Pressure piping components type test regulation (TSG D7002-2023) is a newly revised version issued by the China State Administration for Market Regulation (SAMR) on July 12, 2023.
Importance of pressure piping components in China’s industrialization
With the rapid development of China’s economy and the acceleration of industrialization, pressure piping and its component are increasingly being applied in various industries.
As one of the important means to ensure the safe operation of special equipment, the quality and technical level of pressure piping components has received more and more attention. Therefore, the release of the new version of the “Pressure Piping Components Type Test Regulation (TSG D7002)” (hereinafter referred to as the “Type Test Rules”) has important significance for improving the technical level and product quality of China’s pressure piping component manufacturing industry.
Expanded scope and updated provisions
It is understood that the new version of the “Type Test Rules” clarifies the range of type test products for pressure piping components based on the original version. This includes various types of pressure piping fittings, elbows, flanges, and other components. At the same time, the rules have also made updated provisions for type test procedures, supervision, and management requirements, as well as type test items, contents, and methods of pressure piping component products. The release of these provisions will help standardize and strengthen the quality management and supervision of China’s pressure piping component manufacturing industry and improve the overall quality and technical level of products.
Ensuring quality and compliance
Specifically, the new “Type Test Rules” version has more stringent and detailed provisions for type test procedures. Manufacturers are required to carry out material selection, process control, and other work per standard requirements to ensure that products meet relevant technical requirements and standard specifications. In addition, the rules have made detailed provisions for type test items, contents, and methods. For example, in a type test, it is necessary to test and evaluate the product’s dimensions, wall thickness, surface roughness, etc., to ensure that the product quality meets the relevant standards and requirements. At the same time, the rules also require manufacturers to establish a sound type of test management and supervision mechanism to strengthen the monitoring and control of product quality.
Strengthened supervision and management
In addition to the provisions for type test procedures, the new version of the “Type Test Rules” has also updated and improved supervision and management requirements. It requires special equipment safety supervision agencies at all levels to strengthen supervision and inspection of pressure piping component manufacturing enterprises and establish sound enterprise quality files and databases. In addition, the rules also require manufacturers to establish a sound after-sales service system to handle user feedback issues and complaints timely.
Universal application
The release of these provisions will help improve product quality and service levels and enhance market competitiveness. It is worth mentioning that this “Type Test Rules” applies to pressure piping component manufacturing enterprises in China and overseas manufacturers. This means that whether they are domestic or foreign enterprises, as long as they are pressure piping component manufacturers, they must conduct type tests under this updated rule.
