The main types of temperature would include room, higher, and common temperature. Taking one of the steel pipe of EN 10216 steel pipe for example.

Room temperature: EN 10216 Part 1 produced by non-alloy pipes with specified properties.

Higher temperatures: EN 10216 Part 2 of non-alloy pipes with specified properties.

Used for any temperature: EN 10216 Part 3 of alloy pipes made from fine-grained steel.

Under this situation, this is a necessary topic for discussion about the engineering project with the comparative steel pipes.
