FAQ 

Q：What signs mean the pipe needs replacement?
A：Pipe body crack, weld leakage, serious rust and perforation, pipe deformation, sealing flange damage leading to oil leak.

Q：What should be noted during pipe installation?
A：Clean pipe, filter and tank connecting surface before installation; install new rubber gaskets; fasten fixing bolts evenly; avoid strong bending or knocking the pipe during assembly.

Q：What are common causes of pipe damage?
A：Long-term vibration fatigue; external impact collision; paint peeling followed by rust corrosion; aging and hardening of sealing gaskets; friction with surrounding parts.

Q：Can cracked pipe be welded and reused?
A：Temporary welding repair only works for emergency. Welded areas easily crack again under continuous vibration. It is recommended to replace new pipe for long-term safety.

Q：How to inspect pipe during daily maintenance?
A：Check pipe surface rust, cracks and oil leakage before heavy-load operation. Focus inspection on welding seams and both-end flanged connections.

Q：What failures will a failed pipe cause?
A：Damaged pipe causes hydraulic oil leakage and oil shortage. Insufficient oil circulation will reduce filtering efficiency and accelerate wear of hydraulic pumps and valves.

Q：Can this pipe fit other loader models?
A：This pipe is custom made for ZL50G/ZL50GL. Total length, bending shape and pipe diameter are exclusive. It cannot be fitted directly on other models without modification. Wrong replacement will lead to assembly mismatch and oil leakage.
