SY/T5236-2000
This standard is based on the SY5236-91 "Sucker rod hook" industry standard, retains the main technical requirements applicable to the sucker rod hook, adds two types of products, stipulates the measurement method of the maximum residual deformation of the lifting ring, and standardizes the editing format.
This standard is proposed and managed by the National Technical Committee for Standardization of Petroleum Drilling Equipment and Tools. This standard was drafted by: Yumen Petroleum Administration Bureau Machinery Factory. The main drafters of this standard are Qiang Shengyu, Yang Yonghong and Liu Lin. This standard was first issued in July 1991, and this is the first revision. 1 Scope
