Thick-walled tube high-pressure hydraulic steel pipes are indispensable components in industries where fluid transmission systems must endure extreme pressures, mechanical stress, and environmental challenges. These pipes, characterized by their robust construction and material properties, are engineered to deliver reliability and efficiency in critical applications.
The pipes are manufactured from high-grade carbon and alloy steels, each offering unique mechanical properties tailored to specific operational demands: The main materials include common grades such as 20#, ST35, ST45, ST52, E235 and E355.
Size
The pipes are available in a range of standard sizes, optimized for high-pressure performance, with customization options to meet specific requirements:
Common Standard Sizes:
ID 4.4mm, OD 12mm:
ID 5.4mm, OD 12mm:
ID 5.4mm, OD 15mm:
ID 6.3mm, OD 15mm:
ID 6.3mm, OD 16mm:
ID 7.55mm, OD 16mm:
Tailored Dimensions: Pipes can be manufactured to specific inner and outer diameters, wall thicknesses, and lengths to match unique system designs.
Material Selection: Customers can choose from a range of steels based on strength, corrosion resistance, and weldability requirements.
Surface Treatments: Options include bright annealed phosphating or zinc plating to enhance corrosion resistance and wear performance.
High-Pressure Resistance:
Thick-walled design and high-strength materials enable the pipes to withstand internal high pressures, depending on the grade and dimensions.
Dimensional Precision:
Cold-drawing processes ensure tight tolerances (e.g., ±0.05 mm for ID and OD), critical for hydraulic systems requiring precise fluid control.
Smooth Surface Finish:
Inner diameter roughness below Ra 0.8 μm minimizes friction and pressure drop, improving system efficiency.
Corrosion and Wear Resistance:
Surface treatments and material selection enhance durability in harsh environments.
Weldability and Formability:
Materials like 20#, ST35, and ST52 offer good weldability, facilitating easy integration into complex hydraulic assemblies.
Automotive Engineering:
Used in high-pressure fuel injection systems, brake lines, and hydraulic actuators, where precision and reliability are critical.
Aerospace:
Employed in flight control systems, landing gear, and hydraulic actuators, requiring lightweight yet high-strength components.
Oil and Gas:
Critical in drill strings, subsea pipelines, and hydraulic fracturing systems, where pipes must withstand extreme pressures and corrosive fluids.
Heavy Machinery:
Integrated into hydraulic cylinders, excavators, and cranes, where thick-walled pipes provide the durability needed for heavy lifting and operation.
Industrial Automation:
Used in robotic arms, CNC machines, and hydraulic presses, where precise fluid control and high-pressure resistance are essential.
Medical and Laboratory Equipment:
Miniature hydraulic systems (e.g., ID 4.4mm, OD 12mm) are used in precision medical devices and lab automation.
Thick-walled tube high-pressure hydraulic steel pipes, crafted from materials like 20#, ST35, ST45, ST52, E235, and E355, represent the pinnacle of engineering precision and reliability.
