Alternative Name
Lap Joint Flange 1/2" Class 150 ASTM A105 ASME B16.5, Loose Flange, Backing Flange, Lap Joint Flange, Carbon Steel Flange, Flange for Stub End, Steel Pipe Flange
Information
The 1/2" Lap Joint Flange Class 150 manufactured from ASTM A105 carbon steel is designed for use with stub ends in piping systems built according to ASME B16.5. Lap Joint flanges are commonly used in installations that require frequent maintenance, inspection, or cleaning, allowing easy disassembly and reassembly of piping systems.
The loose flange rotates freely around the pipe, making it easier to align bolt holes during installation. Since the flange does not come into direct contact with the process medium, it can often be manufactured from carbon steel while the stub end is made from a corrosion-resistant material, providing a cost-effective solution.
Material
ASTM A105 is a forged carbon steel widely used for flanges, fittings, and pressure piping components. It offers excellent mechanical strength, good machinability, and excellent weldability, making it suitable for ambient and elevated-temperature pressure service.
Advantages
- Free rotation for easy bolt-hole alignment
- Used with stub ends
- Cost-effective solution for corrosion-resistant piping
- Reusable in systems exposed to erosion or corrosion
- Excellent weldability
- High mechanical strength
- Manufactured according to ASME B16.5
- Supplied with a 3.1 material certificate
Applications
Industrial piping systems, chemical plants, petrochemical industry, process installations, food processing, pharmaceutical industry, maintenance-intensive systems, and pressure pipelines.
We also offer Lap Joint flanges and steel flange rings in many other sizes. If you have any questions, please contact us. Call +48 63 261 42 02 or email biuro@polberis.pl.
