OPW Fixed Reach Style Top Loading Arm is used for fixed-position top loading of tank trucks or railcars where the vehicle is spotted at a predictable distance from the riser. Its configuration is selected around the loading geometry and transfer duty. AxFlow can help define the appropriate arrangement for a specific terminal.
The verified operating principle is that three swivel planes provide vertical and lateral movement while keeping the drop pipe vertical. This provides the movement or control needed at the loading point. Exact configuration depends on the installed piping and connection requirements.
OPW documents that OPW lists 2, 3 and 4 in sizes, carbon steel, stainless steel or aluminum construction, and flanged, threaded or all-welded configurations. These values provide a basis for screening the application. Final selection must also consider the actual medium, pressure, temperature and site geometry.
Check vehicle spotting accuracy, required reach, media, material, connection style and whether tight-fill or closed loading is required. These parameters determine the suitable arm, material and connection arrangement. AxFlow can support product selection and availability checks.
AxFlow can support service and spare-parts enquiries for OPW loading equipment. The correct parts depend on the installed configuration and revision. Supplying identification details helps confirm the appropriate components before ordering.
