Large Diameter Hydraulic Pipe Bending Machine Series
Hydraulically driven; supports through-the-core bending; pipe diameter Φ75-Φ114mm; maximum wall thickness 10mm; suitable for industrial-grade mass production.
The Value of Hydraulic Pipe Bending Machines
When processing pipes, you may have encountered these problems: low efficiency in processing thick-walled pipes and high labor intensity for manual operation; high precision requirements for pipes used in fitness equipment, automotive structural parts, and engineering machinery, resulting in high scrap costs; fully automatic CNC pipe bending machines are too expensive, while manual equipment cannot meet production capacity demands.
Based on years of industry experience, if your production involves medium to large diameter pipes (Φ75-Φ114mm) and a thickness of 6-10mm, a hydraulic pipe bending machine is a more suitable choice. Our Hydraulic Pipe Bending Machine uses powerful hydraulic drive, enabling stable processing of thick-walled pipes, reducing reliance on manual labor, and improving production efficiency. It is also equipped with a microcomputer control system to ensure bending accuracy and reduce scrap caused by operational errors.
If you find CNC pipe bending machines too expensive and manual equipment inefficient, this type of semi-automatic hydraulic pipe bending machine achieves a better balance between cost, efficiency, and processing capacity.

Hydraulic Pipe Bending Machine Process Features
Based on years of experience in manufacturing pipe bending equipment, we believe the core of processing medium and large diameter pipes lies in the structural stability and long-term precision maintenance of the equipment.
Our Hydraulic Pipe Bending Machine employs a high-strength machine body structure, reducing welding and splicing to improve overall rigidity. When processing large diameter pipes and 6-10mm thick-walled pipes, the equipment experiences more stable stress, preventing deformation and precision degradation over long-term use.
The machine body has ample internal space, and the hydraulic system, motor, and control components are rationally arranged, facilitating maintenance and reducing downtime.
Furthermore, the stable structural design allows the equipment to maintain a bending accuracy of ±0.5° over the long term, effectively reducing scrap rates and meeting the mass production needs of industries such as fitness equipment, automotive structural parts, and construction machinery.
If you need a hydraulic pipe bending machine that can withstand high-intensity processing for extended periods, stability, durability, and ease of maintenance will be the most important considerations when selecting equipment.
Why Choose a Hydraulic Pipe Bending Machine for Large Diameter Pipes?
The larger the pipe diameter you’re processing, the more challenging the bending process becomes. As the diameter and wall thickness increase, the required bending torque increases rapidly, making it difficult for ordinary equipment to guarantee stable processing.
For pipes ≤Φ38mm, a standard NC pipe bending machine is sufficient; pipes Φ50-Φ63mm can be processed using a semi-automatic pipe bending machine. However, when processing medium to large diameter, thick-walled pipes exceeding Φ75mm, a stronger hydraulic drive and a precise control system are required.
Especially for large pipes ≥Φ114mm, not only is a high-pressure hydraulic system necessary, but also a high-rigidity machine body to withstand the enormous bending load.
Therefore, if your products involve medium to large diameter, thick-walled pipes, or high-strength structural components, choosing a Hydraulic Pipe Bending Machine ensures bending stability, processing efficiency, and a long service life.
DW75NC Hydraulic Pipe Bending Machine
Applications: Fitness equipment frames, outdoor furniture, large supports
When processing Φ50-Φ75mm thick-walled pipes, ordinary equipment often suffers from insufficient bending force, pipe deformation, and low production efficiency. The DW75NC is specifically designed for processing medium to large diameter pipes, supporting pipes up to Φ75mm × 6mm.
Utilizing hydraulic drive and a microcomputer control system, it achieves bending accuracy of ±0.5° and is equipped with an air-cooling system, eliminating the need for an additional water source and reducing maintenance costs.
If you are upgrading from manual pipe bending and want to improve efficiency but don’t want to invest in expensive CNC equipment, the DW75NC is a more economical and practical choice.
DW89NC Hydraulic Pipe Bending Machine
Applications: Automotive structural pipes, thick-walled steel pipes, engineering machinery fittings
When processing Φ75-Φ89mm pipes, many customers encounter problems such as insufficient bending force, wrinkling of thick-walled pipes, and poor product consistency.
The DW89NC supports pipe processing up to Φ89mm × 6mm. Utilizing a more powerful hydraulic system and a high-rigidity machine body, it can stably complete the bending of large-diameter, thick-walled pipes.
The equipment supports multi-bend program storage and is equipped with a core-through bending function, effectively reducing pipe deformation and improving the processing efficiency of complex pipe fittings.Based on years of pipe bending experience, if your product’s pipe diameter is concentrated between Φ75-Φ89mm, the DW89NC is an ideal choice balancing performance and investment cost.
DW114NC Industrial-Grade Hydraulic Pipe Bending Machine
Applications: Marine structural pipes, engineering machinery, large equipment fittings
When the pipe diameter reaches Φ100mm or larger, ordinary pipe bending machines often face problems such as insufficient power and poor equipment stability, requiring a more powerful hydraulic system.
The DW114NC has a maximum processing capacity of Φ114mm × 10mm. Employing a high-power hydraulic system and a reinforced machine body structure, it can stably process large-diameter, thick-walled pipes.
The equipment supports long pipes and large-radius bending, meeting the needs of one-time forming of large structural components.
If your production involves processing thick-walled pipes with a diameter of Φ100mm or more, it is recommended to choose the DW114NC directly to avoid affecting production efficiency later due to insufficient equipment capacity.
Hydraulic Pipe Bending Machine Selection Recommendations
Years of experience in pipe bending machine manufacturing tell us that choosing a hydraulic pipe bending machine shouldn’t be based solely on the maximum pipe diameter. Each increase in pipe diameter drastically alters the bending technology. The following three points will help you choose the right model:
1. Does your product require mandrel bending?
When processing thick-walled or large-diameter pipes, the biggest challenge is the potential for pipe wall deformation, wrinkling, and out-of-roundness during bending.
The mandrel’s role is to support the pipe’s internal structure during bending, maintaining pipe shape stability.
If your product consists of thin-walled pipes under Φ50mm, mandrel bending is usually unnecessary. However, if processing pipes over Φ75mm with a wall thickness of 4mm or more, or high-strength materials such as stainless steel or alloys, we recommend choosing a hydraulic pipe bending machine with mandrel bending functionality.
2. The number of bends in your product determines the model selection.
Many customers worry: If a single pipe has multiple bends, can a semi-automatic machine still meet production needs?
In practice, for most industrial pipe fittings, a semi-automatic hydraulic pipe bending machine is sufficient. Taking the DW89NC as an example, it supports multi-bend programming, can store multiple sets of product parameters, and can be quickly recalled after setup, reducing repetitive debugging time.
If your product involves multi-bend pipe fittings such as automotive structural tubing or fitness equipment frames, choosing a Hydraulic Pipe Bending Machine with program storage can improve production efficiency while reducing operational complexity.
3. How high a bending accuracy does your product require?
Many customers tend to overemphasize high precision when selecting equipment, but actual production requires judgment based on product requirements. For most industrial products, a bending accuracy of ±0.5° is sufficient for most assembly needs.
If your goal is to process medium to large diameter, thick-walled pipes, and you are concerned about stability, investment costs, and production efficiency, a Hydraulic Pipe Bending Machine is usually a more economical and practical choice than a fully automatic CNC machine. If your product requires very high precision, a fully automatic CNC pipe bending machine is recommended.
