B16.47 Series A Class 900 Weld Neck Flanges are generally used in high pressure applications, where hot or cold temperatures exist. These steel ANSI / ASME B16.47 Series A weld neck flanges are circumferentially welded into the system at its neck which means that the integrity of the butt welded area can be easily examined by radiography. These B16.47 Class 900 weld neck flanges reduce the turbulence and erosion inside the pipeline because the bores of both pipe and flange match. This also reduces high stress concentration at the base of the hub of the Series A Class 900 weld neck pipe flange. Such weld neck are favoured in critical applications. The inside diameter of a Class 900 weld neck flange is machined to match the inside diameter of the pipe. Tesco Steel & Engineering manufacture a wide range of high quality B16.47 Series A Class 900 Weld Neck Flanges in India. We offer these flanges in ASME/ANSI/DIN standards.

Advantages of using ANSI / ASME B16.47 Series A Class 900 Weldneck Flanges

Weldneck flanges offer several advantages over other types of flanges, such as slip-on flanges. Here are some of the benefits of using weldneck flanges:

Superior Strength
Weldneck flanges have a long tapered hub that provides additional strength to the connection between the pipe and the flange. The welding process creates a permanent and durable bond that can withstand high pressure and extreme temperatures.

Versatility in Accommodating Different Pipe Sizes
Weldneck flanges are available in various sizes, making them suitable for use with pipes of different diameters. The flanges can also be used with pipes of different materials, such as stainless steel, carbon steel, and alloy steel.

Secure and Leak-Free Connection
The welding process creates a strong and leak-free connection between the pipe and the flange. This ensures that the piping system is safe and efficient, reducing the risk of leaks and other safety hazards.

Easy to Install and Maintain
Weldneck flanges are relatively easy to install, and the welding process can be completed quickly. The flanges are also easy to maintain, requiring only periodic inspection and maintenance to ensure that they are in good working condition.

Applications of ANSI / ASME B16.47 Series A Class 900 Weldneck Flange

Weldneck flanges are used in various industrial piping applications, including:

Oil and Gas Industry
Weldneck flanges are commonly used in oil and gas piping systems, where they are used to transport crude oil, natural gas, and other petroleum products.

Chemical Processing Industry
Weldneck flanges are used in chemical processing plants to transport various chemicals and materials.

Water Treatment Industry
Weldneck flanges are used in water treatment plants to transport water and other fluids.

Power Generation Industry
Weldneck flanges are used in power generation plants to transport steam, gas, and other fluids.
