What is Boiler Quality Plate?
Plate can usually be defined as any sheet metal thicker than 6mm which is used in applications where durability is more important than saving weight. Boiler quality plate comes under the umbrella of steel alloys, manufactured for use in pressure vessels and pipelines.
Boilers and pressure vessels are usually created by welding a number of curved steel plates together to create a spherical or cylindrical component. As it is formed into one of these shapes, the component is able endure the extreme strain placed on them by the pressurized fluids and liquidized gases held at cryogenic temperatures. Because of this, weldability is one of the most important attributes of boiler quality plates. There is a large range of boiler quality plate grades which can be used for both onshore and offshore activities.
Important Attributes of Boiler Quality Plate
Tensile toughness is a critical element of boiler quality plate and is important for determining the material’s resistance and indicating its ductility and brittleness. It is necessary to know this as pressure vessels are regularly subjected to extreme temperatures and these temperatures can significantly impact tensile toughness.
Resistance to corrosion is also an important requirement of boiler quality plate and the level of resistance necessary is affected by its target area of application. The chemical composition of the steel grade has a direct impact on performance and can be altered to create exact resistances to many different substances.
Boiler quality plates should also have excellent creep resistant properties, meaning they can be used in extremely high temperatures. this is achieved by hot or cold forming and molding to desired shapes.
Applications of Boiler Quality Plate
Boiler quality plates are largely designed for use in welded pressure vessels toughness is of critical importance. Grades of boiler quality plate span a range of tensile strengths from 430N/mm, making them extremely versatile.
Boiler quality plate is used in a range of applications such as cryogenic transportation where biological specimens must be transported at ultralow temperatures. As boiler quality plate is corrosion-resistant it is also well suited to chemical containment where the integrity of the container must not be risked. This is not limited to toxic products, non-toxic liquids such as oils and milks are stored in these vessels.
Boiler quality plate is also used in the power generation industry for heating water to produce steam and in a number of large buildings for the supply of both hot water and heating.
