Expander Flanges
M Metal Tubes India Pvt Ltd manufactures high-quality Expander Flanges for connecting smaller pipes to larger ones without using additional reducers. These flanges provide a compact, leak-proof solution for bore enlargement at the connection point. Built from stainless steel, duplex, and high-performance alloys, our expander flanges comply with ASME standards and ensure efficient flow in high-pressure and corrosive environments.
M Metal Tubes India Pvt Ltd is a renowned manufacturer and exporter of Expander Flanges engineered for seamless and space-saving pipe size transitions. Backed by 40+ years of industry expertise and ISO-certified production, we offer expander flanges that meet ASME, EN, and JIS standards for reliable performance in high-pressure, high-temperature, and corrosive applications.
What Are Expander Flanges?
Expander Flanges are specialty flanges used to increase the bore size of a pipeline at the flange connection point. They feature a tapered internal bore that gradually expands, allowing a smaller pipe to connect directly to a larger pipe or equipment without requiring an additional reducer fitting. This reduces installation time, saves space, and ensures smooth fluid flow with minimal turbulence.
