Friction factor of spiral welded pipe
Spiral welded pipe friction adhesion theory is now widely accepted, in the static friction, the actual contact area is proportional to the load. And when the sliding friction, we must consider the presence of shear force, then, increasing spiral steel actual contact area results from the normal l...Read more -
