A333 stage 1 tubes are primarily made of carbon steel with lower carbon content and some other alloying elements. This helps provide the required low-temperature toughness as well as sufficient strength and plasticity.
A333 Class 1 piping is suitable for extremely low temperature conditions. It is typically used in temperatures ranging from -50°F (-45°C) and below. Due to its low-temperature properties, the pipeline has important applications in liquefied natural gas (LNG) processing, frozen food industry and other fields.
A333 GR 1 cryogenic pipe has excellent low temperature resistance and can maintain good mechanical properties and corrosion resistance at extremely low temperatures. It is suitable for pipeline transportation and equipment manufacturing under low temperature conditions. Able to withstand impact and pressure in low-temperature environments, it is suitable for delivery systems of low-temperature gases and liquids.
Widely used: A333 GR 1 pipe is widely used in cryogenic pipeline systems in petroleum, natural gas, chemical and other industries, and is especially suitable for the transportation of cryogenic liquids such as liquefied natural gas (LNG) and liquefied petroleum gas (LPG).
