1 Scope This standard specifies the technical requirements, test methods, inspection rules, marking, packaging, storage and transportation of steel vessel with mechanical agitating equipment (hereinafter referred to as “the agitating vessel”). This standard is applicable to the agitating vessels that meet the requirements of GB 150, JB/T 4735 and HG/T 3109. The agitating vessel with mechanical agitating equipment is a steel vessel whose technological operation process is to use agitating liquid as the main medium (accompanied by gas and solid phases) and carries out various physical and chemical processes. Typical combination types of vessels and mechanical agitating equipment include top-in, oblique-in, bottom-in, side-in, etc. It is not applicable to the following agitating equipment: ——agitating vessels heated by flame directly; ——agitating vessels under radiation; ——agitating vessels for fatigue analysis; ——glass-lined agitating vessels; ——agitating vessels that is frequently moved. 2 Normative references The following normative documents contain provisions which, through reference in this text, constitute provisions of this standard. For dated references, subsequent amendments (excluding corrections) to, or revisions, of any of these publications do not apply. However, parties to agreements based on this standard are encouraged to investigate the possibility of applying the most recent editions of the normative documents indicated below.
