Double Flanged Duckfoot Bend 90 Degree Description

The double flanged duckfoot bend provides a 90 degree change of direction in piping systems. This elbow features a duckfoot, or gooseneck, style bend for optimized flow control around the tight radius.

The double flanged ends allow easy integration into your existing pipeline setup. Flanges are available in slip-on or weld neck styles. Common flange standards include ASME/ANSI B16.5 and B16.47.

Constructed from quality materials like carbon steel, stainless steel, alloy steel, and more. Material choice depends on your pressure, temperature, and corrosion resistance needs. Sizes range from 1/2" to 48" in diameter.

Custom options available including non-standard materials and dimensions. Double disk flanges improve strength and minimize leaks. The duckfoot design reduces turbulence and erosion compared to standard 90 degree elbows.

Ideal for applications like steam lines, combustible fluids, HVAC, water lines, chemical processing, hydrocarbons, and anywhere requiring a 90 degree turn with smooth flow. Made to order based on your exact specifications.

• Reduced Pressure Loss - The gradual directional change enables lower pressure loss than standard elbow joints. This improves efficiency.

• Leak Protection - The double flanges provide a robust sealing surface and strengthen the joint integrity to minimize leakage.

• Easy Installation - The flanged ends allow simple connection to existing pipelines without the need for welding or threading.

• Space Saving - Tight 90 degree turn requires less space than long radius elbows or pipe offsets.

• Versatile Use - Suitable for a wide range of applications and industries like steam, water, chemical, HVAC, petrochemical, etc.

• Durable Materials - Constructed from carbon steel, stainless steel, alloy steels to handle high pressure and temperature applications.

• Custom Options - Made to order with non-standard materials, sizes, and dimensions available to meet specific requirements.

• Quality Manufacturing - Fabricated under tight tolerances and high standards for long service life and reliability.

Double Flanged Duckfoot Bend 90 Degree applications ：

• Steam Lines - The smooth flow helps reduce erosion in steam lines with high velocity fluids and particulates. Useful where steam direction needs to change.

• HVAC Systems - Provides tight bend radius while minimizing turbulence and pressure loss in HVAC ducting and piping systems.

• Water Lines - Smooth water flow around the bend prevents excessive erosion and corrosion in water lines.

• Chemical Processing - Suitable for corrosive chemicals like acids thanks to stainless steel and alloy material options.

• Hydrocarbon Processing - Allows smooth flow of oils, gases and slurries in refineries and petrochemical plants.

• Combustion Systems - Enables tight 90 degree turn for gases, exhaust fumes, and flue fluids with reduced turbulence.

• Plumbing Systems - Compact size and leak-proof joints are useful for residential and commercial plumbing applications.

• Fire Protection Systems - Reliable 90 degree connection for sprinkler systems to deliver pressurized water.
