Product Description

The ANSI B16.5 Lap Joint Flange is a type of flange designed according to the American National Standards Institute (ANSI) B16.5 specifications. Here’s a detailed product description:

1. Design: The lap joint flange features a unique design with two main components: a flat, circular disc (the “stub end”) and a ring or hub (the “lap joint”). The stub end is typically welded to the pipe or fitting, while the lap joint is free to rotate around the stub end. This design allows for easy alignment during assembly.
2. Materials: ANSI B16.5 lap joint flanges are available in a wide range of materials to suit various applications and operating conditions. Common materials include carbon steel, stainless steel, alloy steel, and other specialty alloys.
3. Sizes: These flanges are manufactured in a range of sizes to accommodate different pipe diameters and pressure ratings. They are available in nominal sizes ranging from 1/2 inch to 24 inches or larger, with pressure ratings ranging from 150 lbs to 2500 lbs.
4. Facings: The flange face can be raised face (RF), flat face (FF), or ring type joint (RTJ), depending on the application requirements and sealing preferences.
5. Standards: ANSI B16.5 lap joint flanges conform to the dimensional standards set forth by ANSI, ensuring compatibility and interchangeability with other ANSI B16.5-compliant components.
6. Applications: Lap joint flanges are commonly used in piping systems where frequent dismantling and reassembly are required, such as in systems handling corrosive or abrasive fluids, or in applications with thermal expansion considerations.
7. Assembly: During assembly, the lap joint flange is placed over the stub end, and the joint is sealed using a gasket. Bolts are then inserted through the holes in the lap joint and tightened, pressing the flange faces together and compressing the gasket to create a tight seal.
8. Versatility: Lap joint flanges offer versatility in piping design and installation, allowing for easy alignment adjustments and disassembly without disturbing the entire piping system.

Overall, ANSI B16.5 lap joint flanges are a reliable and versatile solution for joining piping systems in a wide range of industrial applications.
