Pipes within the scope of boilers as per GB/T16507

GB/T 16507 is the standard number for the \"Regulations on Safety Technical Inspection of Water Quality for Steam Boilers\". In accordance with Chinese laws and regulations, the design, production, installation, and use of boilers and their safety accessories must comply with a series of **standards and industry regulations. Whether the pipelines within the boiler area require a TS (Special Equipment Production License) depends mainly on the specific parameters of the pipelines and their operating conditions. In China, the boiler itself as well as the pressure pipelines directly connected to it are considered special equipment. In accordance with the Special Equipment Safety Law and the Regulations on the Supervision of Special Equipment Safety, entities that manufacture, install, modify, or maintain such special equipment must obtain the corresponding TS permits. If the pipes within the boiler area are pressure pipes, and parameters such as pressure and temperature fall within the scope of regulation specified in the Provisions on the Supervision and Management of the Manufacture of Pressure Pipeline Components, then these pipes require corresponding TS approvals during their manufacturing process. When purchasing such pipes, the purchasing entity should also ensure that the supplier holds the appropriate TS license. Specifically, for high-pressure pipelines as well as medium and low-pressure pipelines, whether they fall under the scope of TS licensing depends on factors such as the pipeline’s pressure rating, diameter, and type of fluid carried. Therefore, when purchasing pipes as part of the boiler system, it is necessary to thoroughly understand and confirm the specific parameters of those pipes, and determine whether a TS license is required in accordance with relevant regulations such as the Special Equipment Safety Law and the Provisions on the Administration of Special Equipment Production Licenses. As laws and regulations may be updated, and as the specific requirements for pipelines can vary depending on different operating conditions and environments, it is recommended to consult the local authorities responsible for regulating special equipment or professional certification bodies before proceeding with any operations, in order to obtain the most up-to-date guidance and assistance. .
