Stainless Steel Weld Neck Flanges Manufacturers and Exporters

MANUFACTURER/EXPORTER OF HIGH QUALITY WELD NECK FORGED FLANGES

Satin Steels Solutions specializes in manufacturing high-quality weld neck flanges that meet ASME, ANSI, and DIN standards in India. We offer immediate delivery programs for standard sizes of carbon steel and stainless steel weld neck flanges. Weld neck pipe flanges are attached to pipes by welding the pipe to the neck of the flange, which transfers stress from the weld neck to the pipe, reducing high stress concentration at the base of the flange hub. These flanges are typically used in high-pressure applications and in environments with extreme temperatures. The inside diameter of a weld neck pipe flange is precisely machined to match the pipe’s inside diameter.

CARBON, ALLOY, STAINLESS STEEL WELD NECK FLANGES

We manufacture weld neck pipe flanges at our facility, supplying them to companies across various industries, including shipbuilding, power generation, petrochemical plants, oil refineries, wastewater treatment plants, paper mills, pharmaceutical plants, and turnkey projects, among others. Our products are widely exported to countries and regions such as the United States, Europe, Russia, Turkey, Malaysia, the UAE, Saudi Arabia, Iran, Brazil, Chile, Mexico, South Africa, Jordan, Tunisia, Vietnam, Indonesia, Thailand, Singapore, Colombia, and Sri Lanka.

What is WNRF Flanges ?

A Weld Neck Raised Face (WNRF) Flange, commonly referred to as a Weld Neck Flange, is a type of flange intended for welding onto a pipe. It features a long, tapered neck that gradually transitions to match the pipe’s diameter. This design makes the WNRF Flange particularly suitable for high-pressure and high-temperature applications.

Materials Used in Manufacturing:

WNRF Flanges can be made from various materials, such as carbon steel, stainless steel, and alloy steel. The selection of material depends on the specific requirements of the project, including the application’s temperature and pressure conditions.

Advantages of Using WNRF Flanges

Using WNRF Flanges in your project offers several advantages. Their design is ideal for high-pressure and high-temperature applications, ensuring safety and reliability. The welding process used to attach the flange to the pipe creates a strong and permanent connection. Furthermore, WNRF Flanges are versatile and suitable for various applications, including oil and gas, chemical processing, and power generation.

WNRF Flange Dimensions and Standards: WNRF Flanges are available in various sizes and dimensions, making it essential to select the correct size for your project. They are manufactured according to several standards, including ASME/ANSI, API, and DIN. Our team can assist you in choosing the appropriate size and standard for your needs.

Proper installation of WNRF Flanges is crucial for the safety and reliability of your project. Our team can provide guidance on correct installation procedures to ensure your project’s success.

These flanges are bored to match the inside diameter of the fitting or mating pipe, preventing flow restriction, turbulence, and reducing erosion at the joints. They offer excellent distribution via a tapered hub and can be easily radiographed for flaw detection. Additionally, these flanges can be easily welded to fittings or pipes with a V weld or single full penetration weld.
