3-Axle LPG Tanker Semi Trailers for Liquid Petroleum Gas Transportation

WONDEE 3-axle LPG tanker semi trailers provide safe and efficient transportation of liquid petroleum gas. With over 20 years of experience since 1999, WONDEE combines advanced production processes, quality materials, and engineering expertise to deliver reliable semi-trailers for industrial logistics worldwide.

Understanding LPG Semi Trailers and Their Applications

A semi-trailer has axles located behind the vehicle’s center of gravity and uses a king pin to transfer load forces to the tractor. It carries no power itself and relies entirely on the tractor for movement. LPG semi trailers are specialized to transport highly flammable liquid petroleum gas safely over long distances.

These trailers are essential in fuel distribution networks, chemical plants, and industrial sites requiring bulk LPG delivery. Their design ensures secure containment, pressure stability, and compliance with global safety standards. Applications include energy supply logistics, gas stations, and petrochemical transport.

Key Components and Technical Advantages

The chassis uses high-strength Q345B main beams and Q235 support beams, offering durability while reducing weight. The tank is made of Q370R steel (11mm body, 13mm end socket), designed with local stress analysis to maximize strength and minimize curb weight.

Suspension systems feature 3×13-ton FUWA axles with air suspension and double tires, providing excellent stability and even load distribution. Wheels use TRIANGLE 12R22.5 or steel 9.00x22.5, supporting long-distance transport with minimal maintenance.

Transportation Performance and Operational Benefits

The trailer’s total weight is 40,000 KGS with a curb weight of 14,913 KGS and a rated load of 25,087 KGS. Its 3-axle design ensures stable handling and reduced rollover risks. The fifth wheel load reaches 15,600 KGS, optimizing tractor performance and fuel efficiency.

LPG pipelines and emergency valves allow fast loading and unloading while maintaining safety. The trailer integrates static grounding, remote cut-off systems, fusible plugs, and safety valves to prevent overpressure or fire hazards during transport. Dry powder fire extinguishers enhance onboard safety.

Quality Assurance and Production Standards

WONDEE implements ISO 9001-2015 certification for both production and services. Over 80% of parts are self-manufactured, allowing full control over material quality and assembly precision. Each semi trailer undergoes 100% inspection, and the chassis comes with a 24-month warranty.

Steel plates undergo elemental analysis and mechanical property testing before production. Each unit is water pressure tested, and plasma welding ensures seam integrity. Painting includes shot blasting and nappe-type spray with natural gas-based coatings, ensuring corrosion resistance and a glossy finish.

Technical Specifications of LPG Tanker Semi Trailer

Series, Applications, and Customization Options

WONDEE semi trailers include flatbed, lowbed, fence, oil tank, LPG tank, bulk cement, and car transport series. Customers can choose axle number (2–4), suspension types, colors, and optional OEM or ODM customizations. These options ensure trailers meet specific operational requirements.

LPG tankers are ideal for industrial energy logistics, gas stations, and petrochemical distribution. Safety devices, valve systems, and robust chassis design enhance efficiency, reduce maintenance, and ensure compliance with international transport regulations.
