One-stop Bending Solutions For Wires, Tubes And Pipes
In the process of ship manufacturing and maintenance, pipe bending machines are mainly used for bending various types of pipes to meet the complex requirements of pipeline layouts in different systems.
In the field of shipbuilding, pipe bending machines are one of the core equipment and are applied to various key systems, specifically as follows:
| Ship Part | Specific application scenarios | Role of pipe bender | Typical Tubes |
| Power System | Main engine fuel pipe, lubricating oil pipe, cooling water pipe, exhaust pipeline | Processing a specific angle, adapt to the space, to ensure power transmission | Stainless steel pipe, copper pipe, high temperature resistant alloy pipe |
| Piping System | Ballast water pipe, bilge water pipe, fire water pipe, domestic water pipe | Bending arrangement along the hull structure to ensure the function of the pipeline | Galvanized steel pipe, stainless steel pipe |
| Ventilation & Air Conditioning | Cabin ventilation pipe, cargo hold ventilation pipe, refrigerant pipe, condensate pipe | Production of elbow connection, suitable for the cabin structure | Galvanized iron duct, copper pipe |
| Hull Structure & Outfitting | Handrail, mast support, crane support pipe | Bending and molding to enhance structural strength | Carbon steel, aluminum alloy pipe |
| Specialty Ship Systems | LNG ship low-temperature piping, chemical ship corrosion-resistant piping | High-precision bending to meet special environmental requirements | Low-temperature alloy pipe, corrosion-resistant stainless steel pipe |
In the ship’s power system, components such as fuel pipes, lubricating oil pipes, and cooling water pipes of the main engine require precise processing by pipe bending machines. For example, the fuel pipes of diesel engines in large cargo ships are bent to adapt to the layout of the engine room, ensuring fuel delivery. Approximately 70% of the pipelines in the power system need to be bent, and the processing accuracy affects power transmission.
The ballast water pipes, bilge water pipes, and other components of the pipeline system are distributed throughout the ship’s hull and need to be bent along the ribs and longitudinal girders. The bilge water pipes of cruise ships are processed by pipe bending machines to ensure drainage, and the number of bent pipes in the pipeline system of merchant ships can reach thousands.
Ventilation pipes, refrigerant pipes, and other components of the ventilation and air conditioning system require pipe bending machines to create elbows for connection and installation. The cargo hold ventilation pipes of container ships are processed to ensure cargo ventilation.
Different types of pipe bending machines have their own advantages: CNC pipe bending machines have high precision and strong automation, suitable for precision pipelines in power systems; hydraulic pipe bending machines have large bending force, suitable for processing large-diameter and thick-walled pipes.
Shanghai ANTISHICNC CNC275RHS+RBH-6A Hydraulic and Electric CNC Pipe Bending Machine
CNC275RHS+RBH-6A not only features high bending precision but also is suitable for ship pipelines with large diameters and thick walls. The machine adopts a high-rigidity mechanical structure, optimizing the layout of the bending arm and head to reduce interference. The program control system supports batch high-precision bending and single-mold automatic pipe bending, with a maximum of 50 bends per pipe. The equipment is driven by a 6-axis servo system (feeding/rotation/slide/mandrel/fixture) + 2-axis Rexroth proportional valve control (bending/boosting), equipped with robot-grade reducers for high precision and long service life.
It has functions such as quick mold change, mandrel slow retraction to prevent bulging, automatic lubrication, and modular circuit maintenance. Safety configurations include overload protection, emergency stop buttons, password permissions, mechanical limit switches, and abnormal alarm systems.
Standard accessories include a mandrel, shock-absorbing feet, an oil cooling system (no external cooling required), an accessory tool kit, and a Chinese manual. With a compact and stable structure, it is suitable for processing complex steel pipes, balancing efficiency and safety, and ideal for high-precision mass production.
