Cryogenic piping refers to piping systems with a design temperature lower than or equal to -20°C. These pipelines are typically used to transport cryogenic media such as liquid nitrogen, liquid oxygen, liquefied natural gas (LNG), etc., in a cryogenic environment. Cryogenic pipes are used in a wide range of industries, including oil and gas extraction, chemicals, food refrigeration, medical and scientific research.
Because cryogenic pipes convey extremely low temperatures, piping materials and designs must be able to withstand the challenges of this cryogenic environment. For example, pipe materials need to maintain sufficient strength and toughness at low temperatures to prevent embrittlement and cracking of the material due to temperature drops. In addition, the design of cryogenic pipes also needs to consider insulation and protection against thermal bridging effects to reduce heat loss and avoid icing in the environment around the pipes.
When designing and installing cryogenic piping, relevant standards and specifications must be followed to ensure the safety and reliability of the piping system. These standards and specifications typically include requirements for material selection, piping design, welding and joining, insulation and insulation, testing and inspection, and more.
In conclusion, cryogenic piping is a piping system used to transport cryogenic media in a cryogenic environment, and its design and installation require special considerations and measures to ensure the safety and reliability of the system.
