Assembling evacuation pipe joints
Functions of the evacuation pipe joints
Evacuation line joints have three functions:
● To seal the junction of two pipes of the same diameter;
● To hold the pipe sections together;
● To withstand the pressure of manure inside the line.
Types of evacuation pipe joints
GEA Houle manufactures 8 different types of joints for quick assembly of PVC
and steel pipes. GEA Houle joints cannot dislocate when properly installed.
The installer who chooses to use concrete thrust blocks must refer to
local authorities for proper specifications regarding the size, the
orientation and the spacing of the blocks.

● Before connecting pipes, apply vegetable grease inside each female pipe
end;
● According to the joint type, use all components required to assemble pipes
together;
Note!
Refer to the drawing in the following table that corresponds to your
assembly.
● Once pipe joints assembled, tighten moderately the 4 threaded rod nuts to
prevent the joint from dislocating. Tighten each nuts at the same torque.
Warning!
Do not overtight threaded rod nuts. Overtight nuts will damage the pipe
joint sealing. The threaded rods function is to prevent pipe joint from
dislocating, not to tight them together.
