Surge Analysis for Tata Steel Limited (TSL) at JODA,Odisha – FLSmidth LIMITED

The study carried out pressure surge analysis for 8” and 5 km long slurry export lines in order to evaluate the maximum transient pressure surges in various foreseeable mal-operations.

Iron ore tailings thickened slurry transfer pipeline is a slope pipeline of 12” dia of 6 meters length (Pump Suction), 10” dia of 32.1 meters length (Pump Discharge) and 8” dia of 5063 Meters transporting Iron ore tailings thickened slurry.

The purpose of this study is, 

  • To develop steady state model and perform Hydraulic study of Iron ore tailings thickened slurry transfer pipeline.
  • Perform Transient Analysis and estimation of surge pressure for Export Pipelines due to sudden pump trip and closure of suction/discharge/pipeline valves.
  • To provide surge mitigation measures, when the surge pressure exceeds the maximum allowable surge pressure.
