We are a fast growing organization, engaged in manufacturing, supply and export of welding neck flanges, industrial weld neck flanges and forged flanges.

Our weld neck flanges are drilled with the wall thickness of flange having the same dimensions of pipe. Flanges for heavier pipes have smaller bore, while flanges of lighter pipes have larger bore.

These weld neck flanges, industrial weld neck flanges, forged flanges are normally used for high-pressure, cold or hot temperature.

A flange is used to mechanically connect two pipes together. It can also be used to mechanically connect a pipe to a tee, valve, choke or any other piece of equipment. Flanges are available in round, square, and rectangular shapes. In some cases, flanges are usually in the shape of a ring or a plate to form a rim at the end of a pipe when fastened to the pipe. This is an example of closet flange. A flange can also be a plate for covering or closing the end of a pipe. This is a blind flange. Thus, flanges are considered to be projecting or internal components which are used to support mechanical parts. They are like rims which are used to strengthen the mechanical part or they are a means of attaching that part to another part or surface.

We offer high quality DIN flanges that conform to the standard specifications of DIN

• Deutsches Institut for Normung (German Institute for Standardization). These din standard flanges can be availed in different material specifications including carbon steel, stainless steel and alloy steel. Available at the most reasonable prices, our steel DIN flanges can work efficiently under high temperature and pressure.

Applications of pipe flanges:

Pipe flanges are widely used in pipe fittings of various industrial, commercial and residential applications. Pipe flanges can be customized to suit your application with various machining details. These pipe flanges have been used extensively in:

• Hydraulic control systems for turbine generators
• High pressure ground support missile systems
• Nuclear and conventional power plant applications etc.

Designs of flanges:

A wide variety of flange designs are available. They are available in various shapes and sizes. Some of the popular designs are as follows:

• Butt weld
• Socket weld
• Captive
• Split
• Square
• Round
• Rectangle etc.

Custom shapes and sizes are also manufactured by numerous manufacturers. Various pipe flanges include machining details such as gasket surfaces, facing details, non-standard drilling, bevel and radius edges, o-ring grooves and raised or recessed faces. Some typical designs on flanges faces are shown below.
