How to judge the quality of boiler steel plate?

Boiler steel plate is a kind of steel designated for the manufacture of pressure vessels and pipelines. There are various specifications and grades of boiler steel plates, which are suitable for onshore and offshore installations, natural gas extraction, petroleum refining, chemical isolation, low-temperature transportation, petrochemical and natural gas production, etc.

Pressure vessels and boilers are usually manufactured by welding a plurality of bent steel plates together to form cylindrical or SPHErical parts. This geometry allows the components to withstand the strains imposed by pressurized fluids and liquefied gases at low temperatures. Therefore, weldability is one of the most important properties of boiler steel plates.

The tensile toughness of the boiler steel plate is essential for determining the mechanical strain resistance of the material, but it also shows the brittleness and ductility. Pressure vessels usually continue to withstand extreme temperatures, which may greatly change the tensile toughness of the steel used in their manufacture.

The design of the boiler steel plate has excellent toughness and can cope with environmental pressure and external pressure. They have passed the highest level of notch toughness testing to ensure that the material is neither too hard nor too brittle, and provides durable strength and ductility under harsh conditions.
