Thread Content

Hello, experts. I would like to ask you that in the table regarding the dimensions of welded branch fittings specified in the MSS SP-97 standard, the A value for each wall thickness category is given in two forms: reducing and full. What do these two values mean respectively?

All represent that A’s height: reducing means reduced, while full means complete

Hello, I know what this word in English means. What I want to ask is: in what situations should the shortened form be used, and in what situations should the full form be used? If you know, please tell me. Thank you

Personally, I understand that reducing is used in situations where high full penetration is required, that is, under high-pressure conditions. The opposite case uses full

Does the original poster know the difference between the two now?
