Pipelines laid over long distances in the onshore environment may be affected by excessive straining, corrosion, collapse of soil and other third-party damages. Small chronic leaks cause severe safety environmental effects if left undetected for a time. Any potential leaked water source not detected time could lose considerable volume under ground. Thus, this study aims to determine leakage pip...

Applying the modular technology of developing of the problem-oriented extensions of a CAD system to a problem of automation of creating of the axonometric piping diagrams on an example of the program system TechnoCAD GlassX is described. The features of realization of common operations, composition and realization of special operations of a designing of the schemas of the special technological ...

In accordance with 10 CFR 50, Appendix A, General Design Criteria 4, the Nuclear Management Company, LLC, (NMC) requests Nuclear Regulatory Commission (NRC) review and approval to exclude the dynamic effects associated with postulated pipe ruptures from the Kewaunee Nuclear Power Plant (KNPP) licensing basis. This request is for portions of the KNPP Residual Heat Removal (RHR), Accumulator Inje...

Service experience from 27 seawater reverse osmosis (SWRO) plants confirms that there is an evident risk of corrosion if wrong steel grade is used for the high pressure piping. Neither 316L nor 317L possesses sufficient corrosion resistance. Not even highly alloyed grades like 2205 and 904L show reliable service performance. However, no corrosion has been reported for 254 SMO, which has been us...
