Type of Sub-products

Slip On Flange

Slip On Flange

These flanges slide over the pipe and are then welded, offering easy alignment and cost effectiveness. Commonly used in low pressure, non critical piping across water treatment and HVAC systems.

Weld Neck Flange

Weld Neck Flange

Designed for high stress applications, this flange features a tapered hub for reinforcement. Ideal for oil & gas, chemical processing, and high pressure steam systems.


Frequently Asked Questions

What materials are commonly used in manufacturing flanges?

Flanges are manufactured using a range of materials such as stainless steel, carbon steel, alloy steel, duplex steel, and copper-nickel alloys. The material choice depends on factors like operating pressure, temperature, and fluid type. For corrosive or high-temperature environments, stainless steel and high-alloy flanges offer enhanced durability and performance.

Which standards govern the production of industrial flanges?

Flanges are typically manufactured according to international standards such as ASME B16.5, EN 1092-1, DIN, and ASTM. These standards define dimensions, pressure classes, materials, and tolerances to ensure compatibility and safety. Adherence to these norms is essential for reliable performance in industrial piping systems worldwide.

What are the different types of flanges used in piping systems?

Common flange types include weld neck, slip-on, blind, socket weld, threaded, and lap joint flanges. Each type serves a specific function, such as sealing pipe ends, allowing maintenance access, or connecting equipment. The choice of flange depends on pressure rating, installation requirements, and flow characteristics.
