12 Inch Slip On Flange (300 mm) – Product Description

A 12 Inch Slip On Flange (300 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 used for its ease of installation, strong structural performance, and cost efficiency, making it suitable for low to medium pressure applications in large-scale industrial piping systems.

Manufactured in compliance with ASME B16.5 and ASTM standards, this flange offers excellent strength, dimensional accuracy, and long service life. The 12 inch (300 mm) size is ideal for applications requiring high flow capacity and enhanced mechanical stability, such as oil & gas, petrochemical plants, and power generation facilities.

Slip On Flanges are preferred where quick installation, alignment flexibility, and reduced fabrication costs are essential for project efficiency.

Key Features

  • Easy installation with precise alignment
  • Double fillet welding for strong, leak-proof joints
  • Cost-effective compared to weld neck flanges
  • Smooth bore for efficient fluid flow
  • Suitable for low to moderate pressure applications
