A UN Portable Tank (often classified under T-Codes from T1 through T75) consists of a certified cylindrical pressure vessel mounted within an external ISO structural framework. Unlike a standard dry container or a flexibag in a box, a UN Portable Tank is designed under ASME Section VIII and IMDG Chapter 6.7 rules to transport hazardous and non-hazardous gases, liquids, and cryogenic fluids under pressures from 1.75 bar up to 34.5 bar.
They feature specialized fail-safe triple closure valves, calibrated pressure-relief assemblies, bursting discs, and thermal insulation systems engineered to survive ocean transit dynamic stresses without risk of rupture.
For highly aggressive chemicals such as Hydrochloric Acid (HCl), ferric chloride, or high-purity caustics, our T14 and specialized tank vessels are manufactured with heavy-wall carbon steel or 316L shells and subsequently lined with high-grade fluoropolymers (such as PTFE, PFA, or ECTFE) or pure rubber vulcanization.
Every square centimeter of lined inner surface undergoes mandatory non-destructive high-voltage electrostatic spark testing (up to 20,000V) to verify zero micro-porosity before clearance. Furthermore, top-discharge-only configurations eliminate vulnerable bottom hull valve penetrations entirely.
Depending on route parameters and destination terminal capabilities, we equip containers with three primary heating architectures:
1. Steam Heating Channels: Longitudinal extruded stainless channels welded to the bottom half of the tank (typically 6-12 runs offering 8-12 m² heating area) capable of handling saturated steam up to 6 bar.
2. Glycol/Water Circulation: Closed-loop circulating fluid jackets providing uniform, gentle heat distribution for temperature-critical food-grade liquids.
3. Electric Trace Heating: Thermostatically controlled, explosion-proof (ATEX / IECEx Zone 1) electric resistance cabling capable of maintaining precise transit temperatures up to 130°C across long-distance railway routes where auxiliary steam is unavailable.
Each container is delivered with an exhaustive Technical Dossier containing:
• Statutory Certificate issued by Bureau Veritas (BV), DNV GL, Lloyd’s Register (LR), or CCS affirming full compliance with IMDG, ADR, RID, USDOT, and CSC regulations.
• ASME Manufacturer’s Data Report (Form U-1) when manufactured under the ASME 'U' Stamp protocol.
• 100% Weld Radiographic Inspection (RT) and Ultrasonic Testing (UT) non-destructive reports.
• EN 10204 Type 3.1 Material Test Reports (MTR) detailing chemical analysis and mechanical tensile/impact properties for all pressure-retaining components.
• Cleanliness, Passivation, and Hydrostatic/Pneumatic Pressure Test Certificates.
Standard ISO dry boxes and proven catalog reefer/tank configurations can be supplied in single-unit sample batches or dispatched from existing yard inventory. For fully engineered OEM/ODM builds—such as specialized DNV offshore crash-frame containers or fluoropolymer-lined chemical vessels—the standard MOQ is typically 2 to 4 units to optimize automated tooling setups.
Factory production lead times typically range between 45 to 65 days from technical drawing sign-off to quay delivery at Port of Tianjin or Shanghai, substantially faster than Western European manufacturing schedules.
Our T75 cryogenic containers feature a concentric double-hull configuration consisting of an austenitic stainless steel inner vessel suspended within an outer carbon steel jacket using low thermal-conductivity composite support blocks.
The annular interstitial space is loaded with multi-layer reflective insulation (MLI) and evacuated to an ultra-high vacuum state with active chemical getters. This thermal barrier yields an exceptionally low Normal Daily Boil-Off (NER) rate of less than 0.25% to 0.35% for liquid nitrogen or LNG, providing up to 45 to 60 days of safe holding time before automated pressure relief is triggered.
