Plant Engineering114 End of curve power requirement (to determine motor rating) End of curve power requirement (to determine motor rating) http://www.cheresources.com/invision/topic/11994-standby-centrifugal-pump-driver-sizing/ 지금까지 모터 Rating은 API 610 (11th ed.)의 7.1.4 항목에 따라서만 결정되는 줄 알았다. 하지만 역시 이는 minimum requirement일 뿐이었다. 그동안 Vendor 견적에 표시된 파워가 과도하다고 생각했던 것은 판단 미스. 최근 진행중인 프로젝트의 FEED에 다음과 같은 언급이 있었다. "Motor rating of pumps shall cover end of curve power on pump performa.. 2014. 11. 28. ASME B73.1 and ISO 5199 - A Quick Comparison ASME B73.1 and ISO 5199 - A Quick Comparison https://www.wilfley.com/blog/asme-b73-1-and-iso-5199-a-quick-comparison/ The widely referenced centrifugal pump standard known as ASME B73.1 can trace its origins as early as 1955, when efforts to develop chemical pump standards began. This later evolved into the American Voluntary Standard in 1962 and, in conjunction with a similar Hydraulic Institut.. 2014. 11. 19. FRP Pipies (GRP/GRE/GRV Pipes) http://www.adpf.ae/docs/about_frp.html About FRP Pipies RTRP stands for Reinforced Thermosetting Resin Pipe and FRP stands for Fiberglass Reinfoced Plastic Pipe. FRP is a composite material consisting of a thermosetting polymer, often a type of polyester, reinforced with glass or other fibers. Glass fibers provide strength and stiffness to a composite material. Different types of resins are used.. 2014. 11. 14. Definitions of Spare Part Commissioning and Start-up Spares Parts Commissioning and start-up spares parts, cover the type and number of spares which will be required prior to and during the commissioning and start-up period. 2 Year Operating Spares Operating spare parts are those required for day-to-day maintenance for the initial 2 year of operation. These parts may fail in use, if there is no planned replacement interv.. 2014. 11. 7. Pipe Roughness Pipe Roughness For all claculations of pressure drop, the following pipe roughness values should be used: Pipe Roughness for Typical Materials Material Roughness Carbon Steel (CS) - Process 0.05 mm Stainless Steel (SS) 0.05 mm Titanium and Cu-Ni 0.05 mm Glass Fiber Reinforced Pipe (GFRP) 0.005 mm Polyethylene, PVC 0.005 mm 2014. 9. 30.
