Product Overview
This precision 180 elbow provides complete flow reversal in industrial piping systems. The durable 180 degree pipe elbow design features both long radius (LR) and short radius (SR) configurations to accommodate different layout requirements. Manufactured from corrosion-resistant WP304 stainless steel to ASME B16.9 standards, this robust 180 elbow ensures excellent performance in demanding applications. The smooth interior surface of this 180 degree pipe elbow minimizes pressure drop and prevents turbulence during flow direction change. Ideal for chemical processing, oil and gas, and power generation applications, this high-quality 180 elbow guarantees leak-proof performance where complete flow reversal and system integrity are essential requirements. The precision-formed 180 degree pipe elbow maintains perfect alignment for easy installation in demanding service conditions.
Key Features
- Precision 180° Directional Change: Specifically engineered for 180-degree directional flow reversal, making it ideal for compact heating coils, heat exchangers, and U-bend piping configurations.
- Optimal Long Radius (LR) Design: The Long Radius geometry minimizes internal turbulence and pressure drop, ensuring smooth fluid transition and reduced wear on the pipe walls.
- High-Grade WP304 Stainless Steel: Fabricated from premium ASTM A403 WP304 stainless steel, providing excellent resistance to oxidation and reliable performance in diverse industrial environments.
- Durable Butt Weld Construction: Features a robust butt weld design that creates a permanent, leak-proof, and high-strength joint capable of withstanding significant system pressure.
- Compliance with ASME B16.9: Fully compliant with international ASME B16.9 standards, ensuring exact dimensional consistency for easy integration into global piping networks.
- Certified Quality Standards: Produced in a facility certified under ISO 9001:2015 and GB/T19001-2016. Full documentation, including Material Test Reports (MTRS), is available to ensure complete traceability.
