Detailed Description

ZW Group’s tri-axle LPG Tank Semi-Trailer delivers a robust, regulation-compliant platform for transporting liquefied petroleum gas. Built from high-strength HSLA steel and certified to ASME standards, this LPG Tank Semi-Trailer balances payload efficiency with rigorous safety controls. It is engineered for operators who require dependable long-haul performance and consistent uptime.

Core Construction and Quality Assurance

The pressure vessel is made of high-strength carbon steel and fatigue resistance under cyclic loads. Welding processes include submerged arc welding and robotic welding to ensure uniform seam integrity; every critical weld is verified by non-destructive testing (NDT). The tri-axle chassis is designed for balanced load distribution, with each axle rated at 13 tons to support heavy payloads while maintaining stability on varied routes.

Safety Systems and Instrumentation

Safety is embedded across the trailer: double safety valves limit overpressure events, an emergency cut-off isolates flow in hazardous situations, and an anti-rollover framework reduces the risk during evasive maneuvers. High-precision level gauges and thermometers provide accurate, real-time monitoring of tank conditions, supporting safe loading, transit, and unloading. An anti-static grounding system is fitted to dissipate static charge during fuel handling.

• Optimized volume options from 45,000 to 60,000 liters allow operators to match payload needs to route constraints and market demand while maximizing efficiency.

• Air suspension combined with shock absorbers minimizes cargo stress and improves ride comfort, reducing wear on both the vehicle and infrastructure-sensitive loads.

Applications 

This semi-trailer is purpose-built for companies transporting LPG cylinders, bulk liquefied gas to distribution terminals, and industrial clients requiring reliable tanker services. Typical users include gas distributors, petroleum logistics companies, and large industrial plants that operate regional delivery networks. It is particularly suitable for markets where certified pressure vessels and documented safety systems are required for liability and insurance reasons.

Customization

ZW Group offers configurable options to meet regional regulatory nuances and customer-specific operational needs. Customizable items include tank volume within the stated range, valve and manifold layouts, instrumentation packages, and chassis details. Backed by a global support network, ZW provides spare parts availability and technical assistance to minimize downtime. Delivery lead times typically range from 20 to 30 days, with a production capacity capable of supporting up to 300 sets per month.
