Foreword

According to the requirements specified in the Plan for Developing Professional Standards in 2008(Document Number:[2008]No.1242)issued by the General Administration Office of National Development and Reform Commission,this Guideline is revised by its development team based on wide and intensive investigations and studies made,practices summarized,comments requested as well as references to international codes and advanced foreign standards.

The Guideline comprises 6 chapters and 2 appendixes.

The main technical contents in this Guideline include material selection for design of equipment and piping in units processing acid crude oils.

This Guideline is an integration of and a revision to the Material Selection Guideline for Design of Major Equipment in Key Units Processing Sour Crude Oil(SH/T 3096-2001)and the Material Selection Guideline for Design of Major Piping in Key Units Processing Sour Crude Oil(SH/T 3129-2002).Major technical contents revised include:

—SH/T 3096-2001and SH/T 3129-2002 were integrated to form the Material Selection Guideline

for Design of Equipment and Piping in Units Processing Acid Crude Oils(SH/T 3129-2012);—The List of Materials Recommended for Major Equipment in Fluid Catalytic Cracking Unit is

deleted,and the List of Materials Recommended for Major Equipment and Piping in Hydrofining Unit is added;

—The Figure A.4:Susceptibility of Caustic Cracking in Carbon Steel,Table A.5:Annual High Temperature Oxidation Corrosion Rate of Metal Materials and Table B:Cross Reference for Common Metal Materials were added;

China Petrochemical Corporation(Sinopec Group)is in responsible for the administration of this Guideline,Sinopec Technical Center for Static Equipment Design and Engineering is responsible for its routine management,and Sinopec Luoyang Petrochemical Engineering Corporation is tasked for the interpretation of specific technical contents.If any comments and recommendations are proposed in implementation of this Guideline,please send your comments and recommendations to the routine management organization and chief development organization.
