The slide sleeve type loading arm incorporates a slide-sleeve assembly that telescopes in and out to adjust for variations in the distance from the loading rack to the tank truck. It is used primarily in small bulk plants and terminals for top loading fuel oil or other petroleum products. This cost-effective loading arm is time-tested as a practical method of locating the drop tube accurately and easily.
The slide sleeve is a medium-duty unit designed for flow rates up to 15 ft/sec (4.5m/sec.). Higher flow rates may tend to push the inner tube out beyond the loading point.
