ASME B16.5 Class 150 slip on flanges are ideal for low-pressure pipelines where easy installation and alignment are critical. These flanges are designed to slide over the pipe and are then welded both inside and outside to provide enhanced strength and leak prevention. At Tesco Steel & Engineering, we manufacture Class 150 slip on flanges using high-grade raw materials and strict dimensional accuracy to ensure optimal performance in a wide range of piping systems.
As a trusted and experienced manufacturer, Tesco Steel & Engineering delivers slip on flanges that meet global quality benchmarks. Our ASME B16.5 Class 150 slip on flanges are widely used in water supply systems, HVAC projects, and general industrial piping where moderate pressure handling is sufficient. Each flange we produce is tested for strength, finish, and durability, ensuring that our clients receive a product that offers both value and long-term reliability.
Our slip on flanges are exported to numerous countries including the United States, Germany, Italy, UAE, Saudi Arabia, and Qatar, serving industries such as petrochemical, energy, shipbuilding, and construction. With a reputation for consistent product quality and on-time delivery, Tesco Steel & Engineering has become a preferred supplier for clients across both Western and Middle Eastern markets. Whether you need standard sizes or customized solutions, our flanges are engineered to meet the highest expectations.
