Product Overview
Our Railway Flexitank is engineered specifically for bulk liquid transportation by rail, meeting the stringent safety and performance requirements of railway container transport. Built for 20ft standard railway containers, it provides a safe and economical solution for long-distance bulk liquid shipment via rail.
Compared to traditional rail tank cars, railway flexitanks utilize standard dry containers, making them much more flexible and cost-effective. They can be easily integrated into intermodal logistics chains – from factory to truck to rail to final destination – without transloading the liquid cargo.
Widely used on routes such as China-Europe freight trains, Central Asia rail lines, and domestic long-haul rail transport. Ideal for bulk commodities where rail offers significant cost and capacity advantages over road transport.
Core Advantages
🚆 Rail-Specific Safety Engineering
– Reinforced structure designed for railway vibration and impact forces
– Extra strong seams withstand long-haul rail stress and buffing
– Enhanced baffle system prevents cargo shift during transit
– Reinforced steel pipe frame and stronger end bulkheads
– Multiple safety layers and pressure management systems
– Designed to meet railway transport impact test standards
💰 Significant Cost Advantage
– Uses standard dry containers – no need for specialized tank cars
– Much lower packaging cost per liter vs tank car transport
– No demurrage charges, no return freight for empty tanks
– Better cost efficiency for long-distance bulk shipments
– High volume per container maximizes rail economics
🔄 Seamless Multimodal Integration
– Works in sea-rail, truck-rail and combined transport chains
– No need to transload liquid between different transport modes
– Door-to-door delivery in standard containers
– Reduces product handling and contamination risk
– Compatible with standard container logistics infrastructure
📦 Large Capacity, High Efficiency
– Optimized for 20ft dry containers (railway standard)
– Maximizes volume utilization of container space
– Up to 24,000L-26,000L per 20ft unit (depending on cargo density)
– Efficient loading/unloading with standard pump equipment
– Standard container handling at rail terminals
