1. Definition and Basic Structure
An ABS 45° Short Turn Street Elbow is a specialized pipe fitting designed to change the direction of a pipeline by 45 degrees. Unlike conventional elbows, a street elbow features male threads on one end and female threads on the other . This unique design eliminates the need for additional couplings, making it ideal for tight spaces where compactness is critical. The term "street" likely originates from its historical use in utility connections (e.g., water, sewage) between main lines and street-side infrastructure .
2. Technical Specifications
Material: Acrylonitrile Butadiene Styrene (ABS), known for its high impact resistance, chemical stability, and lightweight properties.
Temperature Range: Typically -40°F to +180°F (-40°C to 82°C), suitable for both low and high-temperature environments.
Pressure Rating: Generally designed for gravity flow systems rather than high-pressure applications.
Sizes: Commonly available in 3-inch diameters (e.g., Model 1WJA7) but also in variants like 1.5-inch, 2-inch, and 4-inch.
Connection Type: Hub x Spigot (spigot end inserts into the hub end), ensuring secure solvent-welded joints.
3. Key Applications
Plumbing and Drainage: Widely used in sewage and water systems due to ABS’s corrosion resistance and smooth interior flow characteristics.
Industrial Systems: Employed in chemical processing, water treatment, and food industries where chemical inertness is critical.
Cooling and HVAC: Pre-insulated ABS systems (e.g., COOL-FIT brands) leverage its low thermal conductivity.
Electrical Conduits: Some ABS elbows (e.g., PC/ABS blends) are used in cable raceways for their flame-retardant properties.
4. Advantages of ABS Material
Durability: High impact strength even at low temperatures.
Chemical Resistance: Withstands acids, alkalis, and salts (though not aromatic hydrocarbons).
Smooth Flow: Reduced friction losses due to smooth inner walls.
Environmental Safety: Free from heavy metals, compliant with NSF/ANSI 14 and WRAS standards for potable water.
5. Installation and Design Considerations
Jointing Method: Solvent cement welding for leak-free connections.
Compact Design: Short-turn variants save space compared to long-radius elbows.
Color: Typically black or natural (ivory), with yellow used for specialized raceway.
