Leak-proof connections, ideal for high-pressure applications.
Ecostain Rainbow is a well-known threaded flange manufacturer, supplier and exporter in India. Our stock includes a diverse range of standard sizes, both in carbon steel and stainless steel forms, and we have quick delivery times. The threaded flanges are made in compliance with international quality standards such as ANSI/ASME B16.5, ANSI/ASME B16.47 Series A and Series B, and API standards. Ecostain Rainbow Engineering Export is a master in the manufacture, supply, and export of threaded flanges by utilizing different materials like carbon steel, stainless steel, alloy steel, and exotic materials including Duplex, Super Duplex, Nickel Alloys, Hastelloy, and Inconel. We have a global presence, serving customers across six continents and around 110 countries, and are recognized for their top-quality and dependable products.
Threaded flanges have threads on the inner bore that match the threads on the pipe, allowing for a screw-in connection. They are typically used in low-pressure applications where welding is not feasible or desired. Threaded flanges are commonly found in plumbing systems, small-diameter piping, and low-pressure applications such as water supply lines.
All Flanges with standard sizes and materials are readily available in stock for immediate delivery. "Looking for large diameter Flanges ? Contact us today for Customized Flanges.
As a threaded flange manufacturer, we make sure our threaded flanges adhere to the following -
Plumbing Systems: They are widely used in plumbing installations for connecting pipes, valves, fittings, and fixtures in residential, commercial, and industrial buildings.
Fire Protection Systems: Threaded Flanges are employed in fire sprinkler systems, hydrant installations, and firefighting equipment for connecting pipes and fittings.
HVAC Systems: They are used in heating, ventilation, and air conditioning (HVAC) systems for ductwork connections, air handling units, and fan installations.
Small-Bore Piping Systems: Threaded Flanges are ideal for small-diameter piping systems, low-pressure applications, and non-critical services where a removable connection is required.
Process Industries: They find applications in process industries such as food and beverage, pharmaceuticals, and pulp and paper for connecting piping systems, equipment, and instrumentation.
Removable Connection: Threaded Flanges provide a removable connection that allows for easy assembly and disassembly of piping systems without the need for welding.
Convenience: They offer convenience in installations where frequent disassembly or maintenance is required, allowing for quick and easy adjustments or repairs.
Versatility: Threaded Flanges can be used with a wide range of pipe materials, sizes, and schedules, providing flexibility in piping system design.
Cost-Effective: They are typically more cost-effective compared to welded flanges, making them suitable for budget-conscious projects or applications.
We conduct a series of testing procedures to ensure the quality, reliability, and performance of our Flanges.
These tests are conducted at various stages of manufacturing, from raw material inspection to the final product testing.
