Formulas for selection:
Hmin = 0,5 x (OD1 + OD2) + 70 [mm]
A = √2 x Hmin [mm]
Height determined according to table LINK
where:
OD1 – outer diameter of the main line casing pipe
OD2 – outer diameter of the branch casing pipe
od1 – outer diameter of the main line steel pipe
od2 – outer diameter of the branch steel pipe
