Product and service offerings

Loading Arms

Loading arms are used to provide a fast, easy and environmentally safe connection between a storage tank and mobile transport such as tank trucks, rail wagons, containers, IBC’s, river barges, etc.
  • Loading or unloading through the opening at the top of the container.
  • Fixed range for less frequently used small tank terminals, precise positioning of single compartment (small) vehicles.
  • Variable reach (“scissor” design) for medium-sized tank terminals with medium frequency of use, flexible positioning of small single-compartment vehicles.
  • Long range for large tank installations with high frequency of use, flexible positioning of multi-compartment vehicles.
WSI’s range of gas loading arms are specifically designed to handle liquefied gases such as LNG (Liquefied Natural Gas) and LPG (Liquefied Petroleum Gas). For both top and bottom piping, WSI has a loading/unloading arm for road tankers and rail tankers (Russian market) that specifically fits each application.

All gas loading arms are modularly designed with connection flanges on major components, thereby allowing for easier configuration and improved maintenance capabilities. The inlet flange of our LNG and LPG loading arms will be tailored to the application.
In the chemical and industrial sectors the variety of challenges for loading and unloading materials are diverse and complex. The range of loading arms for the chemical sector has a specific engineering work to fit with the nature of each product, liquid or gas, being managed from or to tank trucks, railway tanks or ISO containers. Whether loading or unloading tar sands, acetone, molten sulfur or acids, WSI loading arms are designed to handle each application safely and successfully.

Our loading arms, both in upper and lower connections, are offered with a standard configuration for loading or unloading different chemical and industrial products. For example, some aggressive chemical products require specialized knowledge and equipment for the safety and efficiency in the transfer of these products. Each WSI chemical loading arm has its own specific engineering work to fit the nature of the product to be handled.
The variety of difficulties that occur in loading and unloading are greater in the chemical and industrial products industry. Many products such as liquid sulfur, bitumen, and some crude oil derivatives require specific treatment at elevated temperatures during the transfer process. In extremely cold climates, heated arms are used to prevent the product from solidifying. For this reason, all WSI loading/unloading arms have their heated model.

Available with

  • Jacketed with external steam or oil.
  • Electric heating.
  • Contra Tracing.
All arms come with custom insulation sleeves to reduce heat/energy loss. The insulation sleeves are removable for inspection/maintenance. Insulation by aluminum cladding is also available. WSI’s range of heated Upper and Lower Loading/Unloading arms are specifically designed to work with the exact nature of each liquid or vapor, for both the interior and exterior of tank trucks, rail cars and ISO containers. For all liquids and vapors that depend on their temperature WSI has a specific solution to handle each application safely and satisfactorily.
WSI’s range of aircraft refueling arms are designed specifically for the fluids of the aviation industry. Whether it is for the tank terminal where jet fuel is received, stored or distributed, whether on the apron or the aircraft or helicopter that needs to be refuelled, we have the right solution available for civil and military applications.
