This standard is based on the requirements of (9) Zhongchi Jijianzi No. 42 document SY751087 "Sales System Design" and the revised standard in the indentation format (MAI/T1.11993 (Standardization Guide Unit 1: Drafting and Expression of Standards Part 1: Standard Compilation and Preparation Regulations) and is compiled in the Auto Standard Collection During the revision process, according to the relevant documents of the American national standards ASME ANSIB16.9 and ASV/ANSIB16.28, some clauses of Y717 were newly arranged and revised, and new contents such as "reducing elbow" and "cross" were added to meet the needs of users. This standard will replace Y51 after it takes effect. This standard is proposed by the professional standard compilation committee for the construction of the main pipeline in the mountainous area and unified. The unit of the standard is: Fuping Oil Machine Factory. The drafter of the standard is Guan Fuxian Jiang Fanggu Mengyao. This standard was issued on December 31, 1987: 1 Scope
