34m³ LPG Tanker Semi Trailer

Introduction

Liquefied Petroleum Gas (LPG) logistics demands the highest tier of pressure vessel engineering. ZW Group’s LPG semi-trailers are designed as high-pressure safety systems, ensuring the secure transport of propane and butane across long distances and varying environmental conditions. Our designs balance structural integrity, operational efficiency, and compliance with international standards to meet demanding B2B distribution needs.

Company Overview

ZW Group is a leading manufacturer of high-pressure LPG tanker trailers, delivering engineered solutions for bulk gas transport worldwide. We combine precision welding, controlled heat treatment, and rigorous safety inspection regimes to supply ASME-, ADR-, and DOT-compliant equipment. With established export experience to Africa, the Middle East, and global energy markets, ZW Group provides dependable production capacity, technical service, and genuine spare parts support.

Product Introduction

This LPG Tanker is manufactured using Q345R pressure vessel steel with an optimized 12mm shell thickness to meet high-pressure service requirements. The vessel fabrication uses automated submerged arc welding and controlled annealing to relieve residual stresses and preserve long-term toughness. Designed for a working envelope centered at a design pressure of 1.77 MPa, the tank construction supports reliable handling of propane and butane in pressurized bulk transport operations.

Key Features

• High-Pressure Integrity: Engineered for 1.77 MPa design pressure, with 100% X-ray weld seam verification to confirm weld quality and continuity.
• Robust Materials: Q345R pressure vessel steel delivers high tensile strength and fracture toughness for safe LPG containment.
• 12mm Shell Thickness: Optimized plate thickness for balanced weight, strength and fatigue resistance in pressurized service.
• Premium Relief & Safety Hardware: Fitted with REGO safety relief valves and remote emergency shut-off systems for controlled overpressure protection.
• Stable Suspension: Triple-axle heavy-duty suspension (3 x 13T/16T) with air suspension options for smooth, secure transport of high-density loads.
• Flexible Unloading: Configurable pneumatic or hydraulic unloading systems with vapor recovery options to reduce emissions during transfer.
• Advanced Protection: Emergency relief valves, grounding points, and an anti-rollover frame enhance on-road and emergency performance.

Technical Specifications

Applications

Designed for bulk LPG distribution, this trailer suits long-haul delivery to commercial gas stations, industrial users, residential energy hubs, and regional propane or butane depots. Its pressurized design supports efficient transfer and storage for suppliers and logistics operators requiring reliable, high-throughput transport assets.

Performance and Value

ZW Group tankers deliver durable in-service performance through controlled heat treatment and stress-relieving processes that extend fatigue life under repetitive loading. High-integrity fabrication and certified components reduce unexpected downtime and lower operational risk. For fleet managers and distributors, this translates into reduced insurance exposure, predictable maintenance cycles, and better lifecycle economics compared with lower-spec alternatives.

Quality and Support

Every unit undergoes comprehensive testing including hydraulic pressure testing at 2.1 MPa, airtightness verification, and full non-destructive evaluation of welds (X-ray). We supply operator training, maintenance documentation, and a global spare parts network, ensuring genuine REGO and Fisher replacement components are available to minimize downtime and maintain safety compliance.
