WHAT IS SRP PIPE?
An SDR solid wall pipe is designed to contain internal pressure (10-20 bar). This requires very thick walls to resist the bursting forces.
An SN profile pipe needs only resist external buckling forces.
For gravity pipe you only need a SN rated profile pipe, no bursting strength is required.
A profile pipe works by using the height of the profile to maximise the Distance of Inertia and the Moment of Inertia from having more mass at a distance to create the same mechanical strength as a solid wall pipe but with only 20%-30% of the weight. The savings are significant:

INFRAPIPE can easily be continuously welded like solid wall pipe, or bolted
