15 صفحه اولInvestigation on the Failure of Desal Condenser Tubes of Jeddah
Cupronickel 90/10 alloy has been used world wide as a standard material in heat recovery tubes. The alloy exhibits excellent service characteristics and can also withstand flow up to 3.3 m / sec of seawater. This alloy (Cupronickel, 90/10) was used in the construction of Jeddah IV heat recovery section of desal condenser tubes. Jeddah IV desal unit has 4 modules, each module consists of 21 stag...
متن کاملA Uns S32654, a Stainless Steel for Condenser Tubes
The new superaustenitic stainless steel UNS S32654 (Avesta Sheffield 654 SMO) is proposed for condenser tubes in desalination and power plants. A number of tests illustrating its corrosion resistance in a variety of chloride containing environments are being reviewed in terms of pitting, crevice corrosion and stress corrosion cracking. Relevant mechanical and physical properties are described. ...
متن کاملSimultaneous hydroforming of bulge- and T-zone in 304 stainless steel and 70/30 brass tubes
Hydroforming process is largely used for the production of tubular parts in various industries, and has advantages such as less weight, higher quality, more strength and fewer production cost compared to the conventional methods of production. The aim of this study is forming a tube-shaped part with a special geometry that has both bulge- and T-zones with tube hydroforming process. The forming ...
متن کاملFailure Probability and Remaining Life Assessment of Reheater Tubes
In this study, a real and significant industrial problem in a steam power plant was investigated. Reheater tubes in boilers are under the creep and the fireside corrosion mechanism that cause some of them to fail. Since the estimation of probability of failure (PoF) and remaining life (RL) is expensive and time consuming in the deterministic methods, in this work they were evaluated using struc...
