A lapped joint flange is a type of flange connection used in piping systems to join two pipes or pipes to fittings, valves, or other equipment. It is also known as a “Van Stone” or “stub-end” flange. Lapped joint flanges are typically used in applications where frequent disassembly and reassembly of the piping system is required. To meet our customers’ diverse requirements, Alloyed Sustainables offers a range of ANSI/ASME B16.5 Lapped Joint Flanges, available in various material grades, sizes, and specifications.

Key Features of Lapped Joint Flanges:

• Overlap Design: Lapped joint flanges have a design where the stub end overlaps the backing flange, allowing for easy alignment during assembly.
• Alignment Ease: The overlapping design simplifies alignment, making it useful when precise alignment is difficult.
• Bolted Connection: These flanges are connected using bolts that pass through holes in the backing flange and attach to adjacent equipment, holding the joint together.
• Stub End Component: The stub end, welded to the pipe, serves as the interface, slightly larger than the backing flange.
• Backing Flange: This standard flange supports the joint, featuring bolt holes and a raised face for connection.
• Gasket Seal: A gasket between stub end and backing flange ensures a leak-free seal during assembly.

Application across Industries:

• Chemical Industry: Lapped joint flanges are used in chemical processing for connecting pipes, valves, and equipment, where frequent maintenance and modifications are needed.
• Water Treatment: These flanges are employed in water treatment facilities for connecting pipes and fittings, especially when dealing with non-metallic materials or corrosive fluids.
• Oil and Gas: Lapped joint flanges can be used in certain non-critical parts of oil and gas pipelines where quick disassembly for maintenance is advantageous.
• Wastewater Management: Lapped joint flanges are suitable for wastewater treatment plants, allowing for easy adjustments and repairs in corrosive environments.
• Automotive Industry: They might find use in the automotive sector for certain fluid conveyance systems that need occasional adjustments.

Our dedication to catering to diverse industries is mirrored in our comprehensive range of lapped joint flanges, expertly crafted from a variety of materials and grades to precisely match the evolving needs of our clients and industries.
