Steel Plates for Boilers and Pressure Vessels
Steel Plates for Boilers and Pressure Vessels
Main Application
They are mainly used in the manufacture of boilers and pressure vessels. The steel plates for boilers and pressure vessels can be fabricated into device that are subject to certain pressure, temperature and medium, so they are required to possess high strength, good toughness, weldability and surface quality. Many varieties and specifications of the products are required to delivery in heat treatment condition and satisfy ultrasonic testing requirements. This type of steel is widely used in various fields of the national economy, such as reactor, heat exchanger, separator, spherical tank, oil tank, LPG tank ,boiler steam drum and pressure pipes in machinery, petroleum and chemicals, electric power and metallurgy industries, etc.
Delivery Conditions
Hot rolled, controlled rolled, normalized, normalized+tempered, quenched +tempered,ect.
