• Produced in strict accordance with OEM drawing standards, the bending shape and installation hole position are consistent with original parts, direct installation without modification.
• Seamless steel pipe base material, uniform wall thickness, strong pressure resistance, not easy to burst under stable hydraulic pressure.
• Smooth inner wall, small flow resistance, reduce hydraulic system heat generation and energy loss.
• Fine surface anti-rust treatment, slow oxidation and rust speed, adapt to wet and dusty construction environment.
• Stable welding performance, good fit with matching flanges and pipe joints, high sealing reliability after assembly.
• High dimensional consistency of batches, convenient for warehouse stocking and on-site quick replacement.
• Strong vibration resistance, not easy to produce fatigue fracture under long-term machine vibration.

FAQ 

Q: What should I check before installing the steel pipe?
A: Check whether the pipe body has cracks, pits, rust, whether the inner cavity is clean and free of iron filings and debris, and confirm the alignment of the interface.

Q: Why does the steel pipe joint leak oil after installation?
A: It may be the flange surface is not flat, the sealing ring is damaged, the bolt tightening force is uneven, or the pipe deformation causes misalignment.

Q: What should be paid attention to when welding the steel pipe?
A: Control the welding heat input, avoid burning through the pipe wall, and clean welding slag inside and outside after welding to prevent impurities from entering the hydraulic circuit.

Q: What is the difference between hard pipe and high-pressure hose?
A: The steel hard pipe is suitable for fixed layout, good stability; the hose is used for parts with relative movement, which can absorb vibration.

Q: How to maintain the hydraulic steel pipe in daily use?
A: Regularly check for oil seepage, rust and deformation; avoid heavy impact on the pipe body during operation.
