product parameters

- Product Name: Steel Pipe
- Part Number: 252100357
- Applicable Equipment: XCMG ZL50G, ZL50GL Wheel Loader
- Main Material: Seamless hydraulic steel tube
- Manufacturing Process: Tube cutting, CNC bending, end machining, joint welding, weld inspection, pressure test, anti-rust coating
- Surface Treatment: Anti-rust paint coating
- Installation Position: Fixed hydraulic circuit of loader
- Fastening Method: Connected by flanges or fittings, secured to frame by pipe clamps
- Supply Note: Single steel pipe assembly supplied; sealing rings, pipe clamps and bolts are separately optional parts
- Functions: Conduct high-pressure hydraulic fluid, form fixed hydraulic circuits, transmit hydraulic power and stabilize actuator movement
- Working Conditions: Sand and stone yards, mines, earthwork infrastructure, mixing plants, material transfer yards and other heavy-duty vibrating operation sites

• Bending angle, overall length and joint position match original pipes for great interchangeability, no on-site rework
• Seamless steel tube with high pressure resistance, resistant to bulging under pressure shock
• CNC one-shot bending with smooth curves, low flow resistance
• Welded joints inspected by flaw detection for strong vibration resistance
• Anti-rust coating against gravel erosion, longer service life than rubber hoses
• Rigid structure with stable positioning, reducing cyclic stress and leakage at seals
• Pressure tested before delivery to eliminate weld leakage risks
• Perfectly fitted to original mounting points of ZL50G/ZL50GL without interference with surrounding parts

FAQ 

Q1: Can this steel pipe fit ZL50GN loader directly?
A1: Part No.252100357 only fits ZL50G and ZL50GL. ZL50GN has different hydraulic layout. Verify part number, shape, diameter and fittings before use to avoid interference and leakage.

Q2: Can the pipe with thinned rusted wall or dents keep working?
A2: Not recommended. Dents and thin rusty walls reduce pressure resistance and may burst under high pressure. Replace it immediately.

Q3: Are pipe clamps and sealing rings included in shipment?
A3: No. Clamps, seals and bolts are optional. Replace seals together with pipe, as aged seals tend to leak slowly.

Q4: How to troubleshoot oil leakage at welds or flanges after installation?
A4: Check bolt torque, seal condition, sealing surface and welds. Replace the whole pipe if weld cracking occurs.

Q5: What precautions should be taken during pipe installation?
A5: Clean sealing surfaces. Do not force alignment. Secure with clamps and keep clearance. Test under idle pressure and recheck leaks.

Q6: What is the difference between rigid steel pipe and rubber hydraulic hose? When to use this steel pipe?
A6: Rigid pipes are for static fixed circuits, rubber hoses for swinging parts like booms. This pipe is for static chassis and valve compartment circuits of ZL50G/ZL50GL.
