Hot Rolled Coils
/Boiler plate used to manufacture mainly refers to the superheater , the main steam pipe and boiler room fire heating surface hot rolled plate material ,/Rebar
/ the main materials are of high quality structural steel and low alloy heat-resistant steel , commonly used in boilers have open-hearth steel smelting carbon killed steel or mild steel smelting furnace , carbon Wc within the range of 0.16% -0.26 % . Since the boiler plate in medium temperature (350 º C or less ) high pressure job , in addition to withstand high pressures , but also by the impact of fatigue loads and water and gas corrosion performance requirements boiler steel is mainly good welding and cold performance, certain high temperature strength and alkali resistance , corrosion resistance and oxidation .Medium Heavy Plate
Boiler and pressure vessel steel plate and perform major criteria: (1 ) The main steel boiler plate has : 20g, 16Mng, 15CrMoVg, 19Mng, 22Mng (2) pressure vessel steel plate mainly have : 20R, 16MnR, 15MnNbR, 15MnVNR (3) standard : GB713-1997, GB6654-1996.
Boiler and pressure vessel plate main purposes : widely used in petroleum, chemical, power plants , boilers and other industries for the production of reactors, heat exchangers, separators, tank , gas tank, gas cans , nuclear reactor pressure vessel , boiler drum , liquefied petroleum gas cylinders, high pressure water station , water wheels and other equipment and components volute .
