WSI range of Top loading arms are specifically engineered to handle the unique nature of liquid compressed gasses and vapors transported in tank trucks or railcars, or trans-loaded between the two.
Up to #300 rated with minimal flanged connections in carbon steel and stainless steel to handle refined products such as LPG, Propane, Butane, Isobutene, Anhydrous Ammonia, LNG as well as course unrefined NGL’s.
Typical size is 2” but larger 3” and 4” are available for specialist applications. For longer reach applications a 3” arm is usually better suited for structural strength with a 2” connection point to the tank truck or railcar.
Connection devises will vary with different applications. Each WSI compressed gas loading/unloading arm is designed to work with either, dry-gas couplers and adapters, hammer unions or lap flange connection points. Outboard swivel joints are incorporated in to each loading arm with multiple flow control and connection options. Isolation valves, breakaway devices and remote shut down devices can all be incorporated in to each configuration of top or bottom, loading or unloading arm.
