Lap Joint Flange Gasket Manufacturers in India
Viton Metal And Forging is a leading Lap Joint Flange Gasket manufacturer in India, providing premium sealing solutions for a variety of industrial applications. Lap joint flange gaskets are designed for use with lap joint flanges, which consist of a hub welded to the pipe and a loose ring flange that rotates freely. These gaskets sit between the hub and the ring flange, ensuring a reliable seal when the flanges are bolted together. Available in materials such as non-asbestos fiber, PTFE, and elastomeric compounds, they offer excellent resistance to different fluids and operating conditions.
As the leading Lap Joint Flange Gasket supplier in India, weensures that these gaskets simplify installation by allowing easy alignment of bolt holes without rotating the pipe itself. Their design makes them ideal for applications requiring frequent disassembly and maintenance, such as large-diameter pipelines and systems exposed to vibration or mechanical stress. we delivers high-quality lap joint flange gaskets that enhance operational efficiency and durability in critical industrial environments.
Type of Sub-products
Full Face Gasket
Full-Face Gaskets for lap joint flanges cover the entire surface area within the bolt circle and feature pre-cut bolt holes. These gaskets provide excellent sealing for low-pressure applications and help align the flange faces evenly. They are commonly used in water systems, HVAC installations, and low-pressure chemical pipelines.
Ring Type Gasket
Ring-Type Gaskets are designed to sit only around the pipe bore and within the raised face area of the flange, providing a focused seal on the pressure-retaining area. They are suitable for higher-pressure systems where minimizing gasket contact area helps increase sealing efficiency. These gaskets are widely used in process industries like petrochemical, oil & gas, and refineries.
Frequently Asked Questions
What is the advantage of using lap joint flanges and gaskets?
They simplify alignment during pipe installation because the loose ring flange can rotate independently of the pipe. This is also helpful for maintenance and disassembly.
Where are lap joint flange gaskets typically used?
In applications where frequent disassembly is needed, alignment is critical, or minimizing stress on the pipe is important, such as large diameter pipelines or systems with vibration.
Are there standard sizes for lap joint flange gaskets?
es, they are generally manufactured to correspond to standard flange dimensions (e.g., ASME B16.9 for lap joint flanges).
