The YD12-004 12Ton Air/Hydraulic Pipe Bender is an efficient equipment designed to address the pain points of "traditional manual pipe benders being laborious, poor adaptability of single drive mode, and insufficient accuracy of wide-angle pipe bending". With "12-ton air-hydraulic linkage drive + 90°-180° wide-angle adjustment + 6 full-specification dies" as the core, it balances labor-saving operation, scenario adaptability and precision control, solving the problems of "tiring manual pipe bending, limitations of single drive, and inaccurate large-angle bending". It provides a flexible and reliable pipe bending solution for maintenance, home decoration, industry and other scenarios, with core advantages as follows:
- 12-Ton Air-Hydraulic Dual Drive, Balancing Labor Saving and Efficiency
Adopting a "pneumatic pressure boosting + hydraulic output" linkage structure, it has significant advantages over pure manual or pure pneumatic pipe benders:
- Labor-Saving Operation Reduces Burden: Driven by 0.6-0.8MPa workshop air source, operators only need to control the pneumatic switch to complete pressure application, saving 70% more effort than pure manual pipe benders (requiring manual pressure application); even in scenarios without air source, emergency operation can be performed through manual hydraulic rod. Bending a single 2" thick-walled steel pipe takes only 30 seconds, which is 3 times more efficient than manual models.
- Stable Output Ensures Quality: The air-hydraulic linkage system has a stable pressure rise (pressure rise rate 3MPa/s). After 30 consecutive bending cycles, the pressure attenuation is ≤4%, avoiding the problem of "large pressure fluctuation and bending angle deviation" of pure pneumatic models. The pipe bending qualification rate is over 98%, meeting the pipe bending quality requirements of multiple scenarios.
- 90°-180° Wide-Angle Adjustment, Covering Complex Pipe Bending
Breaking the limitation of traditional pipe benders (maximum 90° bending angle), it supports arbitrary angle bending between 90°-180°, adapting to complex needs such as semi-circle (180°) and obtuse angle (120°-179°):
- Precise Angle Control Without Deviation: The workbench is equipped with a 90°-180° dial (positioning points every 5°, accuracy ±1°). During adjustment, the angle is locked by a positioning pin. For example, when a 180° U-bend is required for an automobile exhaust pipe or a 135° oblique bend for home decoration pipelines, precise forming can be achieved with one lock without repeated test bending, and the angle deviation is ≤0.5°.
- Long Stroke Adapts to Deep Bending: For 180° full-circular pipe bending needs, the equipment's ram stroke is optimized (approx. 150mm), which can fully cover the full-circumference bending of 2" diameter pipes, avoiding "incomplete bending angle and pipe jamming" caused by insufficient stroke. For example, when bending a 1-1/2" stainless steel pipe at 180°, it can be completed with one pressure application without segmental operation.
- 6 Full-Specification Dies, Seamless Switching Between Multi-Diameters
Equipped with 6 precision dies covering 1/2"-2" common pipe diameters, adapting to pipeline specifications of multiple scenarios:
- Precise Fit Without Damage: The inner hole of the die is honed (accuracy ±0.05mm), perfectly fitting the outer wall of the pipe, with no scratches or wrinkles during bending. For example, when bending a 1" copper alloy pipe at 180°, the roundness retention rate at the bending angle is ≥92%, which does not affect the pipeline fluidity.
- Quick Disassembly and Replacement Saves Time: The die adopts a "snap + positioning slot" dual fixing structure, no tools are needed for replacement, and disassembly and assembly can be completed with one hand. Switching from a 1/2" die to a 2" die takes only 40 seconds, which is 4 times more efficient than traditional screw-fixed dies. The dies are equipped with storage slots to avoid loss, adapting to the "alternating work with multiple pipe diameters" scenario.
- Lightweight Design + Safety Details, Double Protection for Mobility and Safety
- 36kg Lightweight for Easy Movement: With a net weight of only 36kg, it can be carried by an adult male with one hand, with no pressure to move from the warehouse to the construction workstation 20 meters away. Compared with pure hydraulic pipe benders of the same tonnage (mostly over 50kg), the mobility is increased by 40%, adapting to "multi-station rotation and outdoor temporary work" scenarios; 4 anti-slip foot pads are installed at the bottom of the body to prevent equipment displacement during bending and ensure operation safety.
- Safety Protection Without Hidden Risks: The air-hydraulic system is equipped with an overload protection valve (automatic pressure relief when pressure exceeds 12 tons) to avoid equipment damage caused by overpressure; the operating handle is equipped with an anti-slip rubber cover (friction coefficient ≥0.8), which does not slip even if hands are stained with oil; the air source interface is equipped with a one-way valve, and the hydraulic system maintains pressure when the air source is disconnected to prevent pipe springback and improve operation safety.

