Detailed Information

Prashaant Steel & Alloys is a maker of 300 LB Flange Dimensions of exceptional quality. The 300 LB Flange Dimensions that we manufacture are highly common due to their superior quality. 300 LB Flange Dimensions have the standards of the correct specifications to be used in surface drilling and production. These flanges have a long history, and many of these have been discontinued or replaced with a newer version. We are one of the top API 6A Flanges Manufacturers in India who produce high-quality API 6A Weld Neck Flange and other types of flanges with current configurations.

ANSI 300 Lb Flange is manufactured by using high quality material and this is usually designed to close, cover the end of the piping system. It includes various dimensions and specifications and based on that this product is introduced in the market. ASME 300 LB Flange is basically used in industries like chemical, industrial and many other applications. The packaging of this is done by using wooden boxes and other bubble wraps. Due to this it will be safely dispatched to the desired location.

300 class flange can handle more pressure compared to rest of the classes of flanges. The metal used in this has the ability to sustain the pressure and also many other factors are involved in this. Well, depending upon the pipe size, the number of bolts and holes are decided. Class 300 Flange is thus available in stock and they have the excellent corrosion resistance capacity.

Flange is the metal which is used to connect two pipes, valves and pumps in the piping system. It is used for various applications like plumbing system and in other industrial areas. 300 LB flange dimensions specifies the dimensions of the flange and accordingly it is manufactured. It has unique diameter, diameter of holes and nominal size. There are various classes of this flange; hence 300 LB flange is able to handle more pressure as compared to class 150 flange.
