20ft Multi-Compartment Non-Standard Tank Container

Product Introduction

The multi-compartment non-standard tank container is a dedicated tank container whose 20ft or non-standard tank body is internally divided by partition plates into multiple independent compartments. Each compartment has its own loading/unloading connections, safety relief valves, level gauges, pressure gauges and necessary piping systems, enabling simultaneous transport of different liquids or different batches of the same liquid — achieving “one tank, multiple uses, multi-product co-transport.”

This product is mainly designed for multi-product small-batch transport scenarios, such as fine chemical distribution, lubricant product series delivery, food-grade raw material multi-product supply, and combined transport of solvents and additives. Compared with single-compartment tank containers, the multi-compartment design greatly reduces the number of tanks required and transport trips, lowering logistics costs and improving vehicle and vessel loading efficiency.

The number of compartments, volume allocation per compartment, tank material, design pressure, temperature control, insulation/heating, valve brands and piping layout can all be customized to customer requirements. The product complies with ISO, CSC, ADR/RID, IMDG and other international standards, meeting global multimodal transport requirements. Food-grade, high-purity and corrosion-resistant designs are also available according to the media to be carried.

Product Features

1.Independent multi-compartment design: The tank body is divided by full-penetration welded partition plates into 2–6 independent compartments, each equipped with its own loading/unloading valves, safety relief valve, level gauge and pressure gauge, without mutual interference.

2.Multi-product co-transport reduces cost and improves efficiency: One tank container can carry multiple different liquids or different batches of the same liquid, reducing empty-tank repositioning and tank procurement, significantly lowering transport costs.

3.Cross-contamination prevention: Compartments are completely isolated by full-penetration welded partition plates, and piping is independently arranged for each compartment, effectively preventing cross-contamination between different media.

4.Flexible volume allocation: The volume of each compartment can be flexibly designed according to customer loading requirements, e.g., 10,000L + 10,000L, 8,000L + 8,000L + 8,000L, 12,000L + 6,000L + 6,000L, etc., meeting different batch size needs.

5.Strong non-standard customization: Number of compartments, partition positions, tank material, lining, insulation/heating, valve brands, paint color and loading/unloading methods can all be customized.

Independent safety protection: Each compartment has independently installed safety relief valve, pressure gauge and level gauge, so abnormal conditions in one compartment will not affect the normal operation of others.

6.Efficient cleaning and maintenance: Each compartment can be independently cleaned, purged and inspected without emptying the whole tank, reducing downtime.

7.Global compliant delivery: CSC, ASME U, ADR/TPED, IMDG and other certifications are available, with BV, SGS or other third-party inspection supported for global delivery.

Product Advantages

1.Designed for multi-product small-batch logistics
Traditional single-compartment tank containers require multiple tanks or trips to transport multiple liquids, resulting in low efficiency and high cost. The multi-compartment non-standard tank container consolidates multiple products into one tank, especially suitable for chemical traders, lubricant distributors, fine chemical manufacturers and food ingredient suppliers.

2.High-precision partition manufacturing process
Partition plates are welded with full penetration, and critical welds undergo 100% NDT (RT/UT/MT/PT). Compartment-by-compartment hydrostatic tests, air tightness tests and helium leak tests ensure independent sealing and eliminate internal leakage.

3.Reduced carbon emissions, aligned with green logistics trends
Multi-compartment co-transport reduces transport vehicles, vessel voyages and empty-tank repositioning, lowering carbon emissions per unit of product and supporting corporate sustainability goals.

4.High utilization and fast turnover
One multi-compartment tank container can replace the transport capacity of 2–4 single-compartment tanks, reducing total fleet size and yard occupation while improving asset turnover.

5.Full life-cycle technical support
We provide general arrangement drawings, partition layout drawings, strength calculation reports, operation manuals, cleaning procedures, spare parts lists and maintenance guidance, with global parts supply support.

6.Diverse material and lining options
Tank materials include Q345R carbon steel, S30408, S31603, duplex stainless steel, etc. PTFE lining, phenolic epoxy lining or polished finishes are available according to media characteristics, meeting food-grade, high-purity and highly corrosive service conditions.

Precautions

1.Media compatibility confirmation: Media loaded in each compartment must be compatible with tank material, seals, lining and piping materials. If different media are loaded in different compartments, chemical compatibility evaluation must be conducted in advance.

2.No incompatible media in adjacent compartments: Never load media that may react violently, contaminate each other or create hazards in adjacent compartments, such as acids and alkalis, oxidizers and flammables.

3.Independent filling management per compartment: Each compartment must be filled separately according to its rated volume and maximum filling ratio. Overfilling is prohibited. Before filling, verify compartment number and corresponding medium to avoid loading mistakes.

4.Independent seal inspection per compartment: Before each loading, check valves, flanges and seals of each compartment to ensure no leakage and no cross-compartment communication before loading.

5.Independent relief valve setting: The set pressure of each compartment’s relief valve must be set according to the vapor pressure and design pressure of the medium in that compartment. Never interchange or mix them.

6.Cleaning and purging: Before media change or compartment maintenance, each compartment must be individually drained, cleaned, purged and tested for oxygen content, dew point and residues. Each compartment should be purged independently to prevent cross-contamination.

7.Static grounding: Reliable grounding is required during loading and unloading. Use explosion-proof tools and prohibit non-explosion-proof electrical equipment in the operation area.

8.Periodic partition weld inspection: Multi-compartment tank partition plates are full-penetration welded. Regular internal inspection and NDT should be performed to confirm no cracks, corrosion penetration or cross-compartment leakage.

9.Prevent local overheating: For multi-compartment tanks with heating devices, heating should be uniform to avoid excessive thermal stress on partition plates or tank body from local overheating.

10.Clear marking: Loading/unloading connections, valves and instruments of each compartment should have clear numbering and medium identification to prevent operator errors.

11.Pre-transport confirmation: Before transport, confirm that media in all compartments comply with IMDG/ADR and other transport regulations, and verify filling quantity, pressure and temperature of each compartment are normal.

12.Emergency response: In case of leakage, immediately close the valves and piping of the affected compartment, evacuate personnel upwind, and handle according to the SDS of the corresponding medium.
