Long Weld Neck Flanges
Riddhi Siddhi Metal Impex is a reliable Long Weld Neck Flanges Manufacturer which provides high performance flanges which can be used in high pressure and high-temperature environments. These flanges are fabricated using stainless steel, carbon steel, and special alloys with a long neck which enhances the joint between the flange and the pipe, stress concentration contrary to stress concentrations and the carrying capacity. They are designed to suit very sensitive sectors like oil and gas, power generation, refineries, and shipbuilding. These flanges are made in smooth and serrated finishes, and may be used in seamless systems of piping where adjustment and strength are necessary. The flanges are also tested through ultrasonic, pressure and PMI tests to ensure reliability in operation and long life.
This is a range that is tailored to accommodate various industrial projects and challenging piping specifications. Face types such as RTJ or raised face can be customized to individual applications with custom sizes and neck lengths, pressure ratings and face types. We also provide Socket Weld Flanges in the mid paragraph of the paragraph, which are suitable in the project where a secure and accurate connection is needed. These flanges are available on a reputable B2B Platform, and hence they are readily accessible to large scale operations. The timely delivery of the product and efficient logistics guarantees continuity of the working process, which is why this collection could be a reliable solution to the industrial clients in the global market.

Frequently Asked Questions
What is a Long Weld Neck Flange?
A Long Weld Neck (LWN) flange is a type of flange with an extended neck that resembles a pipe, allowing it to connect seamlessly with pipelines. Unlike regular weld neck flanges, the elongated neck is designed for applications involving high pressure, extreme temperatures, and critical stress conditions. The extended neck provides additional structural support, making it ideal for connecting vessels, valves, or equipment in industries like oil and gas, petrochemicals, and power generation.
How is a Long Weld Neck Flange different from a standard Weld Neck Flange?
The primary difference lies in the neck length. Long Weld Neck flanges have a longer neck, which provides additional support and enables a seamless transition with the connected pipe, especially in high-stress situations. This unique design reduces stress concentration at the weld area, enhancing the flange’s resistance to bending, temperature fluctuations, and mechanical loads. Standard weld neck flanges are generally used for lower-stress applications.
What materials are used to manufacture Long Weld Neck Flanges?
Long Weld Neck flanges are made from various materials depending on the service conditions. Common materials include carbon steel, stainless steel, alloy steel, duplex, and super duplex stainless steels, and even nickel-based alloys for highly corrosive environments. Material selection depends on factors like operating temperature, pressure, and corrosion resistance requirements of the application, with higher-grade materials chosen for extreme conditions.
