Application
The highperformance boiler and pressure steel plate are widely used in many variety of boiler or pressure vessel steel equipment, including oil tank, hydraulic fluid tream,water, petrochemical and nuclear fields, reactor, heat exchange, absorbers. According to the different pressure requirement,we supply the ASTM,ASME,EN ,PED standards and other customized request.
Advantages
1. Most of EN and ASME standard can be satisfied .
2. For the indicated project, special technical agreement will be signed for satisfying customerized steel character.
3. The fundamental property of steels for pressure vessels is their ability to withstand high pressure at different temperatures.They have good weld ability, as well as excellent toughness, and are suitable for normalization annealing and stress-relief annealing .
4. Steel with a guaranteed high yield strength,ultramate tensile strength can satisfy with the required standard and dimensions.
