Steel Plates for Boilers and Pressure Vessels

Main Uses:

They are mainly used to manufacture boilers and pressure vessels. The steel plates for pressure vessels can be fabricated into devices that will sustain certain pressure, temperature, and medium, so they are required to possess high strength, good toughness, weldability, and surface quality. Many kinds and sizes of products are required to deliver in heat treatment conditions and satisfy ultrasonic test requirements. These steels are widely used in various sectors of the national economy, such as reactors, heat exchangers, separators, spherical tanks, oil tanks, LPG tanks, boiler steam drums, and pressure pipes in machinery, petroleum and chemicals, electric power, and metallurgy industries, etc.
