A study of the possibility of lowering the weight and reducing the wall thickness of large-diameter pressure pipes

摘要

An attempt has been made to replace a thick-walled pipe of large diameter (oyer 500 mm) with a thin-walled pipe of large diameter, reinforced with glass fibre mesh. It has been shown that, with single-layer reinforcement, it is possible to lower the weight of the pipes by 50% for pipes of up to WOO mm diameter while retaining their hydraulic strength.
