T/ZJASE 013-2022 Road transport of hazardous goods in liquid form using tank vehicles with metal pressure-relieved tank bodies: Periodic inspection rules

Scope

Scope: This document specifies the basic requirements for regular inspections of metal atmospheric pressure tanks (hereinafter referred to as "tanks") for road transport of liquid dangerous goods, the implementation of inspections, the handling of defect issues, and inspection conclusions, etc. This document applies to metal atmospheric pressure tanks manufactured in accordance with GB 18564.1, and does not apply to non-metallic materials, vacuum-insulated tank structures, or tanks used for military equipment with special requirements. Main technical content: (1) Clearly defining the requirements for regular inspection items, criteria, and methods, to promote the implementation of mandatory standards and support the implementation of government management systems. The 2006 and 2019 versions of GB 18564.1 "Road Transport of Liquid Dangerous Goods in Tank Vehicles - Part 1: Technical Requirements for Metal Atmospheric Pressure Tanks" only set out the project requirements for regular inspections, but did not address the inspection methods, which affected the guidance of mandatory rules on regular inspections. In 2021, the Ministry of Transport and other four departments jointly launched a special project to regulate tank trucks. The tank truck management work plan stipulated the criteria for high-risk situations, but the current standard still lacks clear provisions on inspection methods, which to some extent hindered the promotion and implementation of tank truck management work. The formulation of this standard refines and clarifies the items for regular inspections, provides inspection methods for corresponding items, and connects with the inspection basis provided by the four departments' tank truck management plan. It provides specific guidance for tank body inspection institutions to carry out their business and promotes the implementation of mandatory standards and government management requirements. (2) Standardizing the inspection workflow and enhancing t
