Applicable Model: XCMG ZL50G, ZL50GL Wheel Loader
Material: Seamless carbon steel pipe
Surface Treatment: Anti-rust painting
Connection Type: Welded flange connection
Transmission Medium: Construction machinery hydraulic oil
Applicable System: Left-side hydraulic oil circuit of loader
Working Temperature: -20℃ ~ +100℃
Inspection Items: Dimension inspection, weld flaw detection, high-pressure sealing test

Applicable Scenarios

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

• Original bending dimension, angle, length and flange holes consistent with original machine for easy alignment
• Seamless steel pipe material with good rigidity, resist high-pressure pulse and longer service life than hydraulic hose
• Firmly welded flange with stable weld, not easy to leak oil under long-time pressure
• Smooth inner pipe wall, low oil flow resistance, guarantee stable oil supply and powerful hydraulic action
• Strong adhesion anti-rust coating, resist muddy water and dust corrosion on construction site
• Pressure test and flaw detection for each pipe before delivery, eliminate trachoma and cold weld defects
• Standard spare part, convenient for stock and replacement, reduce equipment downtime

FAQ 

Q：What causes oil leakage at the flange of the left steel pipe?
A：It is mostly caused by aged gasket, sediment on flange surface or uneven bolt tightening. If leakage comes from weld crack, on-site welding repair is not recommended, replace the whole pipe directly.

Q：Can the steel pipe be used after dent caused by collision?
A：Dents reduce flow diameter, lead to pressure loss and weak lifting, and weaken pipe wall strength which may burst under high pressure. Replace it once dented.

Q：Must I replace the steel pipe if it gets rusty?
A：Light surface rust can be polished and repainted. If the pipe wall is thinned with rust pits and strength declines, replace it in time.

Q：What should be noticed when disassembling and installing this steel pipe?
A：Release hydraulic pressure and drain residual oil before disassembly. Clean flange surface, lay gasket flat and tighten bolts diagonally step by step to avoid leakage.

Q：Can this left hard steel pipe be replaced by hydraulic hose?
A：Direct replacement is not recommended. This circuit bears heavy pressure pulse and is originally designed as hard pipe. Hoses will age and burst rapidly here with safety risks.

Q：What are the storage requirements for steel pipe spare parts?
A：Store in dry and ventilated warehouse, protect flange surface from impact deformation, seal both pipe ends to prevent sediment blocking oil circuit and jamming valves.
