Tanker baffles are angled barriers installed in mobile storage tanks used to cut down on the amount of sloshing and movement of transported liquid. Used in Tanker trucks and Tanker Ships.
The movement of the heavy liquid inside an oil tanker truck or tanker ship can be a problem as it moves fore and aft and laterally during vehicle turns and going up or downhill. Shifting weight can create control problems for drivers of trucks. Shifting weights in tanker ships can cause listing that will slow the delivery time.
The oil in a tanker truck is a heavy load and when it starts to move it can create control problems. Tanker Baffles create containment and sloshing reduction solutions for shifting weights.
A tanker without baffles where there’s just one liquid product handles differently than any other trailer. There is nothing inside the tank to slow down the flow of the liquid. Therefore, the forward-and-back surge inertia is very strong. Non-baffled tank trucks usually transport food products (e.g., milk).
Tank Baffles are installed bulkheads that segment the holding tank so the fluid weight is distributed to each segment. The oil travels through a hole in the baffle but the walls prevent the total load from moving drastically. Sloshing still occurs but it is contained to the spaces between the baffles.
Slosh dynamics is a science unto itself, that takes into consideration the inertia of moving bodies (oil in a tank) these are called inertial waves. The control of inertial waves is what baffles are installed to do.
Most of the time, tanker trucks are carrying dangerous liquid contents such as gasoline and fuel oils; therefore the stability of partially-filled liquid cargo vehicles is very important. For safer transporting of bulk liquids, baffles help distribute and control the shifting weight in road tankers. Avoiding jack-knife situations and overturning due to uncontrollable weight is the goal for baffled tank trucks.
Fuel transport safety is a major concern that any company that moves and distributes fuel is concerned with. Various cargos require different types of tankers to safely get the cargo over the road within the Department Of Transportation requirements. Fuel depots, chemical transport companies and gas transport companies need safe and reliable tankers to hold that material. See index of truck tank types
