Product Description

Stainless steel forged flanges are vital for connecting pipes, valves, pumps, and other equipment in piping systems. Renowned for their strength, corrosion resistance, and durability, these flanges also allow easy access for cleaning, inspection, and modification.
Two flanges are secured with bolts and a seal to ensure a leak-proof connection. While various flange standards exist, our products adhere to strict regulations, guaranteeing both functionality and interchangeability.
Notably, forged flanges offer superior strength compared to drawn flanges, as they are crafted from a single piece of raw material without welded joints.
