Sockolet can be done like this:

-main line:

from 10 to 20

20 SIF weldolet

from 20 to 30

- branch

from 20 to 1000 perpendicular on main line half dia of main pipe a rigid without weight

1000 to 1010 the branch element with branch dia
1000 SIF socket weld

Please note that option 8 and 9 are socket weld not sokolet therefore a 2 element connection. This explain the way of previous model.
