Slip On Flanges

Stainless Steel Screwed Flanges, also known as Threaded Flanges, are manufactured in compliance with ANSI B16.5 standards and are widely used in various industrial sectors. These flanges are available in stainless steel, alloy 20, carbon steel, duplex steel, and high nickel alloys, offering a range of material options to suit demanding applications. Commonly used where welding is not feasible, threaded flanges provide a practical solution for high-pressure environments at or near atmospheric temperatures.

Threaded Flanges are ideally suited for applications requiring easy assembly and disassembly without welding. However, they are not suitable for environments involving elevated temperatures, cyclic conditions, or situations where bending stresses may lead to thread leakage. Their design makes them suitable for high-pressure systems where strength, reliability, and ease of maintenance are key considerations. These flanges are used extensively in power plants, chemical processing, and oil and gas pipelines.

These flanges are available in various grades including Monel 400/K500, Inconel, Hastelloy, Super Duplex, and Alloy Steel, ensuring superior performance under corrosive and high-stress conditions. The product is appreciated for its high tensile strength, precise dimensions, durable finish standards, and robust performance. They are engineered to meet the needs of both standard and custom applications, ensuring compatibility and efficiency.

Threaded Flanges are exported to numerous countries worldwide, including Qatar, Kingdom of Bahrain, Saudi Arabia, Indonesia, the United States, Singapore, Malaysia, Turkey, UAE, Russia, Ukraine, South Africa, and Australia. This extensive export network showcases the reliability and global demand for these precision-engineered components.

Specialized in the production of Threaded and Screwed Flanges, manufacturers also offer custom solutions including Inconel Threaded Flanges, BS-4504 Screwed Flanges, and Hastelloy variants, fulfilling the specific needs of clients across multiple industries. These products are manufactured with strict adherence to international standards and quality norms.

Why choose Slip On Flanges??

  • Easy Installation – Simple to align and weld onto pipes.
  • Cost-Effective – More affordable than weld neck flanges
  • Versatile Fit – Ideal for low-pressure, non-critical applications.
  • Less Welding Required – Requires only fillet welds on both sides.
  • Available in Various Sizes & Materials – Suitable for multiple industries.
