Chemical Engineering Plants and Related Equipment Sectional Committee, MED 17
FOREWORD This Indian Standard (Second Revision) was adopted by the Bureau of Indian Standards, after the draft finalized by the Chemical Engineering Plants and Related Equipment Sectional Committee had been approved by the Mechanical Engineering Division Council (MEDC). This Indian Standard was first brought out in 1965 and then revised in 1976 to make it more comprehensive and systematic. The first revision was based on DIN 28004 Bl.3. (1971) which has now been revised as DIN 28004 : 1988. Keeping in view the developments that have taken place over these years in the process equipments and chemical plants, it was decided to revise this standard. In this revision, the requirements of Graphical symbols for pipe lines and instruments given in IS 9446 : 1980 are also being covered. Therefore, IS 3232 is retitled as ‘Recommendations on graphical symbols for process flow diagram, piping and instrumentation diagrams’. After the publication of this standard IS 9446 : 1980 shall be treated as withdrawn. Process flow diagrams are widely used in chemical industry as an aid to show basic items of major equipments and their relations to one another in the process scheme. The important flow lines are indicated as connecting items of equipments and help to describe how the process operates. Piping and instrumentation diagrams are used in the chemical industry to indicate all important aspects such as: -
All equipment items All instrument items All pipelines Important aspects such as insulations, slopes, equipment elevations, etc
This second revision of IS 3232 is based on the following:. a) IS 3232 : 1976, b) IS 9446 : 1980, c) Prevailing practices existing in leading design engineering organization in the country, and d) Instrumentation symbols are in line with Instrument Society of America (ISA) stipulations.
