The Hydraulic Used Pipe Bending Machine is a specialized heavy-duty equipment engineered to produce large-diameter pipe elbows—catering to the core needs of pipe fitting manufacturing in industries like oil & gas, petrochemicals, power engineering, and municipal infrastructure. It leverages hydraulic drive technology for stable, high-torque bending, enabling it to handle thick-walled, large-diameter pipes that standard pipe benders cannot process.
What defines this machine is its balance of processing capacity and bending precision: it covers pipe diameters from 325mm to 1066mm (the largest elbow diameter) and wall thicknesses of 10-50mm, while strictly controlling quality indicators like pipe wall thinning rate (<10%) and elbow ellipticity (<10%). This ensures the bent elbows meet industry standards for structural strength, pressure resistance, and assembly compatibility, making it an indispensable tool for large-scale pipeline projects.
These parameters determine the machine’s processing scope and quality, ensuring it aligns with diverse pipe fitting production needs:
Parameter Category | Specification Details |
---|---|
Elbow Diameter Range | Minimum: 325mm; Maximum: 1066mm (supports large-diameter elbow production for heavy-duty pipelines) |
Pipe Wall Thickness | 10-50mm (handles thick-walled pipes suitable for high-pressure, high-temperature scenarios) |
Bending Radius Range | 2.5D ≤ R ≤ 7D (D = pipe diameter; adjustable to match different elbow design standards, e.g., ANSI, DIN) |
Bending Angle Range | 0-90° (covers common elbow angles for pipeline direction changes) |
Pipe Wall Thinning Rate | <10% (avoids material weakening caused by excessive thinning during bending) |
Elbow Ellipticity | <10% (ensures uniform pipe cross-section, preventing flow obstruction in pipelines) |
Wave Degree (Heat-Affected Zone) | h/<2% (minimizes surface irregularities on bent pipe surfaces) |
Flatness (for 500mm Pipe Length) | <3mm (maintains straightness of pipe ends for smooth assembly with other fittings) |
Bending Radius Tolerance | <20mm (ensures consistency in batch production, reducing assembly errors) |
Bending Angle Error | ±1° (high precision for accurate pipeline layout) |
Compatible Pipe Materials | - Carbon steel seamless pipe: 20G, A106B, A106C - Alloy steel seamless pipe: 355P12, 15CrMo, 12Cr1MoV, P22, P91, WB36 - Straight seam welded pipe: Q235B, Q345B, X42, X52, X60, X65, X70, X80 |
Fixture Compatibility (Pipe Diameter) | 1066mm, 920mm, 820mm, 720mm, 630mm (quick fixture replacement for multi-size production) |
Machine Weight | 82 tons (robust steel frame ensures stable operation during heavy-duty bending) |
The main cylinder is the core power unit of the hydraulic system, directly influencing bending stability and force output:
Main Cylinder Parameter | Specification Details |
---|---|
Main Cylinder Thrust | 200 tons (2 cylinders total; provides sufficient force for bending thick-walled pipes) |
Structural Design | Piston structure with front and rear flanges (enhances sealing and load-bearing capacity) |
Test Pressure | 31.5Mpa (ensures cylinder safety under extreme working conditions) |
Working Pressure Range | 0-25Mpa (adjustable according to pipe material and thickness) |
Main Cylinder Inner Diameter | 250mm (optimized for balanced oil pressure distribution) |
Main Cylinder Outer Diameter | 273mm (thick cylinder wall for pressure resistance) |
Piston Rod Diameter | 190mm (high-strength design to avoid bending or deformation) |
Material of Cylinder Body | 45# steel (heat-treated for enhanced hardness and wear resistance) |
Effective Stroke of Main Cylinder | 10m (long stroke supports bending of long pipes without secondary positioning) |
