Semi Trailer Tank

Semi Trailer Tankers for Fuel, Chemical, Food-Grade and Bulk Transport

 

Precision-engineered tank semi-trailers configured for liquid fuel, hazardous chemicals, food-grade payload, and dry bulk materials. Built to DOT, ADR, and ASME standards, our tankers optimize payload-to-weight ratios through automated longitudinal plasma welding, robotic seam joining, and stress-relieved vessel designs.

Operational Applications

Fuel Station Logistics: Multi-compartment delivery of mixed fuel grades in a single haul with automated API bottom-loading systems.

 

Chemical Process Logistics: Transport of hazardous chemicals including sulfuric acid, caustic soda, and industrial solvents under class-specific temperature control.

 

Dairy and Food Processing: Temperature-controlled bulk milk or liquid oil transit maintaining temperature change under 1 deg C per 24 hours.

 

Infrastructure and Construction: High-speed pneumatic discharge of bulk cement directly into concrete batching plant silos.

 

Engineering and Customization Options
 

Compartment Layout

 

Customized partition ratios with individual dished heads, spillboxes, and bottom discharge valves per section.

Heating Systems

 

External steam heating channels, thermal oil circulation coils, or electric resistance heating elements for temperature-sensitive cargoes like bitumen or paraffin.

Running Gear and Axle Configurations

Steerable axles, liftable front/rear axles, and specialized air suspension setups for tight turning radiuses or local axle-weight regulations (such as US Bridge Formula or European 40t limits).

Metering and Pumping Equipment

 

PTO-driven gear pumps, hydraulic vane pumps, digital flow meters with printer units, and wireless level monitoring integrations.

 

Quality Control and Compliance Standards

 

1

Robotic Submerged Arc Welding (SAW)

Longitudinal and circumferential seams are welded using automated double-sided submerged arc equipment to prevent fatigue cracking.

2

100 Percent Non-Destructive Testing (NDT)

All pressure-bearing vessel welds undergo 100 percent Radiographic Testing (RT) and Ultrasonic Testing (UT) before hydro-testing.

3

Hydrostatic and Pneumatic Testing

 

Each tank shell is subjected to hydrostatic pressure testing at 1.5 times design pressure for a minimum 30-minute hold time.

4

Manufacturing Certifications

 

Manufactured under ISO 9001:2015 quality frameworks, compliant with ASME Section VIII Div 1, ADR road transport agreements, and DOT 406/407 specifications.

FAQ

 

Q: What materials are used to prevent structural stress cracking on low-weight aluminum tankers?

A: We use high-tensile 5454-H32 aluminum alloy for the vessel shell and dished heads, combined with continuous robotic longitudinal seam welding. The subframe uses stress-relieved extruded crossmembers. All internal baffles are hydro-formed with flanged edges to distribute dynamic surge forces evenly during braking and cornering.

Q: Can you configure tankers to comply with local axle-load and length regulations in North America or Europe?

A: Yes. Wheelbases, axle spacing, kingpin locations, and overall length are engineered specifically to comply with the target region's transport laws—such as the US Federal Bridge Gross Weight Formula or European Directive 96/53/EC. Detailed axle load calculations are provided during the design approval phase.

Q: How do you prevent cross-contamination in multi-compartment fuel tankers?

A: Each compartment is isolated by double-dismantled dished bulkheads with a sealed void space between them. Every section operates as a self-contained unit with its own API discharge valve, vapor recovery vent, pneumatic emergency shut-off valve, and optical overfill prevention probe.

Q: What quality documentation is included with the tanker shipment?

A: Every unit ships with a complete Quality Assurance File containing:
Mill Test Reports (MTR) for shell plates and structural steel.
100 percent NDT Radiographic Inspection Reports.
Hydrostatic and Leakage Test Certificates.
Tank Calibration (Ullage) Chart.
Commercial Vehicle Certificate of Conformity (CoC).

Q: What pump and metering systems can be integrated into the trailer subframe?

A: We integrate hydraulic-driven or PTO-driven pumps (such as Blackmer vane pumps, Roper gear pumps, or stainless steel sanitary pumps) along with LC (Liquid Controls) or Total Control Systems (TCS) positive displacement meters with air eliminators and register printers directly in the side toolboxes.

Q: How do I request an accurate price quote and technical drawing?

A: To receive a formal quotation and approval drawing within 24 hours, contact our technical sales team with your transport medium (density and viscosity), required tank capacity, axle configuration, target port of discharge, and any regional regulatory requirements (ADR, DOT, or ASME).
