of the pressure vessel.
Check it according to the design conditions. If there are local problems, consider strengthening it. If the overall wall thickness is not enough, just make a new one.
If some parts involve welding, are there any special requirements? Or should other sealing forms be used?
In addition to meeting the requirements in terms of strength, it should also meet the relevant requirements of the capacity regulations. Personally, I think it is not feasible. It used to be an atmospheric pressure vessel, and there were no qualification restrictions on manufacturing. But now it needs to be changed to a pressure vessel, and there are requirements for manufacturing qualifications. The original manufacturing documents may not necessarily meet the requirements for pressure vessels. These problems may not be solved. Even if the strength can meet the requirements, it may not be able to pass the procedure for obtaining the pressure vessel use certificate. It is recommended to consult the special equipment supervision department, and it is best to follow their opinions.
It's hard to say. It depends on the specific conditions. I don't know how many specific parameters there are. There is no way to calculate it. But 20 liters is no longer a small thing. If you can save it, just save it.
There is a difference between the design of atmospheric pressure vessels and the design of pressure vessels. I haven't looked at the titanium container standards carefully. For steel containers, the standards followed are different. Specifically, there are differences in allowable stress, manufacturing, and inspection requirements. It must also comply with regulatory requirements
I seriously agree with the fifth floor's opinion. Container modification is a part of container management, and the provisions in the "Container Regulations" and "Regulations" are very clear. Atmospheric pressure vessels cannot be converted into pressure vessels. This is not only a matter of strength verification, but also requires different manufacturing and inspection requirements for normal pressure vessels. It does not mean that the wall thickness is sufficient. Besides, you need to apply for a certificate of use after converting it into a container. What should you do if you don’t have the factory data? Brothers, safety responsibility is more important than Mount Tai!
