The common working pressures of steam boilers, classified by application and scenario, have a very clear range, directly providing you with the most practical range:

Low-pressure boiler (the most commonly used
Working pressure: 0.4 MPa to 1.25 MPa
It is widely used in: food, pharmaceuticals, washing, dyeing and printing, small-scale chemical industry, heating, and disinfection

Medium-pressure boiler
Working pressure: 1.6 MPa to 2.5 MPa
It is widely used in: medium-sized factories, papermaking, rubber, and some chemical processes

Medium and high-pressure boiler
Working pressure: 3.8 MPa to 5.3 MPa
It is mostly used for: small power stations and large-scale industrial centralized steam supply

Factories, canteens, hospitals and hotels: 0.7 MPa or 1.0 MPa are the most common
Slightly higher requirements: 1.25MPa, 1.6MPa
Very few civilian or small-scale industrial applications exceed 2.5 MPa
If you tell me the purpose (such as food sterilization, garment factories, heating, etc.), we can directly tell you the most suitable pressure.
