Linear defects in steel
Steel tube as an inside surface of the tube in the process of hot-rolled wear plug fatigue caused by wrinkling of the short and shallow scratches or the inner tube causes the surface roughness, the system in the subsequent pulling process, the existence of the inner wall of the small tube former ...Read more -
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 -
