PED Approved 300 LB Pipe Flange, ANSI B16.5 300# flange Manufacturers in India.
ASME B16.5 class 300 flange belongs to the class 300 of B16.5 standard which covers flanges of ¼ inches to 24 inches in diameter. R.C. Metal Corporation is a leading manufacturer and supplier of the 300 LB Pipe Flanges in various sizes and types. The material grade and the application requirement along with the standards and specifications determine the 300# flange dimensions. There are different wall thicknesses to the flanges and the classes vary accordingly. There are classes from 150 through 1500. The Stainless Steel Flange Class 300 is a medium range class with medium range pressure capacities. The flanges also have pressure numbers to indicate the pressure capacities ranging from PN6 through PN64.
ASME B16.5 Class 300 Flange
Class 300 Forged Flanges is one of the different types such as the threaded flanges and screwed types. The forged ones are made from a single piece of material and they tend to be stronger. Depending on the Class 300 Flange Material the flanges could be heat treated to further harden or strengthen them. The different material types offer different service purposes. The Class 300 Carbon Steel Flanges is used for its high toughness. The application can be seen in high wear and tear applications. There are also different face types to the flanges such as flat face, raised face and ring type joint. The Class 300 Raised Face Flanges has a raised face which allows for maximum connection efficiency by providing extra surface.
There are different types by their functionalities as well. The Class 300 Reducing Flange reduces the diameter of the pipe and reduces the fluid flow inside the pipeline. There are also flanges with grooves in them. These Grooved Flange Class 300 types are used for easy installation with pipes. The grooves support the pipes to be held in place. The ring type joint Class 300 Rtj Flange comes in two halves with two rings which are welded to two ends of different pipes. The pipes are then welded together by welding the rings together as one. Please feel free to contact us for more information on the 300 Lb Class Flange and pricing.
