SPV355 steel is a kind of Japanese standard steel for medium temperature pressure vessels. The executive technical standard of SPV355 steel is JIS G3115. SPV355 steel is widely used in petroleum, chemical industry, power station, boiler and other industries. SPV355 steel is used to make reactor, A573 grade 70 steel sheet heat exchanger, separator, spherical tank, oil and gas tank, liquefied gas tank, nuclear reactor pressure shell, boiler drum, liquefied petroleum cylinder, high-pressure water pipe of hydropower station, turbine volute and other equipment and components.
Strong pressure resistance of A573 grade 70 steel sheet, boiler steel tube: The wall thickness of boiler steel tube is very important, because the steam pressure is very large, if the wall thickness is very thin, it will be broken by the steam pressure released instantly. The boiler steel tube has good high temperature resistance performance: the steam temperature in the pipeline can reach hundreds of degrees Celsius above. If the high temperature resistance performance is not enough, the boiler steel tube will be melted by the high temperature brought by the steam.
The main raw material of A573 grade 70 steel sheet, hot rolling coil is billet. After heating the billet, the strip made from the coarse and fine rolling mill is cooled to a certain temperature by specific cooling, and then the cooled steel strip is made into rolled steel strip by coiler. But generally, according to the buyer's demand, the manufacturer can further process the cooled steel strip into steel plate or flat coil and other products.
