IMPORTANT:
Rhosonics does not take responsibility for any of these torque values, they're theoretical values. These
bolt torque values are intended for use as guidelines only and are based on ideal conditions, perfect
flanges, flange alignment & new well lubricated bolts/nuts. Torque values are based on using weld-neck
flanges and lubricated stud bolts with a 0.16 friction factor.
Torque values for other gaskets, please contact your gasket supplier.
2.4 Weldolet installation (SDM-2 or SDM-3)
A weldolet is a metal piece which should be welded on an existing pipe. Please follow the next procedure
to mount a weldolet.
Drill a hole of Ø36 mm in the process pipe, comply with vertical and horizontal installation
conditions. Make sure no burrs are left inside the pipe.
Hole Ø36 mm in a vertical pipe.
Mount the weldolet in the drilled hole. Make sure the weldolet is aligned with the pipe. In
addition, make sure the inside of the pipe is flush with the weldolet.
Weld the weldolet on the pipe. Make sure the weld is liquid-tight all around.
