Design of Storage Tank for Hydraulic System in Cold Roll Skin Pass Mill

Abstract

Pressure vessels and piping systems have received an extraordinary amount of attention in recent years. Even storage tanks at atmospheric pressure have been more heavily scrutinized by the Occupational Safety and Health Administration (OSHA, United States), the Environmental Protection Association (EPA, United States) and industries in general.

The design engineer is facing a multitude of adverbs when considering the best approach to a pressure vessel design, piping design or system design program to select the appropriate code, material, orientation, shape etc.

This project aims to design a two saddle supported horizontal cylindrical tank for hydraulic system in Cold Roll Skin Pass Mill at Essar Steel, Hazira.Here main function of tank is to, store and supply the oil to the system continuously.ASME section VIII div I is followed considering storage tank as low pressure pressure vessel and design is done using horizontal cylindrical shell with both end closed with ellipsoidal heads.Saddle design is referred from standard design available in pressure vessel handbook and modify the design for material saving. Both the tank and saddle is modeled in Creo Parametric 2.0 and finite element analyses of saddle is done in ANSYS 14.0.
