How to Extend the Service Life of Fuel Tank Trucks: Maintenance Guide

1. Tank Shell & Corrosion Control

• Drain Sumps Daily: Remove accumulated water and moisture condensation daily to prevent interior pitting corrosion.

• Clean & Flush Bi-Annually: Wash internal compartments at least twice a year to remove fuel sediment and sludge.

• Inspect Saddle Rubber Pads: Check and replace worn rubber pads between the chassis and tank saddles to eliminate metal-to-metal friction.

• Touch Up Coatings: Inspect internal linings and external paint layer for scratches; repaint exposed metal immediately.

2. Valves, Seals & Safety Systems

• Replace Gaskets Regularly: Inspect and swap swollen or hardened Viton/PTFE manhole gaskets to prevent fuel seepage.

• Test Emergency Foot Valves: Actuate pneumatic bottom emergency shut-off valves weekly to guarantee instant sealing.

• Maintain Static Grounding: Ensure copper grounding strips and static reels maintain electrical continuity (resistance under 10 ohms).

3. Chassis & Dynamic Stress Calibration

• Torque U-Bolts: Retighten leaf spring U-bolts and saddle mounting bolts every 10,000 km to handle liquid surge stress.

• Wheel Hub & Tire Care: Repack wheel hub bearings on schedule and rotate tires every 15,000 km to counteract uneven wear from fluid movement.

• Smooth Driving Habits: Avoid abrupt braking and hard acceleration to reduce dynamic liquid sloshing against baffle plates.
