Why is the wall thickness thicker for smaller diameters, while it is thinner for larger diameters? Is SCH80 used for small pipe diameters and SCH40 for large ones? ?
Why go and ask for answers that can be found simply by searching? Are you that lazy? http://bbs.hcbbs.com/forum.php?mod=viewthread&tid=1298503 On floor 13, the user \"Desert Fish\" provided the correct method
I think it's due to the strength and corrosion allowance.
Damn it, OP – you’re asking such a childish question again. Who told you that SCH40 is thinner than SCH80? Figure out what SCH means first, okay?
Check SH/T3405 or ASME B36.10M – either one will give you the answer!
Bro, who told you that SCH80 is thinner than SCH40? The wall thickness of pipes needs to be calculated carefully; it can’t be decided arbitrarily. It depends on factors such as the properties of the medium, the required corrosion margin, and the pressure rating. Take a good look at the standards.
