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 2appendixes.

The main technical contents in this Guideline include material selection for design of equipment and piping in units processing sulfur 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 3096-2001 and SH/T 3129-2002 were Integrated to form the Material Selection Guideline for Design of Equipment and Piping in Units Processing Sulfur Crude Oils（SH/T 3096-2012）；

—The lists of materials recommended for major equipment and pining in hydrofining unit，gas desulfurization unit，sulfur recovery unit and solvent regeneration unit were added；

—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；
