3.Pointed to the problems of calculation of abamurus in pressure pipeline,such as the calculation of applied force not make the difference as which was the main force and which was the secondary,form of abamurus was not rational,calculation of abamurs was too complicated,this article put forward the rational form and calculation method for the abamurus in pressure pipeline,not only simple calculation,but also the engineering amount of abamurus was obviously reduced.
4.Leakage and explosion accidents of boiler feedwater pipes operating at 346℃ and 14.7MPa have been analysed and studied.
5.Must have experience managing fire main systems &associated pumps, sprinkler systems and equipment, with knowledge of fire, pressure vessel, electrical codes and occupational safety codes.
6.Relations Between Flow Field and Pressure Fluctuation in Draft Tube of Francis Turbine
7.Cupreous conduit quality of a material sex of hard, compression is strong, although changeless also body leaves in high-pressured condition, not burst; At the same time because its function stability, corrosion resistance is strong, make obstruction of the flow inside the canal lesser, make sure current is expedite already the pressure that eases water to shed pair of tube wall again, this went up to be sure for water supply, OK and long-term safety is used and do not have trouble back at home.
8.And cupreous conduit quality of a material sex of hard, compression is strong, although changeless also body leaves in high-pressured condition, not burst; At the same time because its function stability, corrosion resistance is strong, make obstruction of the flow inside the canal lesser, make sure current is expedite already the pressure that eases water to shed pair of tube wall again, this went up to be sure for water supply, OK and long-term safety is used and do not have trouble back at home.
