Product Description
Our Quick Delivery SS 304/316L Slip-On Flange (RF/RTJ) is precision forged from high-quality stainless steel in compliance with ASTM A312 standards. Designed for reliable and leak-proof piping connections, this flange is ideal for applications requiring corrosion resistance, durability, and ease of installation.
Featuring both Raised Face (RF) and Ring Type Joint (RTJ) sealing surfaces, the slip-on flange allows quick, welding-free installation by sliding the pipe into the flange bore and securing it with welds on the outside and inside of the connection. This design ensures a tight, secure joint suitable for low to moderate pressure piping systems.
Manufactured to meet rigorous industrial standards, this slip-on flange suits a broad range of applications, including chemical processing, water treatment, oil & gas pipelines, and general industrial use. Its corrosion resistance and robustness make it a dependable choice in harsh environments.
