The YD12-003 20T Pipe Bender is an industrial-grade heavy equipment designed to address the pain points of "difficulty in bending large-diameter thick-walled pipes under heavy working conditions, inability to meet long-stroke deep bending needs, and high requirements for bending angle accuracy". With "20-ton ultra-high pressure system + 288mm extra-long stroke + 8 full-specification dies" as the core, it balances high-pressure strength, stroke coverage and precision control, solving problems of traditional pipe bending equipment such as "inability to press thick-walled large pipes, insufficient deep bending stroke, and easy angle deviation". It provides a reliable solution for heavy-duty pipeline construction in large-scale industry, municipal engineering and other fields, with core advantages as follows:
- 20-Ton Ultra-High Pressure Output, No Pressure for Thick-Walled Large Pipes
The equipment is equipped with a heavy-duty hydraulic drive system, with a rated output pressure of 20 tons, enabling wrinkle-free and crack-free bending of hard-to-bend pipes such as 3" thick-walled steel pipes (8mm wall thickness) and 2-1/2" high-pressure alloy pipes:
- Strong Adaptability to Heavy Working Conditions: For 3" thick-walled steel pipes that traditional 16-ton pipe benders "cannot press or bend without deformation", the 20-ton pressure acts evenly on the pipe through hydraulic pressure boosting. Slow pressure application allows the pipe to deform naturally along the die arc, avoiding rupture caused by excessive local stress. The pipe bending qualification rate is over 99.5%, meeting the "defect-free installation" standard for industrial high-pressure pipelines.
- Excellent Pressure Stability: Adopting a dual-cylinder synchronous hydraulic structure, the pressure rises steadily (pressure rise rate 5MPa/s). After 50 consecutive bending cycles, the pressure attenuation is ≤2%, ensuring the consistency of bending angles for pipes of the same batch, reducing angle errors during subsequent pipeline connection and lowering project rework rate.
- 288mm Extra-Long Stroke, Covering All Deep Bending Needs
The ram stroke reaches 288mm, which is 107% higher than that of conventional models (139mm). It can fully cover the full-circumference deep bending of 3" large-diameter pipes, solving the problem of "angle deviation and pipe damage caused by segmental bending":
- One-Time Forming for Deep Bending of Large Pipes: When bending a 3" thick-walled steel pipe, the 288mm stroke can complete 90° deep bending at one time without mid-stop or segmental operation. The bending time for a single pipe is shortened from 15 minutes to 6 minutes, with efficiency increased by 60%; for complex pipes requiring "U-bends" and "multi-angle continuous bends" (such as ship pipelines), the long stroke can reduce the number of die replacements, adapting to complex construction scenarios.
- Flexible Stroke Adjustment: The stroke can be precisely set through the operation panel (adjustment accuracy 1mm). Corresponding strokes are adjusted for pipes of different diameters (e.g., 1/2" thin-walled pipes, 3" thick-walled pipes) to avoid energy waste due to excessive stroke or poor bending effect due to insufficient stroke.
- 8 Full-Specification Dies + Bidirectional Self-Locking, Precise Bending for Multi-Diameters
- Seamless Adaptation to Multi-Diameters: 8 dies cover 1/2"-3" common diameters. The inner hole of the die is precision honed (accuracy ±0.03mm), perfectly fitting the outer wall of the pipe, with no scratches or wrinkles during bending. For example, when bending a 1-1/2" copper alloy pipe, the roundness retention rate at the bending angle is ≥95%, meeting the high requirements for pipeline fluidity in ships, power stations and other scenarios; the die adopts a "snap + positioning pin" quick-fixing structure, no tools are needed for replacement, and switching from a 1/2" die to a 3" die takes only 1 minute, which is 5 times more efficient than traditional screw-fixed dies.
- Bidirectional Self-Locking for Precision: The workbench is equipped with a bidirectional self-locking mechanism. After setting the bending angle, it is fixed by both mechanical locking and hydraulic locking. The ram will not deviate due to pipe reaction force during work. For example, when precise 30° connection is required for municipal heating networks, 20 consecutive pipe bends after angle locking have an angle deviation of ≤0.5°, meeting the "seamless connection" requirement of the pipeline network.
- Heavy-Duty Structure + Humanised Design, Safe, Durable and Easy to Operate
- Heavy-Duty Body for Stability: The machine body is integrally welded with 4mm-thick cold-rolled steel plates, combined with a "cross-shaped" reinforcing rib. The overall torsional strength reaches 1000N·m, and the body has no shaking or deformation when bending a 3" thick-walled steel pipe; 8 anti-slip foot pads (friction coefficient ≥0.9) are installed at the bottom to enhance adhesion to the ground and prevent equipment displacement during construction; optional moving casters are available, allowing 2 people to push the equipment for short-distance movement on the construction site, adapting to the "multi-station rotation work" scenario.
- Labor-Saving Operation to Reduce Burden: Equipped with an extended labor-saving operating handle (40cm in length), which can reduce the operating force by 50% using the principle of leverage, avoiding operator fatigue caused by excessive force; the handle is equipped with an anti-slip rubber cover (anti-slip pattern depth 1mm), which does not slip even if hands are stained with oil; lifting holes are reserved on the side of the body, facilitating long-distance transportation with forklifts or cranes, solving the "difficult transportation" problem of the 99kg equipment.

