Class 300 Flange

Class 300 Flange

We are leading 300 Lb Weld Neck Flange Manufacturer in India, Check Dimensions of ASME B16.5 Class 300 Flanges

Flanges are designed in different pressure classes that help in determining their load-bearing capacity. A Class 300 Flange is a versatile grade that is designed to hold pressures up to 570psi at 600 degrees F. As the temperature increases within these flanges, their load-carrying capacity gradually starts decreasing. The ANSI B16.5 Class 300 Flanges are designed in a cast or forged material grades. These flanges are designed in NPS sizes of 1/2 to 24 NPS. The robust ANSI B16.47 Series A Class 300 Flanges are stronger, heavier, and thicker in comparison to standard series B grade. The grade A flanges also tend to be more expensive than grade B flange types.

Check ANSI 300 Socket Weld Flange and ASME CL300 Orifice Flanges torque specs, Pressure Class and Weight

The ASME CL300 Slip On Flange is a popular cost-effective flange in the industry. These flanges are slid on the pipe surface and aligned to the fixture, making use of one or more fillet welds. ANSI B16.5 Class 300 Blind flanges are used to curtail or terminate the flow of fluids and gases in the system. These flanges are generally bolted to the flange allowing room for inspection and maintenance of the flange. An ANSI 300 Socket Weld Flange is a high-strength flange that is seen in high-pressure systems where there are small pipe fixtures. These flanges are an attachment that is fitted in place using a single filled weld. The ANSI B16.5 class 300 Lap Joint Flanges are made up of a two-component assembly with a stub end and a ring-type sealing that allows the flange to swivel around the pipes. These flanges have a long service life as they don’t constantly come in contact with the fluid or gases inside the fixtures. Our esteemed workers make use of the best raw materials and latest technology to produce the best in class products in the industry.
