Applicable Scenarios

It is used for the fixed hydraulic oil circuit on the right side of the loader, often matched with hydraulic circuits such as boom, bucket and pilot control. Widely applied in continuous heavy-duty operation scenarios such as mines, sand yards, construction sites and cargo yards.

• Original bending size, angle, length and mounting holes are fully consistent with the original machine for easy alignment
• Seamless steel pipe base material with high rigidity, resistant to pulse high pressure, no risk of bulging or delamination failure like rubber hoses
• Anti-rust spraying process, corrosion and impact resistant, suitable for harsh construction sites with dust and splashing muddy water
• Smooth and firm welding seam with stable sealing performance, not easy to leak oil during long-term operation
• Pressure test for each pipe before delivery to eliminate parts with trachoma and weld defects for stable quality
• Longer service life than hydraulic hoses, reducing maintenance cost from frequent replacement
• Matched with flanges and fittings of the same series, convenient for pipeline assembly and maintenance stock

FAQ 

Q：How to deal with oil leakage at the weld of steel pipe?
A：Oil leakage at welds is mostly caused by trachoma or crack. On-site welding repair is not recommended. Replace with a new steel pipe directly to avoid massive oil leakage caused by weld burst.

Q：Can I bend the steel pipe by myself to adjust the angle for installation?
A：Self-bending is not recommended. Unauthorized bending will cause inner wall wrinkles, reduce flow diameter, lead to pressure fluctuation or pipe cracking. Use finished steel pipe of corresponding part number.

Q：Will paint peeling and rust on steel pipe surface affect usage?
A：Light surface rust can be polished and repainted for protection. If corrosion is deep and the pipe wall becomes thin, replace it in time to prevent rupture under high pressure.

Q：What should be noted when disassembling and assembling steel pipe?
A：Release system pressure and drain hydraulic oil before disassembly. Align flange sealing surface, place gasket correctly and tighten bolts diagonally and evenly to avoid leakage caused by uneven wear.

Q：How to match steel pipe and hose in hydraulic circuit?
A：Steel pipes are preferred for fixed positions, and hydraulic hoses are used for positions with large vibration and displacement. The combination balances strength and shock absorption.

Q：What are the storage requirements for spare steel pipes?
A：Store in dry and ventilated warehouse, avoid rain exposure. Seal pipe ends to prevent sediment and debris from entering and blocking the oil circuit.
