Can the lining withstand pipe deflection?
A deflection test conducted in the shop on a 72″ x 5/16″ welded steel pipe section demonstrated the amazing deflection properties of cement-mortar lined steel pipe. A load applied to the top of the section was gradually increased until a total deflection of 13″ on the vertical axis was reached and then gradually decreased with no impairment to the lining or any serious cracks.
