where:: N = Non-Upset tubing (T & C); U = External Upset tubing (T & C)
Weight per unit calculation formula:: w = (O.D. - W.T.) x W.T. x 0.0246615 (kg/m); w = (O.D. - W.T.) x W.T. x 10.68 (lb/ft)

Ceramic Lined Composite Pipes

SHS (Self-propagating High-temperature Synthetic process) ceramic lined steel pipe and elbow create a new generation of abrasion and corrosion resistant engineering pipeline. Hoop strength is the resistance against radial pressure. The strength of the ceramic -lined steel composite pipe is 300 to 500MPa.
