Loose Lap Joint Flange

Home / Industrial Flanges

ASME/ANSI B16.5 & B16.47 Lap Joint Flange Manufacturer, Supplier & Exporter

Lap Joint Flanges are specially designed to be used with a stub end, providing a practical and flexible piping connection solution. Unlike conventional flanges, Lap Joint Flanges are not directly welded to the pipe, allowing the flange to rotate freely around the pipe. This feature simplifies bolt hole alignment during installation and makes assembly, disassembly, and maintenance much easier. Due to their versatile design, Lap Joint Flanges are widely used in industries such as chemical processing, water treatment, food processing, pharmaceuticals, and petrochemical plants where frequent system inspection or modifications may be required

One of the major advantages of Lap Joint Flanges is their ability to reduce installation time and maintenance costs. Since the flange can be reused and easily removed, it is an economical choice for low-pressure and non-critical service applications. These flanges are manufactured in a variety of materials including Stainless Steel, Carbon Steel, Alloy Steel, Duplex Steel, and other special alloys to provide excellent corrosion resistance, strength, and durability across different operating conditions.

Arrow Piping Solutions is a trusted manufacturer, supplier, and exporter of premium-quality Lap Joint Flanges manufactured in compliance with ASME/ANSI B16.5 and B16.47 standards. We offer a comprehensive range of Lap Joint Flanges in various sizes, pressure ratings, and material grades to meet diverse industrial requirements. Our products are manufactured using advanced technology and undergo strict quality inspections to ensure dimensional accuracy, superior performance, and long service life. With competitive pricing, prompt delivery, and customer-focused service, Arrow Piping Solutions delivers reliable flange solutions for industrial applications worldwide.
