The JIS B2220 Lap Joint (LJ) flange is a versatile and reusable flange designed for applications requiring frequent assembly, disassembly, or alignment adjustments. It consists of a loose flange that slides over the pipe or fitting and works in conjunction with a stub end or pipe end. This design minimizes wear on the flange itself, making it ideal for systems where corrosion resistance and flexibility are critical.
Material Specifications:
JIS B2220 Lap Joint flanges are available in various materials to meet application-specific requirements:
- Carbon Steel: SS400, S20C
- Stainless Steel: SUS304, SUS316, SUS316L
- Alloy Steel: SCM435
- Duplex Stainless Steel: SUS329J3L
- Other Materials: Copper alloys, aluminum, and titanium for specialized needs.
Material selection depends on operating conditions, such as pressure, temperature, and fluid type.
Key Features:
- Two-Part Design: Loose flange and stub end allow for easy alignment and assembly.
- Reusable: Flange can be reused even if the stub end is replaced, reducing costs.
- Corrosion Resistance: Ideal for systems prone to corrosive fluids when made from stainless steel or alloys.
- Flexible Installation: Enables easy adjustments to bolt holes during assembly.
- Standards Compliance: Manufactured according to JIS B2220 standards for precision and reliability.
Applications:
- Oil & Gas: Piping systems in corrosive environments such as offshore platforms.
- Chemical Processing: Handling aggressive chemicals requiring high corrosion resistance.
- Food & Beverage: Hygienic piping systems for transport of liquids and gases.
- Water Treatment: Flanges in desalination, wastewater treatment, and distribution systems.
- Marine and Offshore: Piping connections in ships and offshore structures.
