Carbon Steel Storage Tank for Liquefied Gas Storage: Used for pressurized vessels, requiring specific low-temperature alloys for cryogenic gas

Liquefied Gas Storage encompasses a wide variety of products, ranging from moderate-pressure gases like propane and butane to cryogenic gases such as Liquefied Natural Gas (LNG) and liquid oxygen. All these products are stored under pressure or at extremely low temperatures to achieve liquid density. The Carbon Steel Storage Tank is used for pressurized vessels across this spectrum, providing the necessary strength for medium-pressure gases. However, when storing cryogenic gas—which involves temperatures far below zero—the material requirement shifts, requiring specific low-temperature alloys to prevent catastrophic brittle failure.

Product Advantages and Features: Strength for Pressure, Material Specialization, and Safety

A Carbon Steel Storage Tank is the proven, practical structure for Liquefied Gas Storage in non-cryogenic applications, offering a critical combination of physical strength, regulatory compliance, and inherent safety.

Used for Pressurized Vessels: For gases liquefied under moderate pressure (e.g., LPG/propane), carbon steel is readily used for pressurized vessels (spheres or horizontal cylinders). Its high tensile strength is essential for safely containing the internal pressure, which is critical for maintaining the product in its liquid state. These pressure vessels are built to stringent codes like the ASME Boiler and Pressure Vessel Code.

Cryogenic Requirement: When dealing with extremely cold cryogenic gas , standard carbon steel cannot be used because it becomes brittle and prone to failure at such low temperatures. The storage vessel then shifts, requiring specific low-temperature alloys such as high-nickel steel (like 9% nickel steel) or stainless steel for the inner containment vessel.

Dual-Containment Structure: Large cryogenic Liquefied Gas Storage tanks often employ a dual-containment design. The outer tank, which provides structural support and external weather protection, is frequently built from standard Carbon Steel, while the inner tank, which contacts the cryogenic gas, is built from the low-temperature alloy. This dual approach maximizes safety and cost-efficiency.

Structural Integrity and Compliance: Regardless of the temperature extreme, the entire tank system demands exceptional structural integrity. The carbon steel portions of the vessels are fabricated using specialized welding and heat treatment procedures to ensure the highest level of joint efficiency and overall shell durability, which is paramount for safety.

Cost-Effective Bulk Containment: For large-scale LPG and moderate-pressure gas storage, the efficient fabrication and cost of carbon steel make it the most economical choice for achieving the necessary high strength and vast bulk containment volumes.

Product Applications

The Carbon Steel Storage Tank for Liquefied Gas Storage is an indispensable asset utilized across the entire energy, chemical, and industrial gas supply chains.

LPG (Propane/Butane) Terminals: The core application, using robust Carbon Steel pressurized vessels (spheres or horizontal bullets) to store liquefied petroleum gas for residential, commercial, and industrial distribution.

Industrial Gas Facilities: Used for storing various pressurized gases (e.g., anhydrous ammonia or chlorine), where the strength is critical for safety and containment integrity.

LNG Import/Export Terminals: The outer shell and supporting structures of massive LNG storage tanks are typically built from standard carbon steel, while the inner tank contains the cryogenic gas and is fabricated from the specialized low-temperature alloys.

Petrochemical Feedstock Storage: Employed for storing bulk quantities of liquefied hydrocarbon gases (e.g., ethylene, propylene) before they enter the processing stream.

Utility Peak Shaving Operations: Used by utilities to store LPG or similar gases in liquid form, providing the dense storage capacity required to supplement natural gas supplies during peak demand.
