The Stainless Steel Groove 45-Degree Elbow is a high-strength pipe fitting designed for grooved piping systems, providing a reliable, vibration-resistant solution for changing pipe direction in heavy-duty applications. Manufactured from 304 or 316 stainless steel, this elbow features a grooved end (AWWA C606 compliant) that connects to couplings or valves without threading or welding, enabling fast installation and maintenance.
Grooved Connection Advantages:
AWWA C606 grooved ends accept mechanical couplings (e.g., Victaulic-style), allowing installation in minutes with simple wrenches, reducing labor costs by 40% compared to welded systems.
Groove dimensions (depth, width) precision-machined to ±0.1mm tolerance for consistent coupling engagement.
Robust Construction:
Seamless or welded stainless steel body (304 for general use, 316 for corrosive environments), with yield strength ≥250 MPa and impact resistance (Charpy V-notch ≥27 J at 20°C).
45° angle design reduces stress concentration compared to 90° elbows, ideal for high-vibration applications like pumps and compressors.
Flow Optimization:
Smooth internal radius (1.5x pipe diameter) minimizes turbulence and pressure loss, with polished bore (Ra ≤1.6μm) for laminar flow in water, oil, and gas systems.
Groove location away from the bend ensures coupling seals are not affected by pipe deflection, maintaining leak resistance under thermal expansion.
Compliance & Testing:
Meet ASME B16.24, MSS SP-83, and AWWA C606 standards, hydrostatically tested to 1.5x MAWP (up to 300 PSI for 304 stainless steel).
Optional electro-polishing for high-purity systems, reducing surface roughness to Ra ≤0.8μm for pharmaceutical and semiconductor applications.
Perfect for heavy-duty and large-diameter piping:
Water Distribution: Municipal water mains, wastewater treatment plants, and fire protection systems (NFPA 20 compliant), with grooved connections enabling quick expansion of pipe networks.
Industrial Plants: Cooling water circuits, steam lines, and bulk material conveying systems in power plants and refineries, with 316 stainless steel resisting chloride stress corrosion.
Mechanical Systems: Vibration-prone equipment connections (e.g., pumps, generators), with grooved couplings absorbing minor misalignments and reducing stress on the elbow.
Marine & Offshore: Seawater intake systems and deck piping, with 316 stainless steel providing superior resistance to saltwater corrosion and biofouling.
Q: What is the maximum pipe size available?
A: Sizes range from 2" to 48" NPS, with custom sizes available for special projects.
Q: Can grooved elbows be used in above-ground and underground installations?
A: Yes, suitable for both environments; use polyethylene casing for underground protection in corrosive soils.
Q: How to prevent galvanic corrosion with dissimilar metals?
A: Use dielectric couplings when connecting stainless steel elbows to carbon steel pipes, and apply anti-corrosion tape to grooved ends.
Q: What is the recommended torque for coupling bolts?
A: Follow the coupling manufacturer's guidelines, typically 50-70 N·m for 2"-12" elbows to ensure uniform sealing pressure.
