About Double Flange Bend

To control the flow of liquids as well as the pressure of fluids, gas, and sewages, our double flange bend is attached to pipes. It is designed for bending in a double curvature as a result of the connected element's restraint. The flange will curve in one direction when there is no restraint force. A classic recessed mount extrusion, the double flange bend has flanged edges that conceal the recessed edge for a sleek and contemporary installation. When uniformly smooth lighting is required, blend to reduce potential LED dotting with a little more regression.

Robust Design for Pipeline Integrity

Double Flange Bends are built to enhance pipeline durability and integrity. With a round section shape and internal cement mortar lining, these bends offer superior mechanical properties and corrosion protection, vital for long-lasting water and sewage flow systems. Their rigid structure guarantees reliable performance under varying operational pressures and thermal conditions.

High-Performance Coating & Testing

These bends receive fusion bonded epoxy or bitumen coatings for heightened corrosion resistance. Every unit undergoes factory leak-proof testing at 1.5 times the rated pressure, ensuring operational reliability. With close manufacturing tolerances of 2 mm and precise drilling standards, you receive a product engineered for safety, efficiency, and minimal maintenance.

FAQs of Double Flange Bend:

Q: How is the Double Flange Bend installed in pipelines?

A: Installation is achieved by bolting the drilled flanged ends to matching pipeline flanges, using gasket seals for a robust, leak-proof connection. Skilled personnel should ensure flange alignment and correct torque as per IS 1538 or BS EN 1092-2 standards.

Q: What fluids can be transported using this flange bend?

A: It is suitable for water, sewage, and various non-corrosive liquids, making it ideal for municipal, industrial, and irrigation piping systems. The internal cement mortar lining and external coatings provide additional fluid compatibility and protection.

Q: When is this product recommended for use?

A: Double Flange Bends are recommended for pipeline sections requiring directional changes with high mechanical strength and enhanced corrosion resistance, particularly in water and sewage distribution infrastructure or industrial fluid transport.

Q: Where can these flange bends be utilized?

A: They are widely used in municipal water supply, sewage treatment plants, industrial fluid piping, and irrigation projects throughout India and in international export markets.

Q: What is the process for manufacturing these bends?

A: Manufactured using centrifugal casting, the bends are precision-machined and internally lined with cement mortar. Flanged ends are drilled per IS/BS/EN standards, and the surface is treated with fusion bonded epoxy or bitumen coating before undergoing stringent leak-proof testing.

Q: How does the product benefit pipeline systems?

A: It delivers high durability, excellent corrosion protection, and leak resistance. The design minimizes maintenance needs, ensures system reliability under pressure, and accommodates standard bend radii to suit various layout requirements.