Exhaust Pipe Bending in Auto Repair Shops
An auto repair shop repairs the exhaust pipe of a Volkswagen Lavida (1-1/4" stainless steel pipe with 1.5mm wall thickness), requiring a 180° U-bend to connect to the chassis. The YD12-004 is used: Install the 1-1/4" die, adjust the angle to 180°, connect to a 0.7MPa air source, and the air-hydraulic system quickly applies pressure to complete bending; the 36kg lightweight body can be flexibly moved in the maintenance workstation, and the bending time for a single exhaust pipe is shortened from 10 minutes to 3 minutes, adapting to the "precision bending of automobile exhaust pipes" scenario.

Large-Radius Pipeline Laying in Home Decoration Water and Electricity Transformation
A home decoration company conducts water and electricity transformation for a villa, requiring 20 2" galvanised pipes to be bent at 120° large radius for ceiling pipeline layout in the living room. The YD12-004 is used: Replace with the 2" die, lock the 120° angle, and easily bend with the help of air-hydraulic drive; no large equipment is needed, and it can be operated in the narrow ceiling space. The bending angle is precise without deviation, and it perfectly connects with pipeline fittings during installation, adapting to the "large-radius pipe bending in small home decoration spaces" scenario.

Exhaust Pipeline Processing of Commercial Kitchen Utensils
A kitchen utensil manufacturer processes the exhaust pipeline of a hotel kitchen (1" stainless steel pipe with 1mm wall thickness), requiring a 180° bend for joint connection. The YD12-004 is used: Replace with the 1" die, adjust to 180° angle, and the air-hydraulic drive realizes rapid forming; the precise fit of the die ensures no scratches on the outer wall of the pipeline, and there is no resistance during exhaust, adapting to the "precision wide-angle bending of thin-walled metal pipes" scenario.
A1: Manual bending is not recommended; air-hydraulic dual drive is more suitable. Bending a 2" steel pipe with 5mm wall thickness requires 10-12 tons of pressure. Manual operation requires continuous application of large force (approx. 300N), which is not only laborious but also may cause pipe deformation and die deviation due to uneven pressure; when there is no air source, it is recommended to prioritize manual emergency bending of small-diameter (≤1") thin-walled pipes. For 2" thick-walled pipes, an air source must be connected, and air-hydraulic drive should be used to ensure the pipe bending effect and equipment safety.
A2: Auxiliary tools are recommended, and single-person carrying requires caution. 36kg is equivalent to 72 bottles of 500ml mineral water. Single-person carrying by females may easily cause waist strain; it is recommended to use a folding trolley, place the equipment sideways on the trolley, and use the handrail for assistance when carrying through stairs, or use a freight elevator; for short-distance (within 5 meters) movement, hold the handles on both sides of the body with both hands and move slowly, avoiding direct lifting.
A3: It is mostly due to incorrect die adaptation or too fast pressure application, which can be checked in the following steps: ① Check if the die specification matches the pipe diameter. For example, using a 1-1/2" die to bend a 2" pipe causes wrinkles due to excessive gaps; the corresponding specification die must be replaced immediately. ② If the die is properly adapted, reduce the pressure application speed (from 3MPa/s to 1.5MPa/s) to give the pipe enough time to deform along the die arc and avoid local extrusion wrinkles. ③ For thin-walled pipes (wall thickness ≤1.5mm), an anti-wrinkle mandrel (available from the manufacturer) can be inserted into the pipe to enhance the pipe's anti-deformation ability.
A4: It is mostly due to air source impurity blockage or hydraulic oil aging, which can be handled in the following steps: ① Turn off the air source, disassemble the air source interface filter, and blow off impurities with compressed air (cleaning is recommended every 3 months). ② Check the hydraulic oil level. If it is below the minimum scale line, add 46# anti-wear hydraulic oil (the oil level must be between the scale lines). ③ If the filter is cleaned and oil is added but the speed is still slow, disassemble the cylinder intake valve, wipe the valve core with alcohol (to remove oil stains), reinstall and test; if the fault persists, contact the manufacturer to replace the pneumatic seal ring (priced at 30 yuan/set), which can be replaced without professional tools.
