LPG tank trailers occupy a unique niche in the transportation industry. Unlike conventional liquid tankers, these trailers are purpose-built to haul pressurized gases including propane, butane, and anhydrous ammonia. The specialized nature of this cargo means that every LPG tank trailer must meet strict design and materials standards. Due to the exceptional build quality, the used market a great place to find durable equipment at a reduced cost.
The defining certification for this equipment class is the MC 331 standard. The standard requires that tankers are built to handle the unique demands of pressurized gas transport, from the materials used in construction to the distinctive rounded-end barrel design that manages the stress of pressurized cargo. White paint is also a standard feature across these trailers, minimizing heat absorption and reducing pressure buildup during transport. Stainless steel construction gives these trailers exceptional longevity, and many used units have decades of service life remaining when properly maintained.
