Tank Truck Types: Fuel, Water, Chemical and LPG

A tank truck - also searched as a tanker truck, tanker lorry or road tanker - is specified by the medium it carries, not by the chassis. The same ISUZU, DONGFENG, SINOTRUK HOWO or SHACMAN carrier can take a fuel tank, a potable-water tank or a chemical pressure vessel, so the body specification is where the engineering and the cost sit.

• Fuel and oil tank trucks. Diesel, gasoline, kerosene and jet fuel service, normally 5,000-30,000 L with two to six compartments, API or gear pump, totalizing flow meter, vapor recovery, bottom loading and overfill protection.
• Water tank trucks. Potable water uses 304 stainless steel or an epoxy-lined carbon-steel tank with food-grade fittings; construction water uses a heavier carbon-steel shell with a rear spray bar and high-pressure jets.
• Water sprinkler trucks. 8,000-20,000 L with front, side and rear spray, a water cannon and a PTO pump for dust suppression, street washing and concrete curing.
• Chemical tank trucks. 316L stainless steel or rubber-lined carbon steel matched to the acid, alkali or solvent concentration, with safety valves, emergency shut-off and secondary containment where required.
• LPG and gas tankers. Pressure vessels from 5,000 to 25,000 L with approved heads, pumps, meters, safety valves and grounding, built to the pressure class your market requires.
• Milk and edible-oil tankers. 304 stainless steel, insulated shell, CIP cleaning connections and food-grade manholes for dairy and beverage collection.

Compartment count is the specification buyers most often get wrong. Two to six compartments with individual manholes, ball valves and bottom outlets let one truck deliver several fuel grades or water plus fuel on a single route. Internally, every compartment needs baffles welded to reduce surge, and the tank needs a vent, overflow, drain at the lowest point, ladder and lockable manhole.

How to Specify a Tank Truck

Start from the duty cycle, then size the tank. The eight inputs below are enough for CLW to return a line-item quotation:

1. Medium and density. Fuel grade, water quality, chemical concentration, food grade or LPG pressure class.
2. Volume per trip and trips per shift. Daily volume sets tank size more accurately than vehicle size.
3. Compartment layout. Number of products delivered per route and the volume of each.
4. Pump and metering. Flow in L/min, head, drive type (PTO, gearbox or engine), meter accuracy and nozzle set.
5. Tank material and thickness. Carbon steel, 304 or 316 stainless, aluminum or lined steel, plus baffle and shell thickness.
6. Chassis and axles. 4x2 for city distribution, 6x4 or 8x4 for depot and highway work, with legal axle and bridge limits for your routes.
7. Safety and regulatory package. Grounding, emergency shut-off, fire extinguisher, placards and the certification your country requires.
8. Destination and registration. Left- or right-hand drive, port of discharge and the homologation documents your registration authority accepts.

Send the answers with your destination port and we will confirm tank drawing, pump curve, compartment volumes and a priced component list before deposit.

The bands below are factory-direct, FOB China, for standard specifications. They are a budget framework, not a quotation; chassis brand, tank material, pump package, compartment count, right-hand drive and freight move the number.

• 4x2 water tanker, 5-8 m3: roughly USD 22,000-32,000
• 4x2 fuel tanker, 8-12 m3: roughly USD 30,000-45,000
• 6x4 fuel tanker, 20,000 L with API pump and meter: roughly USD 48,000-65,000
• 6x4 water or chemical tanker, 25-30 m3: roughly USD 55,000-80,000
• LPG pressure-vessel tanker: roughly USD 60,000-95,000

Two comparison traps are common. First, a carbon-steel tank and a 304 stainless tank are quoted as if they were the same product; they are not. Second, pump flow is left unspecified, so a 20 m3/h pump and a 60 m3/h pump look identical on paper. Ask every supplier for the same priced line items - shell material and thickness, pump model and flow, meter, valves, spray bar, paint system - then compare.

Export, Registration and Delivery

CLW builds to MIIT catalog requirements in an ISO-certified factory. Export shipments leave with certificate of origin, commercial invoice, packing list, bill of lading, tank leak and pressure-test records and pump or meter test data on request. For fuel, chemical and LPG units we also prepare material certificates and the dangerous-goods documents the carrier requires.

Lead time is typically 20-35 working days for a standard water or fuel tanker after drawing approval and deposit, and 30-50 working days for LPG, chemical or multi-compartment builds. Small 4x2 units can ship in a 40FT container or on a flat rack; 6x4 and 8x4 tankers normally move by RoRo. We supply lifting points, blocking instructions and loading photos before departure, and can prepare right-hand-drive and local homologation packages where your market allows them.

Tank Truck Safety and Maintenance

Tank trucks fail inspections on fittings, not on shells. The items that matter are the emergency shut-off valve, pressure and vacuum relief, grounding strap and anti-static provision, fire extinguisher and the condition of the baffles. A tank that has carried fuel must be gas-freed before welding or inspection, and the meter and pump seals should be checked against the maintenance schedule rather than replaced after a leak.

For daily operation, keep the manhole gasket clean, drain the lowest point after washing, inspect the vent and overflow, and record compartment volumes at each fill. Annual inspection should cover shell thickness, weld condition, valve function, grounding continuity and, for pressure vessels, the statutory pressure test. CLW supplies spare-parts kits, seal sets and the original tank drawing with every truck so your workshop can service the unit without guesswork.
