Tirupati Enterprises is a recognized manufacturer, exporter, and supplier of Threaded Flanges and Stainless Steel Flanges (Grades 304, 304L, 316, 316L). We offer a wide range of flanges in various grades, materials, and finishes, available in both metric and inch sizes.
Our Threaded Flanges are available in multiple material options, including:
All our Threaded Flanges comply with Slip-On specifications and meet industry standards in India & Asia.
A Threaded Flange is commonly used in low-pressure piping systems because it allows for easy assembly without welding. However, welding can be applied around the joint after assembly for additional reinforcement, though it is not considered a reliable method for increasing strength.
With years of expertise in manufacturing high-precision industrial flanges, Tirupati Enterprises ensures quality, durability, and compliance with international standards. Our Threaded Flanges are designed to offer long-lasting performance, easy installation, and cost-effective solutions for various industries.
