ASME B16.5 Class 1500 Slip On Flanges are designed for high-pressure applications where easy installation and alignment are crucial. Commonly referred to as SORF Flanges #1500 (Slip On Raised Face) and SOFF Flanges #1500 (Slip On Flat Face), these flanges are widely used in piping systems where welding on both sides is preferred for added strength. Tesco Steel & Engineering manufactures high-performance slip on flanges that meet ASME B16.5 specifications and are trusted for their precision, durability, and ease of assembly in critical industrial settings.
At Tesco Steel & Engineering, our ultra-modern Bhayandar factory is equipped with advanced CNC machines, automated welding stations, and rigorous in-house testing procedures. This enables us to deliver superior-quality Class 1500 slip on flanges with consistent dimensions, smooth finishes, and excellent resistance to high pressure and corrosive media. Our team of skilled engineers ensures that each flange undergoes stringent quality checks before it leaves the facility, making our products suitable for demanding environments like oil refineries, chemical plants, marine systems, and power infrastructure.
We proudly export our ASME B16.5 Class 1500 SORF and SOFF flanges to a wide range of global markets, including the USA, Germany, France, Italy, Saudi Arabia, UAE, and Kuwait. Our flanges are relied upon across various industries such as oil & gas, petrochemical, power generation, and offshore engineering. Tesco Steel & Engineering has built a solid reputation for delivering high-grade flanges that conform to international standards, offering clients both quality assurance and excellent value with every shipment.
