Elbows are key fittings in pipeline systems used to change the direction of fluid flow and are widely applied in construction, industrial, and other fields. The following outlines their core applications and features:
Core Functions
Direction Change: Enables turns at angles of 90°, 45°, 180°, etc., preventing pipe wall deformation and increased fluid resistance caused by sharp bends.
Anti-Clogging Design: The elbow ball-passing process, involving the insertion of two spheres, effectively prevents pipe blockage and is suitable for flood control and cleaning systems.
Common Types
By Angle: 90°, 45°, 180° elbows.
By Connection Method: Female-threaded elbows, male-threaded elbows, flange elbows, etc.
By Material: Wear-resistant ceramic elbows are suited for high-wear environments such as power and metallurgy industries.
Selection Points
Bending Radius: Small-radius elbows (small R value) are suitable for space-constrained situations but increase energy consumption; large-radius elbows (large R value) are suitable for long-distance transport, reducing resistance.
Sealing: Female-threaded elbows enhance compression resistance through optimized structure, preventing leaks.
Installation and Maintenance
Surface Treatment: Shot blasting to remove rust and painting with anti-corrosion coating are required; packaging in wooden crates is necessary for shipment or transport.
Welding Process: End bevel design ensures welding quality and must be consistent with pipe material steel grades.
