The boiler plate a boilerplate

Is mainly refers to used to make superheater tube boiler, the main steam heating room with fire and hot rolling steel plate material, the main material is high quality structural steel and low alloy steel heat, the commonly used boiler steel smelting steel mill have the low carbon steel smelting furnace of calm or low carbon steel, carbon content in Wc, 0.16%-0.26% range. Due to the boiler plate in temperature (350 and ordm; C below) work under high pressure, in addition to withstand higher pressure outside, still affected, fatigue load and water and corrosion of steel of boiler performance requirements of the main is to have good welding and the cold bending property, certain high temperature strength and alkali resistance, resistance to oxidation and corrosion.

Boiler and pressure vessel with board basically GangHao and standards

(1) boiler plate GangHao mainly has: 20 g, 16 Mng, 15 CrMoVg, 19 Mng, 22 Mng

(2) pressure vessel with GangHao board basically have: 20 R, 16 MnR, 15 MnNbR, 15 MnVNR

(3) standards: GB713-1997, GB6654-1996

Boiler and pressure vessel with the main purpose of the board

Widely used in petroleum, chemical industry, power plant, boiler, etc, and used to make the reactor, heat exchanger, separator, spherical tank, YouQiGuan, liquid tank, nuclear reactor island, boiler drum, liquefied petroleum gas cylinders, high pressure water pipes, turbine hydropower station equipment and components such as spiral case

 

Steel Pressure vessel of the English name is Pressure vessel steel plate that is used for manufacturing Pressure vessel shell of carbon steel and low alloy steel plates. It includes carbon steel, alloy steel, carbon manganese steel, micro with low-alloy steel and low temperature with steel. Work in 20 °C-the average temperature to 500 °C, 560 °C individual can reach. Among them is mainly refers to 16 MnR steel (16 mn let low alloy steel, a steel models), is used to make ASME standard pressure vessel.

1) the highest working pressure (Pw) (note 1) than to be equal to 0.1 Mpa (do not contain liquid static pressure, similarly hereinafter);

(2) in diameter (the royal section that its biggest form size) than to be equal to 0.15 m, and volume (V) (note 2) than to be equal to 0.25 m3;

(3) loading medium for gas liquefied gas or the highest working temperature is higher than standard boiling pointliquid.

The use of pressure vessel is very extensive. It is in the petroleum chemical industry, energy industry, scientific research and military industry and so on the economy in each department plays an important role in the equipment. Pressure vessel is general by cylinder, sealing head, flange, seal components, opening and take over, bearing and so on six big part containers ontology. In addition, still with security devices, meter and complete the different production processes in a role. Pressure vessel, pressure and medium due to seal and other reasons, easy to explosion, fire burning endanger personnel, equipment and the security of the property and environmental pollution accidents. At present, in every country in the world as its important prison for products, specialized agency designated by the state, in accordance with the regulations and standards and technical supervision and inspection of the implementation of inspection
