ASME B16.5 Class 600 Slip On Flanges are widely used in high-pressure piping systems where strong, reliable, and easy-to-install connections are required. These flanges are commonly known as SORF #600 (Slip On Raised Face), SOFF #600 (Slip On Flat Face), and SO Flanges #600. Designed to be slipped over the pipe and then welded on both the inside and outside, they ensure a leak-proof joint and enhanced strength. At Tesco Steel & Engineering, we manufacture premium-quality Class 600 slip on flanges that conform to ASME B16.5 standards, delivering consistent performance in critical industries.
Our state-of-the-art Mumbai factory is equipped with advanced CNC machinery, automated fabrication systems, and strict inspection protocols, allowing us to produce slip on flanges of exceptional quality and precision.
