Tirupati Enterprises is a trusted manufacturer, exporter, and supplier of Weld Neck Flanges and Stainless Steel Flanges (Grades 304, 304L, 316, 316L), available in a variety of materials, finishes, and sizes in both metric and inch standards. Our Weld Neck Flanges are manufactured using different materials, including:
These flanges conform to Slip-On specifications and are widely supplied across India and Asia.
Weld Neck Flanges are designed for high-pressure applications and are connected by welding the pipe to the flange neck. This unique design distributes stress from the flange to the pipe, minimizing stress concentration at the base of the hub.
These flanges are ideal for applications that involve high pressure and extreme temperature variations, making them suitable for steam pipelines, oil and gas industries, and chemical processing plants.
The inside diameter of a Weld Neck Flange is precisely machined to match the inside diameter of the pipe, ensuring a smooth and efficient flow of fluid or gas through the system.
