6.This composite pipe has its shell constructed with metal with brackets by point welding U-shape tortoiseshell network in the inner wall and stuffed with rare earth wearable materials making the pipe enjoy better anti-eroding and wear resistant capability.
7.This paper discusses how to improve large taper lining, the steel-fibre liningis improved to be tortoise-shell net structure, to avoid the lining drop and remove a hidden danger.
8.This composite pipe has its shell constructed with metal with brackets by point welding U-shape tortoiseshell network in the inner wall and stuffed with nanometer wearable materials making the pipe enjoy better performance in high-temperature resistance, anti-eroding, acid resistance and wear.
