Lap Joint Flanges – Manufacturer & Supplier in India
What are Lap Joint Flanges?
Lap Joint Flanges are a type of pipe flange designed for use with stub-end fittings. These flanges are not directly welded to the pipe; instead, they are used in conjunction with a stub end, allowing easy alignment and quick dismantling. This feature makes them ideal for applications where frequent inspection, maintenance, and cleaning are required.
These flanges are commonly used in low-pressure applications, especially in chemical processing, oil & gas, power generation, and water treatment industries.
Key Features of Lap Joint Flanges
Easy Installation & Removal – The rotating feature allows easy bolt hole alignment.
Cost-Effective – Suitable for non-critical applications, reducing material costs.
Corrosion Resistance – Available in stainless steel, carbon steel, and alloy steel for enhanced durability.
Flexibility – Works well with stub ends for better alignment and adaptability.
Ideal for Piping Systems – Used in pipelines requiring frequent maintenance.
