HG/T 21594~21604-2014: How can one determine the weight of stainless steel manholes and handholes? Should the weight be based on PL, SO, or WN flanges? !

This is the standard error, which should be listed separately...

Isn’t this error also a bit serious? It doesn’t seem like such an error should occur! !

If the quantity is small, it’s quick to calculate by yourself.

Oh my God, is that even considered standard! ? Can that even meet a standard if calculated by oneself!

Can’t you check it in 20592?
Reply #72015-09-14
I can only go and check it in 20592 myself

Flanges and covers can be looked up, but what about those small components? Why is it necessary to establish standards? ! Hehe
