What regulations and standards have been issued for the safety and management of pressure pipelines

Answer] :d process of starting the heating up, the high-temperature pipeline needs to be hot-tightened on the pipe flange connecting bolts, and the low-temperature pipeline needs to be cold-tightened.

Legal analysis: In order to standardize the supervision and inspection of the manufacture of pressure pipeline components (supervision and inspection, hereinafter referred to as supervision and inspection) and the supervision and inspection of the installation, transformation and major repair of pressure pipelines (installation, transformation and major repair, hereinafter referred to as construction), these rules are formulated in accordance with the "Special Equipment Safety Law of the People's Republic of China" and the "Regulations on the Safety Supervision of Special Equipment".

On August 31, 2009, the General Administration of Quality Supervision, Inspection and Quarantine of the People's Republic of China approved and promulgated the Rules for the Administration of Registration of the Use of Pressure Pipelines, which came into force on December 1, 2009. On July 13, 2003, the "Rules for the Administration of Registration of the Use of Pressure Pipelines (Trial)" issued by the General Administration of Quality Supervision, Inspection and Quarantine of the People's Republic of China was repealed at the same time. These rules are aimed at the technical processing encountered in the comprehensive inspection of the use registration process and the problems encountered in the promotion of the inspection work, and at the same time simplify the requirements for the use of registration.

Legal basis: "Rules for the Administration of Registration of the Use of Pressure Pipelines".

Article 1 In order to standardize the registration management of the use of pressure pipelines, these rules are formulated in accordance with the "Regulations on the Safety Supervision of Special Equipment" and the "Decision on the Establishment of Administrative Licenses for Administrative Examination and Approval Items that Really Need to Be Retained".

Article 2 These rules apply to the use and registration management of pressure pipelines within the scope of the "Regulations on Safety Supervision of Special Equipment".

Article 3 The pressure pipeline use unit, property rights unit, and individual owner (hereinafter referred to as the user unit) shall handle the pipeline use registration in accordance with the provisions of these rules and obtain the "Special Equipment Use Registration Certificate".

Article 4 The General Administration of Quality Supervision, Inspection and Quarantine of the People's Republic of China is responsible for handling the registration of the use of long-distance pipelines that cross provinces, autonomous regions and municipalities directly under the Central Government, the provincial-level quality and technical supervision departments are responsible for handling the registration of the use of long-distance pipelines that do not cross provinces, autonomous regions and municipalities directly under the Central Government within their respective administrative regions, and the quality and technical supervision departments of cities divided into districts (hereinafter referred to as registration authorities) are responsible for handling the registration of the use of public pipelines, industrial pipelines and power pipelines within their respective administrative areas.

Answer]: Huaixin lacks a, b, and c

This question examines the basic knowledge of special equipment. In order to meet the needs of safety supervision and management, pressure pipelines are divided into three categories: long-distance pipelines (GA), public pipelines (GB), and lead industrial pipelines (GC).
