Application：Pipeline for delivering compressed hot air from turbocharger to air cooler

• Fiber reinforced composite material, excellent high temperature resistance, can continuously bear hot compressed air from turbocharger, not easy to soften or deform.
• Integrated forming design of pipe body, flange and bell mouth, reduce assembly joints and lower the risk of air leakage.
• Good vibration absorption performance, buffer vibration transmitted from turbocharger and engine, reduce fatigue crack risk.
• Wear-resistant outer layer, effectively resist gravel scratch and dust erosion in engine compartment, extend service life.
• OEM contour and installation hole layout, fully consistent with original pipeline, no on-site modification required, shorten maintenance time.
• Good structural toughness, will not crack easily under pressure fluctuation caused by frequent acceleration and deceleration.
• Stable sealing performance with matched clamps and gaskets, effectively prevent compressed air escaping.
• Batch air tightness inspection before delivery, every pipe passed pressure test to avoid sudden air leakage on construction

FAQ 

Q：What signs mean the air cooler intake pipe needs replacement?
A：Visible cracks on pipe surface, bulging, air leakage at flange or bell mouth joint, pipe hardening or softening, obvious deformation under working pressure.

Q：What should be noted during air cooler intake pipe installation?
A：Clean the connecting surface before installation; align flange holes and tighten bolts evenly; install hose clamps properly at bell mouth; avoid sharp bending or twisting the pipe. Keep pipe away from high-temperature exhaust parts and sharp metal edges.

Q：What are common causes of air cooler intake pipe damage?
A：Long-term high temperature aging; vibration fatigue from turbocharger; friction with surrounding metal components; improper installation with excessive bending; over-tightened bolts causing flange crack.

Q：Can leaking air cooler intake pipe be repaired and reused?
A：Not recommended. Adhesive repair or wrapping will fail quickly under high temperature and pressure fluctuation. Replace new pipe directly once cracks or air leakage appear.

Q：How to inspect air cooler intake pipe during daily maintenance?
A：Check pipe surface for cracks, swelling and air leakage before heavy-load operation. Inspect tightness of flange bolts and hose clamps. Focus inspection on flange and bending areas, these parts are most vulnerable to aging and leakage.

Q：Can this air cooler intake pipe fit other loader models?
A：This air cooler intake pipe is custom made for ZL50G/ZL50GL. Length, inner diameter and flange hole layout are exclusive. It cannot be fitted directly on other models without modification. Wrong replacement will cause poor sealing and air leakage.
