Q245R Material Introduction
Q245R is a commonly used material for steel plates for pressure vessels, which complies with the Chinese national standard GB713 and also meets the requirements of ASME Section VIII for material properties. The material has the following characteristics:
Chemical composition: low carbon, low alloy steel, the main components include C, Mn, Si, etc., to ensure excellent toughness and welding performance.
Mechanical properties:
Yield strength: ≥245 MPa
Tensile strength: 450-600 MPa
Elongation: ≥21%
Introduction of head types
2:1 Ellipsoidal head is a type of head commonly used in the design of pressure vessels, whose shape consists of two curves with different radii and has the following features:
High structural strength
Uniform stress distribution
Wide range of application:commonly used in storage tanks, heat exchangers, desulfurisation towers and other equipment in high pressure and sulfur containing environment.
Introduction to head testing
1. Material testing
2. Non-destructive testing (NDT)
3. Pressure Test
4. NACE HIC/SSC test
