Heat Using Equipment & Material

Manufacturing Inspection

Type Item Name Scope
Type Pressure Vessel Type 1 The value of maximum allowable working pressure (MPa) multiplied by internal volume (㎥) exceeds 0.004, and vessel falls under any of the following.
  • Equipment that heats a solid or liquid by receiving steam or other heat transfer media or by generating steam, where the pressure in the vessel exceeds atmospheric pressure.
  • A vessel that generates steam through a chemical reaction in the vessel, where the pressure in the vessel exceeds atmospheric pressure.
  • A vessel that heats a liquid or generates steam to separate the components of the liquid in the vessel, where the pressure in the vessel exceeds atmospheric pressure.
  • A vessel in which the temperature of the liquid exceeds its boiling point at atmospheric pressure.
Type 2 Maximum allowable working pressure of gas in the vessel exceeds 0.2MPa, and vessel falls under any of the following.
  • Internal volume is 0.04㎥ or more
  • Internal diameter of the shell is 200mm or more (more than 300mm for a steam header) and the length is 1,000mm or more.

Scope of pressure vessels: Enforcement Rule of the Energy Use Rationalization Act [Attached Table 1] / Equipment subject to inspection: Article 31-6 of the same Rule (Article 39 (1) and Article 39-2 (1) of the Act) [Attached Table 3-3]
