Freight Class for Pressure Vessel
To estimate your shipment, use the Pressure Vessel Freight Class Calculator.
The Pressure Vessel Freight Class Examples use the current 13-tier density scale, effective July 19, 2025, and range from Class 65 to 100.
These are density-based estimates.

Pressure Vessel shipment comparison
Pressure Vessel Freight Class by Shipment Format
Pressure Vessel freight class can change with the vessel diameter and length, support frame or saddles, nozzles, protective clearance, and top-load restrictions. Use the finished packaged dimensions and total weight rather than the equipment's unpackaged size.
| Pressure Vessel shipment | Typical packaging | Density tendency | Stackability | Planning note |
|---|---|---|---|---|
| Compact pressure vessel | Reinforced pallet or skid with blocking, restraint, and weather protection | Medium to higher | Limited | Dense vessel secured on saddles or a reinforced skid; this example calculates to 25.00 lb/cu ft and Class 65. |
| Skidded pressure vessel | Framed crate with internal restraint and protection for controls and moving parts | Medium to higher | Possible with engineered crate | Vessel, nozzles, instruments, and supports protected; this example calculates to 18.33 lb/cu ft and Class 70. |
| Large pressure vessel | Elongated or oversized crate with structural bracing and protective clearance | Medium to lower | Usually non-stackable | Long vessel with nozzle clearance and rigging points; this example calculates to 8.50 lb/cu ft and Class 100. |
| Vessel with drive, fittings, and support frame | Main vessel or tank plus separately protected agitator parts, instruments, valves, legs, and controls | Varies | Usually limited | Large empty vessels can occupy substantial cubic space even when their packaged weight is moderate. |
Pressure Vessel shipping options
Choosing a Shipping Method for Pressure Vessel
The appropriate service depends on finished dimensions, packaged weight, piece count, loading method, value, stackability, and whether specialized handling is required.
| Pressure Vessel shipment | Common shipping option |
|---|---|
| Compact pressure vessel | Standard LTL with packaging and handling review |
| Skidded pressure vessel | LTL or volume service with weight and handling review |
| Large pressure vessel | LTL or volume service with weight and handling review |
| Vessel with drive, fittings, and support frame | LTL, volume, partial truckload, or dedicated service after piece-count and handling review |
Heavy, long, high-value, non-stackable, multi-piece, or rigging-dependent pressure vessel shipments may need carrier review before booking.
Pressure Vessel Packaging, Stackability, and Damage Risk
Pressure Vessel Packaging
- Support the vessel, mixer, or shaft on engineered saddles, frames, or skids that prevent rolling and point loading.
- Cap nozzles, ports, manways, instruments, and fittings and brace long shafts or projecting drives.
- Protect shells, linings, coatings, nameplates, load cells, controls, and polished product-contact surfaces.
Pressure Vessel Stackability
- Treat round vessels, tall tanks, open frames, and projecting nozzles as non-stackable.
- Use structural framing rather than the shell or vessel roof to carry any load above the shipment.
- Mark sling points, center of gravity, upright orientation, and areas where forks must not enter.
Pressure Vessel Fragility and Liability
- Prevent rolling, shell distortion, nozzle damage, coating abrasion, and movement of internal components.
- Drain or secure approved contents and document cleaning or contamination-control requirements.
- Confirm declared value and specialized handling for pressure-rated, lined, polished, or custom-fabricated equipment.
Before Requesting a Pressure Vessel Freight Quote
How to Measure a Packaged Pressure Vessel Shipment
- Measure after the pressure vessel is secured and all pallet, skid, crate, framing, guards, and protective materials are complete.
- Include runners, saddles, legs, controls, fittings, attachments, overhang, and every projecting packaged component.
- Measure to the longest, widest, and tallest finished point and use the total tendered shipment weight.
Pressure Vessel Freight Quote Checklist
- Record the finished packaged length, width, height, and total weight.
- State whether the shipment is stackable and whether top loading is prohibited.
- Include photos showing packaging, securement, labels, lift points, and exposed risk areas when practical.
- List detached controls, guards, accessories, tooling, fittings, and other separate pieces.
- Confirm forklift, dock, crane, rigging, liftgate, or specialized loading requirements.
