UPGRADING SISTEM PEMIPAAN PADA INSTALASI PENGOLAHAN LIMBAH PABRIK BAJA BERDASARKAN ASME B31.3

Abstract

A steel industry requires upgrading the piping installation at the beginning of wastewater treatment systems. Waste water  treatment  system early  wear  of  piping systems and  basically  an  industrial production process want that goes running with a good system and in accordance  with the planned standards. In this research, stress analysis with manual calculations and using CAESAR II software. The pressure in the pipe or piping system generated as a result of such loads, sustained loads and loads due to expansion. From the simulation can be seen that the safe limit pipe materials used in piping  systems wastewater  treatment  of  steel  plant  to  the  stress  resulting  31.2  MPa  and  the allowabled stress  266.5 MPa. Theoretical calculations and by simulation software obtained error on Bending Stress (Sb) at 2.02%, and Displacement stress (SE) at 2.02%. By providing variations input temperature of pressure 89.6 kPa, temperatures are not allowed greater than 246oC, and temperature

46 ° C pressure variations are not permitted huge pressure of 15089.6 kPa past the allowable stress that the pipe will experience fatigue failure (exhaustion).
