Product Description

Introduce

Boiler pressure vessel steel sheet is mainly used to manufacture superheater, main steam pipe and boiler fire chamber heating surface used in hot rolled medium thick plate material. Boiler steel plate is one of the very key materials in boiler manufacturing, mainly refers to the hot rolled special carbon steel and low alloy heat resistant steel medium thick steel material used to manufacture boiler shell, pot drum, box end cover, hanger and other important parts.It includes carbon steel, carbon manganese steel, microalloy steel, low alloy high strength steel and low temperature steel. Operating temperature is generally -20ºC to 500ºC, individual up to 560ºC. These are mainly 16MnR steel (16 manganese capacity low alloy steel, a type of steel), which is used in the manufacture of ASME code pressure vessels.

Cutting large steel plates as your requirements to make the surface of the plate bright by miling and grinding, also can make holes and make angle degrees,and can weld by your drawing. For the thickness under 30mm, cutting by laser; For thickness over 30mm, mainly OXY-cut, flame cutting. For the thickness 200mm steel plate, because during the flame cutting, the temperature is very high, so the cutting parts steel plate might be broken at the angle part, then our workers will repair the angles to be good condition.
