Selection of jacketed tee fittings

2018-04-11View Original

Thread Content

The SHT 3040 Design Code for Pipelines in the Petrochemical Industry specifies the types of tees for jacketed pipe fittings. However, unlike the flanges used in jacketed pipes, which have a separate standard (SH/T 3426), should the standard number GB/T 12459-2017 be indicated in the material table for tees, or should it be left blank?

For jacketed tee connections, tube splitting is generally used; GB/T 12459-2017 does not provide specifications for the dimensions of the split tubes

Yes, that’s why I want to ask how to choose this standard!

We used to have a practice of directly purchasing standard tees and then fabricating split tubes on site

Oh, I see. Got it, thanks!
