摘要
从国内的实际情况出发,在研究陕京、忠武及西气东输输气管道管材设计的基础上,从管材化学成分、钢材冶炼(真空脱气、钙处理)、晶粒度、硬度、非金属夹杂物形状等方面提出抗氢致开裂(HIC)管道用钢的设计要求。
The pipe designs of Shanjing,Zhongwu and West-to-East natural gas transmission project are analyzed.According to the actual situation in China,the design demands for design anti-hydrogen induced cracking（ HIC） pipeline steel are then put forward from the aspect of the chemical composition of the pipe,steel smelting（ vacuum degassed calcium treatment）,grain size,hardness,shape of nonmetallic inclusions,etc.
