The Procedure for Manufacturing a Storage Tank

Storage tanks are indispensable structures for storing liquids or gases across various industries, from manufacturing to transportation. The process of manufacturing these tanks can vary widely depending on the material used and the specific requirements of the industry. This article provides an in-depth look at the procedures involved in manufacturing storage tanks, combining advanced technologies and rigorous quality control measures.

Materials and Manufacturing Techniques

The two primary methods of manufacturing storage tanks include rolled welded steel injection molding and hand-laid fiberglass. Each method has its advantages and is suited to different applications:

Rolled Welded Steel: This involves the use of heavy and expensive equipment. It is highly durable and suitable for storing corrosive or highly pressurized substances. The process typically starts with a contract from the government, followed by the supply of funds and a final delivery payment. Hand-Laid Fiberglass: This method is lighter and more flexible, making it ideal for storing less corrosive liquids or for applications where weight is a concern. It involves a manual process of laying up fiberglass cloth in layers over a mold, which hardens into the desired shape.

Before the fabrication process begins, the hull of the tank is prepared. The axels and drive wheels are installed later in the assembly line. The framing and armor are built around the hull, followed by the installation of the engine and electronics. The turret and cannon are fixed next, along with the ammunition storage compartment. The breach is installed last to ensure a watertight seal. Once the components are in place, the tank undergoes flaw detection and painting before being sent to a modification division where upgrades are applied as requested by the army procurement team.

Historical Context and Evolution

Historically, tank manufacturing involved a series of intricate steps:

The metal was hardened to specific units (though the exact unit is forgotten now). The hull body and turret were welded together. Metals were cut and shaped into doors and other necessary openings for the engine and other devices. Exterior painting occurred after the turret was mated to the hull.

This process reflects the evolution of manufacturing techniques, from manual labor to advanced machinery and composite materials. The modern approach to tank manufacturing involves a combination of precision engineering and advanced materials to ensure durability and efficiency.

Modern Techniques and Classification

For modern storage tanks, the specific details of the manufacturing process are often classified and protected by tank-producing companies. Generally, the hulls and turrets are cast or welded, with welding trending towards the use of non-castable and non-weldable composite armor packages. This not only enhances the structural integrity of the tank but also allows for greater flexibility in the design of the armor.

Following the fabrication of major components, interior painting is done, and the internals are mounted to the hull and turret. Major items such as guns and motors are installed. The running gear and tracks are assembled to the hull, and the hull moves forward on an assembly line. The turret, which is more or less complete, is then mated to the hull after all the major components and sub-assemblies are installed. For the M1, exterior painting occurs after the turret is mated to the hull.

The process of manufacturing storage tanks is a complex one, involving a combination of advanced techniques and rigorous quality control measures. From the initial contract to the final painting and modifications, every step is meticulously planned and executed to ensure the tank is both functional and safe for use.
