class 300 flanges

ASME B16.5 300# Forged Flange is used in power generation, petrochemical, construction, gas, and petroleum industries. Furthermore, these 300lb Series Series B Flanges are also used in metallurgy, shipbuilding, heavy oil refineries, and nuclear power equipment. To denote the pressure rating of Stainless Steel Class 300# Flange the terms lb, class, and # are used interchangeably. In fact, the 300 class has no relation to the pressure rating 300 PSI. they are completely different and cannot be interchanged. Carbon Steel Class 300 Flange are usually in high demand due to their durability, and corrosion resistance properties. 

Class 300 Welding Neck Flanges are said to have good fabricability and ductility. The pressure rating of ANSI B16.5 Class 300 Forged Flanges depends upon the condition in which it is heat-treated and the pressure class. 300 Lb Flange supplied by us is manufactured as per international grades and standards. We use the best quality material to ensure that these Class 300 Pipe Flanges retain the best possible properties.




What Pressure Is A 300 Flange Rated For?


At a temperature range of 600 degrees F 6 Inch Class 300 Flange has a pressure rating of 570 psi.


What Is Class 300 Flange?


Class of flange can be defined as the temperature and pressure rating specified for a particular group of flanges. Class 300 Flanges are a type of flanges that are constructed with more metal. Hence as per Class 300 Lb Flanges manufacturer In India they can withstand more pressure than the other class. The size range of Class 300 RF Flange varies between ½ inch to 48 inches. They are available in forged, form, threaded, or plate type. The dimension supporting material for raised face flange includes ring joint, gasket, and 28300 lb flange dimension. 


How Thick Is A 300 Flange?


As per the ANSI B16.47 Series, A Class 300 Flanges chart a flange with the size of I inch will generally have an outer diameter of 4.88 and a minimum thickness of 0.62.
