Experiment study on closured weld joint type of pressure pipes

It is analyzed that the welding properties of pressure pipe for water power station and welding technology actuality of pressure pipe both at home and abroad and design one set of automatic welding scheme-solid core wires mixed gas protective pulse automatic welding aimed at the existed problem among automatic welding technology of pressure pipe.

Diameter selection of pressure steel pipe of small type hydropower station of diversion;

At present, in the water conservation and hydroelectricity general estimate budget stipulation, PCCP pipe and pressure steel pipe are taken into engineering investment as construction engineering fee and erection engineering fee separately.

This paper applies two mathematical theories: optimization design and fuzzy mathematics, to exposed pipe of pressure steel pipe of hydropower station for forming a complete and rational design mathematics model—fuzzy optimization design mathematics model of the film stress area of exposed pipe of pressure steel pipe of hydropower station.
