Is a pressure-reducing and temperature-reducing device a pressure pipeline component?

Is a pressure and temperature reducer considered a pressure pipeline component? What qualifications are required from suppliers?； I don’t know where to find the basis for this?
Pressure reducing and temperature reducing devices are generally manufactured by boiler auxiliary equipment manufacturers. Their main working components are valves; the expansion section is, in theory, considered part of pressure pipelines. However, the pressure reducing and temperature reducing devices I have dealt with did not comply with the regulations regarding pressure pipelines or pressure vessels – they simply had ordinary certification documents
It belongs to safety accessories! Scope of regulation!
The category of \"component assembly devices\" in the new Catalog refers to devices that are formed by welding pressure pipeline components such as pipes, valves, fittings, and flanges together to achieve a specific function. Currently, manufacturing licenses are only issued for wellhead equipment, production trees, throttle and kill manifolds, as well as gas pressure regulating devices and temperature and pressure reducing devices.
A certificate of conformity and a TS certificate are required
Yes. Last year, Document No. 515 issued by the General Administration of Quality Supervision required that boiler temperature and pressure reduction devices must have a manufacturing inspection certificate.
The cooling and pressure reduction system used in the original company back then didn’t come with any certificates; it only had a regular certificate of conformity issued by the design company
It seems that many sea travelers are not very familiar with these regulations. Let me explain: The qualification required for manufacturing temperature and pressure reduction devices is the \"Manufacturing License for Pressure Pipeline Components\", which falls under the category of \"Licenses for Special Equipment\". As shown below:
