Key Technical & Certification Requirements for T21 Tank Containers
1. Design & Manufacturing Standards
Complies with IMDG CODE, ADR/RID, 49CFR, ASME BPVC Section VIII Division 1, and GB150. Third-party certification (CCS/BV/ASME U Stamp) is mandatory, with 100% radiographic inspection of welds (weld efficiency = 1.0) and stress-relief heat treatment required.
2. Safety Accessories & Testing
￮ Safety components: DN50 rupture disk, DN15、DN20、DN25、DN32 liquid ball valve, DN20 gas phase valve, Filling nitrogen.
￮ Testing requirements: Hydrostatic test (21 bar), pneumatic tightness test (14 bar); in-service inspection every 2.5 years (in addition to initial inspection).
￮ Operational protection: Maintain positive nitrogen pressure during transportation; temperature ≤ 30℃; avoid exposure to moisture and oxidizing agents.
Core Transportation & Operation Specifications
1. Labeling & Marking
￮ UN 3394: Label with Class 4.2 flammable hazard label + water-reactive subsidiary label; mark "Water prohibited for fire fighting (except as authorized by experts)".
￮ UN 3399: Label with Class 4.3 hazard label; mark water-reactive warning.
￮ Tank marking requirements: Clearly indicate T21 code, UN number, volume, design pressure, and manufacturing date.
2. Loading & Unloading Operations
￮ Conduct the entire process under nitrogen protection to prevent contact with air and water.
￮ Loading/unloading areas must be free of ignition sources; equipped with dry sand, inert powder, emergency eyewash stations, and safety showers.
￮ Leakage response: Cover spills with dry sand immediately; do NOT flush with water.
3. Transport Restrictions
￮ Limited quantity: 0; Exceptional quantity: E0.
￮ Transportation category: V1; dedicated vehicles only; no mixed loading with other dangerous goods.
￮ Packaging specification compliance: Meet Special Provision PP86 and Packaging Instruction P400.
Key Notes & Common Issues
1. UN 3394 vs UN 3399
￮ UN 3394 is pyrophoric (ignites spontaneously on air exposure), while UN 3399 is non-pyrophoric. Both are water-reactive and share T21 tank compatibility, with differences only in labeling and emergency response procedures.
2. Material Selection for Low-Temperature Conditions
Prioritize 09MnNiDR ,16MnDR，SS304 、SS316 for low-temperature applications; use SA-516 for ambient-temperature scenarios to ensure corrosion resistance and low-temperature toughness.
3. Emergency Response Protocols
￮ For leaks: Cover with dry sand or inert powder to prevent spread; do NOT use water for dilution or flushing.
￮ For skin contact: Blot the affected area with dry sand or inert powder first, then wipe with ethanol, rinse thoroughly with water, and seek medical attention immediately.
￮ Personal protective equipment (PPE): Full-body flame-retardant clothing, chemical-resistant gloves, safety goggles, and face shields are mandatory for all operators.
