Liquid Storage and Transport: Argon can be stored and transported in liquid form at temperatures below -185.7°C.
Gaseous Storage and Transport: The most common method for storing and transporting gases is to fill high-pressure steel cylinders with the gas for shipment. An argon cylinder is a cylindrical, high-pressure steel vessel; its exterior surface is painted gray and marked with the word "Argon" in green lettering. During use, argon cylinders must strictly not be struck or subjected to impact; if the cylinder valve freezes, it must not be thawed using an open flame. Argon cylinders must not be handled using electromagnetic lifting equipment. During the summer, they must be protected from direct sunlight exposure. The gas inside the cylinder must not be completely depleted; when returning a cylinder to the supplier, the residual pressure within the cylinder must be no less than 0.2 MPa. Argon cylinders are typically stored in an upright position.
