What is the nominal range for butt-welded branch pipe bases? ? ?
Thread Content
The welded branch pipe fittings can go up to DN600, but usually such a large size isn’t chosen? I would like to ask, what diameter range do people generally choose for butt-welded branch pipe bases?
The branch pipes are generally 2" or DN50 or less. Of course, there are standards that are larger than 2 as well; you can choose those as well. Each company has its own regulations.
I looked at the ranking tables for a few other compounds; 80 is a commonly used value, but I also saw values of 150. I haven’t seen any higher values
I'm talking about the butt-welded branch pipe base. Generally, larger sizes use tees.
DN250 branch pedestals are also in use. The requirements of each design institute or client are not necessarily the same. You can take a look at the screenshot below, which shows the pipeline branch table of one of the top 50 companies in the world.
It has reached 500 – quite rare, but representative and well-supported
What I’ve come across are also 100, 80, 65, 50. I’ve never seen one that’s this big!
Large-diameter butt-welded branch fittings are already cheaper than tees, and they are still usable
May I ask if there are any relevant standards?