Municipal Engineering Heating Network Laying
The municipal department lays the main heating pipeline (using 3" galvanised pipes with 6mm wall thickness) for the new urban area, requiring 80 straight pipes to be bent at 90° for pipeline direction change. The YD12-003 is used: Install the 3" dedicated die, set the bending angle to 90°, the 20-ton pressure easily bends the galvanised pipes, and the 288mm long stroke ensures one-time forming; the bidirectional self-locking function ensures consistent bending angles of each pipe, which perfectly connects with valves and flanges during installation. The bending time for a single pipe is shortened from 12 minutes to 5 minutes, and 80 pipes are completed in only 6.5 hours, adapting to the "batch large-diameter pipeline network laying" scenario.

Steam Pipeline Construction in Large Power Stations
A power station installs steam pipelines (high-temperature resistant 2-1/2" steel pipes with 8mm wall thickness) for a 1000MW unit, requiring 30 45° angles to be bent for pipeline avoidance of equipment. The YD12-003 is used: Replace with the 2-1/2" die, lock the 45° angle via the dial, and the 20-ton stable pressure output avoids steel pipe rupture due to the high-temperature material characteristics; the precise fit of the die ensures no deformation of the bending angle, meeting the "high-pressure and high-temperature resistance" requirements of steam pipelines, adapting to the "precision construction of high-temperature and high-pressure pipelines" scenario.

Ship Pipeline System Transformation
A shipyard transforms the fuel pipeline of a 10,000-ton cargo ship (using corrosion-resistant 2" alloy pipes with 5mm wall thickness), requiring 15 complex angles (30°, 60°, 90°) to be bent for layout in the cargo hold. The YD12-003 is used: Adjust the dial quickly according to angle requirements, and the 288mm long stroke adapts to the deep bending needs of alloy pipes; the bidirectional self-locking ensures the precision of bending at different angles, avoiding the impact of pipe angle deviation on fuel delivery efficiency, adapting to the "complex ship pipeline transformation" scenario.

Hydraulic Pipeline Maintenance of Heavy Machinery
A construction machinery factory repairs the hydraulic pipeline of a 50-ton excavator (using high-pressure 1-1/2" steel pipes with 7mm wall thickness), requiring the damaged section of the pipeline to be bent at 60° for replacement. Maintenance personnel use the YD12-003: Install the 1-1/2" die, set the 60° bending angle, and the 20-ton pressure completes the bending at one time; the equipment can be temporarily fixed in the maintenance workshop without a dedicated site, adapting to the "emergency maintenance of heavy machinery pipelines" scenario.
A1: It will cause equipment overload and die damage, and operation is strictly prohibited. The 3" die is rated for steel pipes with wall thickness ≤8mm. A 9mm wall thickness exceeds the load limit of the equipment and die. Forced bending will cause the inner hole of the die to collapse, ram bending, and even rupture of hydraulic system seals; if bending a 3" steel pipe with 9mm wall thickness is required, a dedicated ultra-thick-walled die (confirm equipment compatibility by contacting the manufacturer) must be customized, and the hydraulic system pressure components must be upgraded to avoid irreversible damage caused by over-specification use.
A2: Auxiliary tools are recommended to reduce transportation difficulty. ① Optional equipment moving casters (provided by the manufacturer, installed at the bottom of the body) can be used, allowing 2 people to push the equipment on flat ground, with a 100-meter transportation time of about 5 minutes; ② If the ground is uneven, a forklift (via the body lifting holes) or a manual hydraulic truck can be used to transfer the equipment to the workstation smoothly; ③ Single-person hand carrying is strictly prohibited to avoid waist strain or equipment tipping.
A3: It is mostly due to high pipe material elasticity or too fast pressure application, which can be handled in the following steps: ① Check the pipe material. For high-elastic alloy pipes, stainless steel pipes, etc., a 2°-3° compensation angle should be added to the set angle (e.g., set 92° for a required 90° angle) to offset the springback; ② If the compensation angle is ineffective, reduce the pressure application speed (from 5MPa/s to 3MPa/s) to give the pipe enough time to adapt to deformation and reduce springback; ③ For pipes with large springback (such as spring steel), local low-temperature tempering (200℃-300℃) can be performed after bending to stabilize the bending angle shape (requires professional operation).
A4: It is mostly due to seal aging or loose joints, which can be checked in the following steps: ① Turn off the equipment power, release the hydraulic system pressure, and check if the hydraulic pipe joints are loose. If loose, tighten them with a wrench (torque 25N·m); ② If the joints are not loose, disassemble the seals at the oil leakage part (such as cylinder seals, pipe joint gaskets) and replace them with original seals provided by the manufacturer (avoid using non-original parts leading to poor sealing); ③ After replacement, add special hydraulic oil (46# anti-wear hydraulic oil), start the equipment and run it empty 10 times, and check if there is still oil leakage; if oil leakage persists, contact the manufacturer for on-site maintenance of the hydraulic cylinder or oil pump to avoid fault expansion.
