Chemical Top Loading Arm
The chemical and industrial products industry faces various critical loading and unloading challenges. WSI’s range of Truck loading arm / Tanker loading arm 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 top loading of tar sands, acetones, molten sulphur or acids, WSI has a specific solution to handle each application safely and successfully.
Standard tanker and truck top loading arm configurations are often used for chemical and industrial products; however, all products require specialized knowledge and equipment for a safe, efficient transfer. Each WSI chemical tanker or truck top loading arm is specifically engineered to match the exact nature of the product being handled. These are not petroleum loading arms with different elastomers.
