Construction

20# steel pipe, generally 20 seamless steel pipe, the strength is slightly higher than 15 steel, rarely quenched, no temper brittleness.

ASME B16.5 Carbon Steel Class 150 Blind Flange is a carbon steel flange that meets ASME B16.5 standards with a pressure rating of Class 150 and is used for blind end sealing.

The hot expanding steel pipe is hot expanded seamless pipes, which is relatively low density but the contraction of the strong steel pipe (seamless pipe) can be referred to as thermal expansion.
