What requirements should be specified to the manufacturer when lining steel pipes with PTFE?

As the title says! I don’t know how to explain this to the manufacturer; is there a significant difference between using 2mm and 3mm thick PTFE sheets for lining?

What requirements should be specified to the manufacturer when lining steel pipes with PTFE? This is very simple: first, you need to specify the thickness of the steel pipe and PTFE material, as well as the pressure and temperature. Most importantly, you need to indicate the length of the pipe. However, note that there are usually no standard values for these parameters; instead, they are determined by the manufacturer. It’s best to provide the manufacturer with a diagram of the pipe’s dimensions. If the dimensions are incorrect, it will be difficult to resolve the issue. You can also have the pipe manufactured on-site, install it there, remove it later, stamp it with the required markings, line it up properly, and then return it for installation with the correct identifiers.

Just provide the pressure rating, diameter, length, and design standards. The lining thickness can also be specified according to the customer’s requirements.

Provide the piping diagram and the material properties of the medium! Thickness is a requirement for protecting pipes; it varies! The prices are different!

Isn’t there a molding process? How can I bring this up to them?
