High-pressure steam pipeline
Thread Content
Dear users of Haichuan, does anyone know how the pressures in high-pressure steam pipes are classified?
Low pressure below 1.3 MPa, medium pressure between 1.3 and 3.9 MPa, and high pressure above 3.9 MPa. My humble opinion
I found on the internet that for industrial pipeline construction, the regulations in the quota specify: low pressure (0 MPa < P ≤ 1.6 MPa)； Medium pressure (1.6 MPa < P ≤ 10 MPa) ； High pressure (10 MPa < P ≤ 42 MPa) ； High pressure is defined as a steam pipeline with P≥9MPa and an operating temperature of ≥500°C; which standard specifies this requirement exactly?
It depends on what industry you’re in – is it thermal power generation? In thermal power generation, the steam pressure level is much higher, especially in power plants that use supercritical technology and similar methods. In small power plants owned by some factories, the waste steam generated outside of power generation is used for other heat exchange equipment or other purposes, and its quality is relatively low.
Low pressure (0MPa＜P≤1.6MPa)； Medium pressure (1.6 MPa < P ≤ 10 MPa) ； High pressure (10 MPa < P ≤ 42 MPa) ； Steam pipes are considered high-pressure when P≥9MPa and the operating temperature is ≥500°C
Take a look at what high-pressure steam is, and learn about it*.
Low pressure, medium temperature and medium pressure, medium temperature and high pressure, high temperature and high pressure, critical, supercritical, ultra-supercritical.
