High-Performance Hydraulic Machines for Industrial Applications

Tianjin Uranus' hydraulic pipe benders combine precision hydraulics with advanced controls to achieve accurate pipe forming. The bending cylinder (force up to 300 kN) uses a low-friction design with PTFE-impregnated seals (friction coefficient ≤0.08), while the bending radius is controlled via a servo-hydraulic system (repeatability ±0.3°). The machine accommodates pipes from 10 to 300 mm OD, with wall thicknesses up to 12 mm, and can achieve bend angles up to 180°. The hydraulic system features a proportional flow control valve for adjustable bending speed (0.1-10°/s), and a pressure relief valve set at 110% of working pressure for safety. A mandrel insertion mechanism with automatic retraction prevents ovality (deformation ≤1%), while the NC control system stores up to 100 bend profiles for quick changeovers. Constructed from ductile iron (QT700-2) for rigidity, the bender's frame includes anti-vibration mounts to reduce noise (<85 dB). Used in plumbing, automotive exhaust systems, and aerospace tubing, these benders meet ASME B31.1 and ISO 4422 standards. Optional CNC upgrades enable 3D pipe bending with multiple bends in a single setup. Contact us for pipe bending accuracy data or view bending process videos.
