In October 2014, the Special Equipment Safety Supervision Bureau (hereinafter referred to as "the SESSB") of the former General Administration of Quality Supervision, Inspection and Quarantine of the People's Republic of China (hereinafter referred to as “the former AQSIQ”) issued the revision assignment of Pressure pipe installation supervision inspection regulation (hereinafter referred to as the Installation supervision inspection regulation). In April 2015, China Special Equipment Inspection and Research Institute organized relevant experts to set up a drafting group and held the first meeting in Guangzhou to discuss the principles, key contents and main problems to be solved in the revision of the Installation supervision inspection regulation, and to make specific arrangement for the revision work and formulate the revision work schedule. In November 2015, the drafting group held the second meeting in Beijing to discuss and revise the draft, and an exposure draft was formulated. In April 2016, the SESSB issued ZHIJIANTEHAN [2016] No.13 to solicit opinions from basic-level departments, organizations concerned, experts and the public. In August 2016, the drafting group held the third meeting in Beijing to study and discuss the opinions received, and the draft for review is formulated through revision. In May 2017, the SESSB submitted the draft for review to the Special Equipment Safety and Energy Saving Technical Committee of the former AQSIQ for review, and then the draft for approval is formulated by the drafting group through revision based on the review opinions. With the transformation of government functions and the advancement of administrative licensing reform, the drafting group added the relevant contents on pressure pipe unit manufacture supervision inspection as required by the SESSB in the Regulation so as to coordinate with the Announcement of the State Administration for Market Regulation on matters related to administrative licensing of special equipment [2019] No.3 and the Regulation for production and filling licensing of special equipment (TSG 07-2019). In April 2019, the fourth meeting was held to discuss the relevant contents on pressure pipe unit manufacture supervision inspection added in the Regulation, and the Pressure pipe supervision inspection regulation (TSG D7006-2020) (hereinafter referred to as the Supervision inspection regulation) was formulated as a draft for approval after revision. On May 16, 2020, the Regulation was approved and issued by the State Administration for Market Regulation. The basic principles of this revision are as follows: 1. the current Rule on safety, quality supervision and inspection for pressure piping installation (GUOZHIJIANGUO [2002], No.83) is revised as the Safety technical regulations for special equipment in order to coordinate with Special equipment safety law of the People's Republic of China and Special equipment catalog; 2. the relevant contents are adjusted and improved to clarify the nature and positioning of pressure pipe unit manufacture supervision inspection, and pressure pipe installation, alteration and major repair supervision inspection according to the implementation of Pressure pipe unit manufacture supervision inspection regulation (submerged-arc welding steel pipe and polyethylene pipe) (TSG D7001-2005) and Rule on safety, quality supervision and inspection for pressure piping installation (GUOZHIJIANGUO [2002], No.83) as well as the industry development; 3. the Supervision inspection regulation is revised based on the requirements for safety management of special equipment, in line with the concept of serving enterprise development, and in combination with the reform of safety supervision management of special equipment in China in recent years and the advanced international safety management experience; 4. the obligations and responsibilities of all organizations, institutions and personnel concerned in the supervision inspection, as well as the supervision inspection procedures, contents and requirements are standardized; 5. the pertinence, effectiveness and scientificity of supervision inspection items are highlighted, and the special supervision inspection requirements for pressure pipe units, long-distance pipes, utility pipes and industrial pipes are proposed.
