Pressurized in large LPG storage vessels, tanks, cylinders, and gas bottles, LPG can be in the form of either liquid or vapor/gas. Today’s existing propane delivery methods are determined by the form in which it is being transported. More often than not, a compact liquid state is preferable for transportation.
Shipment methods can include local gas reticulation systems pipelines, cylinder trucks, intermodal tanks, tanker trucks, rail, and ship. Let’s take a look at these transport systems.
Cylinder Trucks
For the delivery of exchangeable gas bottles, this usually applies to low volume users, the trucks being used resemble smaller flatbed style trucks. The bottles are picked up, refilled, and delivered with these trucks.
Bobtail Tankers
Bobtail tankers are used with deliveries that are relatively local. No trailer is involved because the tankers are not articulated – unlike road tankers. This truck may also be referred to as a rigid tanker and comes in a 10 ton version all the way down to a four ton version. A hose reel and pump are used for gas disbursement.
Road Tankers
B-doubles and large road tankers are used to move LPG in larger quantities between depots and terminals. Occasionally used are the three trailer type LPG “road trains”. Between 19 and 23 tons could be held by a single road tanker. Two large tank trailers (linked by a fifth wheel) are pulled by a prime mover for the LPG B-double transport mode.
Reticulated Systems
LPG reticulation systems are used by some building estates and communities. In this case, from central tanks or storage tanks, LPG is delivered through pipes to the homes which are equipped with a meter to measure LPG usage.
Pipeline
This delivery system is rare because of the prohibitive expense. Between storage terminals and gas fields, LPG pipelines are typically used.
ISO Tanks and Vault Transported by Rail
To move large, multiple quantities of LPG, tanker railcars are used. Their capacity can range from as much as 27,000 L, down to as little as 65,000 L. At roughly 5m high and 19m long, they hold approximately 65 tons of LPG.
ISO Tank Containers – Intermodal
Mounted within a standardized framework, this LPG storage vessel is referred to as an ISO Tank Container. (ISO stands for International Organization for Standardization). A typical size for an LPG ISO tank (though different sizes exist) is 2.55m high, 2.4m wide, and 6.05m long. That’s about 20 feet in length.
Over Water – By Ship
Gas carriers (or large tankers) are capable of transporting LPG across entire oceans. Carrying approximately 43,000 tons, VLGC class ships (very large gas carriers) can measure as long as 230m. Around the world, currently in service, there are approximately 200 VLGCs.
Mickey Genuine Parts may not carry tankers, but we carry many useful trailers including refers, party trailers, beverage trailers, bulk trailers, and more. For the frugally minded individual trying to save a buck or two, we even offer used trailers in great condition.
