Expander flanges provide reliable, long-lasting connections for high-pressure oil and gas pipelines, handling variable flow rates and ensuring safe transitions.
These flanges seamlessly accommodate piping system changes, helping prevent leaks in chemical processing plants and ensuring smooth transitions for fluid and gas flow.
In thermal and nuclear plants, expander flanges ensure reliable high-pressure connections between pipes of different sizes, optimizing heat exchange systems.
Expander flanges are ideal for refinery systems, where fluid dynamics and pipe transitions require both strength and flexibility for long-term performance.
Used for water distribution networks, they manage pressure transitions and help maintain the structural integrity of the piping system.
Expander flanges ensure smooth and safe transitions for slurry pipes, reducing the risk of corrosion and wear in mining and processing operations.
Reducing the cost of maintenance and downtime is crucial in manufacturing, where each delay can lead to significant losses. Our Expander Flanges (Weld Neck Type) feature a robust, one-piece construction that not only offers high-strength performance but also reduces the need for additional fittings and maintenance.
Whether you are managing pressure systems in industrial plants or ensuring safe water delivery, these flanges provide the reliability and durability required, ultimately lowering long-term operational costs.

The Expander Flange is available in pressure ratings from Class 150 to Class 2500 (PN10 to PN420), depending on the outlet flange size. This wide range ensures compatibility with various pipeline systems across industries. It offers the flexibility to meet both low and high-pressure demands.
Yes, our Expander Flanges are designed to withstand harsh environments. We offer a clad construction, combining a carbon steel body with stainless steel or Alloy 625 liners, which significantly improves corrosion resistance. This makes them suitable for chemical processing, oil, and gas applications.
The nominal size of the inlet ranges from ½” to 12″ (DN15 to DN300), while the outlet can be up to 24″ (DN600), with a maximum 4:1 expansion ratio. Todetermine the correct size, match the outlet flange size to the dimensions of your piping system. Our team canassist in selecting the right configuration based on your requirements.
Our Expander Flanges come with surface finishes of 125-250 μin RA for Raised Face (RF) and 63-125 μin RA for Ring-Type Joint (RTJ) on the outlet side. The bore is polished to 32 μin Ra, ensuring smooth operation and sealing performance. These finishes meet industry standards for both aesthetic and functional purposes.
Yes, our Expander Flanges can be customized to meet specific application needs, such as different material grades or coating options. We offer flexibility in material selection, including Carbon Steel, Stainless Steel, and Alloy Steel. Additionally, we provide internal coatings like FBE for corrosion protection and Xylan for slurry service, ensuring the flange suits your unique operational requirements.
