  Global Leaders in Cryogenic Tank Manufacturing DSW Engineering is a leading supplier of cryogenic tanks and ISO tank containers. We offer industry-leading manufacturing capabilities and deliver cryogenic storage tanks with exceptional stability and reliability. What is a Cryogenic Tank? Cryogenic tanks are specialized storage vessels designed to keep liquefied gases—such as oxygen, nitrogen, helium, argon, and hydrogen—at temperatures below -150°C. These tanks use a combination of low temperatures and pressure to store gases in a liquid state, enhancing storage density and reducing liquefaction energy requirements. What Are Tank Containers? Tank containers are essential for transporting liquids, gases, and hazardous materials. They come in various sizes and types to ensure safe and efficient shipping, including ISO containers. Choosing the correct tank container is crucial for maintaining the integrity of bulk products, chemicals, and food-grade materials during transport. DSW Engi

  Definitions and Classifications of Gases Classifications of Gases Compressed Gases Characteristics: Non-liquefied at ordinary temperatures, even under high pressure. Stored at high pressures in containers. Pressure Criteria: A gas or mixture of gases in a container with an absolute pressure exceeding 40 psi at 70°F (21°C). A gas or mixture of gases in a container with an absolute pressure exceeding 104 psi at 130°F (54°C), regardless of the pressure at 70°F (21°C). A liquid with a vapour pressure exceeding 40 psi at 100°F (38°C), as determined by ASTM D-323-72. Examples: Helium Nitrogen Oxygen Argon Liquefied Compressed Gases Characteristics: Become liquid at normal temperatures when pressurized inside a cylinder. Examples: Ammonia Chlorine Methane Natural Gas Liquefied Petroleum Gas (LPG) (e.g., Propane and Butane) Refrigerated Liquefied Gases (Cryogens) Characteristics: Maintained at very low temperatures. Boiling points below -150°C. Heavier than air at cold temperatures, accumula

  Detailed Production Process of Cryogenic Pressure Vessels Cryogenic pressure vessels are specialized equipment extensively used in the chemical, petroleum, and energy industries, primarily for storing and transporting liquefied gases. Their production process is meticulous and complex, involving several critical steps. Below is the primary production process for cryogenic pressure vessels: store and transport liquefied gases Design and Material Selection: The design of cryogenic pressure vessels must comply with relevant safety standards and regulations, such as ASME and GB. The design considerations include the vessel's working pressure, temperature, volume, and the characteristics of the contained medium. Material selection is crucial, typically involving steels with excellent cryogenic properties, such as 9% nickel steel, to ensure good mechanical performance at extremely low temperatures. Cutting and Forming: Once the materials pass inspection, they are cut according to t

  The Vital Role of Cryogenic Storage Tanks Cryogenic storage tanks are specialized containers that keep liquid gases below -150°C. These tanks enable the efficient storage and transportation of cryogenic liquids, which would otherwise evaporate into gaseous forms under ambient conditions. Today, cryogenic tanks are essential to many cutting-edge industries. Understanding Cryogenic Storage Tanks Importance Understanding the design, construction, and operation of cryogenic tanks is crucial. This knowledge equips scientists, engineers, and operations staff with the expertise to maximize cryogenics' potential while ensuring sustainability, safety, and efficiency. A solid grasp of cryogenic concepts and applications fosters innovation. Basics Definition Cryogenic storage tanks feature double-walled constructions with thermally insulated interiors. The inner vessel, made of stainless steel or aluminium alloy, contains the liquid cryogen. The outer shell provides additional insulation a
