By Bending Angle
Standard Elbows: Fixed angle elbows such as 90°, 45°, 180°, etc.
Custom Angle Elbows: Non-standard angles customized according to requirements (e.g., 30°, 60°).
By Bending Radius
Short Radius Elbows (SR): Bending radius ≈ 1 times the pipe diameter, space-saving but with higher fluid resistance.
Long Radius Elbows (LR): Bending radius ≈ 1.5 times the pipe diameter, lower fluid resistance, suitable for high pressure or high flow velocity scenarios.
By Manufacturing Process
Stamping Elbows: Formed by stamping with molds, suitable for thin-walled pipes.
Welded Elbows: Multiple pipe sections welded into an elbow, low cost but sealing must be strictly inspected.
Hot Push Elbows: Heated pipe material formed by a pushing machine, with uniform wall thickness, suitable for large diameter pipes.
Cold Bending Elbows: Bent at room temperature using a bending machine, suitable for small diameter pipes, low cost but prone to springback.
By Material
Metal Pipes: Carbon steel, stainless steel, alloy steel, etc., resistant to high temperature and high pressure, suitable for industrial pipelines.
Plastic Pipes: PVC, PE, PP, etc., corrosion-resistant, suitable for water supply, drainage, or chemical pipelines.
Composite Material Pipes: Such as fiberglass pipes, combining the advantages of metal and plastic, suitable for special environments.
