　　中文名称：低温用锻制碳素钢和合金钢法兰规格

　　英文名称：Standard Specification for Forged Carbon and Alloy Steel Flanges for Low-Temperature Service

　　原文名称：Standard Specification for Forged Carbon and Alloy Steel Flanges for Low-Temperature Service

　　范围：This specification covers forged carbon and alloy steel flanges intended primarily for petroleum and gas pipelines in areas subject to low ambient temperatures. Eight grades, four yield-strength classes, and three different notch toughness levels are included. All material shall be heat treated by annealing, normalizing, precipitation hardening, quenching-and-tempering, normalizing-and-tempering, normalizing-and-precipitation hardening, or quenching-and-precipitation hardening. A chemical heat analysis shall be made and conform to the requirements as to chemical composition specified. The material in the weld neck shall conform to the mechanical property requirements specified. Hardness test, impact test, ultrasonic test, tension test, and hydrostatic test shall be made to conform to the specified requirements.
