18 Inch Slip On Flange (450 mm) – Product Description

An 18 Inch Slip On Flange (450 mm) is a heavy-duty piping component designed to slide over the pipe and be secured with fillet welds on both the internal and external sides. It is widely preferred for its ease of installation, cost efficiency, and dependable sealing performance, making it suitable for low to medium pressure applications in large-scale industrial piping systems.

Manufactured in accordance with ASME B16.5 and ASTM standards, this flange ensures excellent strength, dimensional precision, and long service life. The 18 inch (450 mm) size is commonly used in industries requiring very high flow capacity and structural stability, such as oil & gas, petrochemical plants, water transmission systems, and power generation facilities.

Slip On Flanges are ideal where quick installation, alignment flexibility, and reduced fabrication costs are critical for efficient project execution.
