WSI range of Top and Bottom loading/unloading arms is 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.

The variety of loading and unloading challenges are greatest in the chemical and industrial products industry. WSI’s range of Top and Bottom Loading/Unloading arms is specifically engineered to handle the exact nature of each chemical or industrial liquid or vapor being handled in and out of tank trucks, rail cars and ISO container tanks. Whether loading or unloading tar sands, acetones, molten sulfur or acids, WSI has a specific solution to handle each application safely and successfully… Standard top and bottom loading arm configurations are often used for chemical and industrial products; however, all products require specialist knowledge and equipment for a safe, efficient transfer. Each WSI chemical and industrial loading/unloading arm is specifically engineered to match the exact nature of the product being handled. These are not petroleum loading arms with different elastomers…
