A cryogenic piping system is a piping system used to transport and store cryogenic fluids. Here’s a detailed explanation of the cryogenic piping system:
Definition
Cryogenic piping systems usually refer to piping systems used to transport media at temperatures below -45°C. These systems are widely used in industries that require a low-temperature environment, such as chemical, medical, refining, and natural gas and petrochemical.
Peculiarity
Material: Low-temperature pipes are generally made of steel pipes, stainless steel pipes and other materials, which have good low temperature resistance and can maintain structural stability at extremely low temperatures.
Operating pressure: Cryogenic pipes are usually pressure pipes with high operating pressures because cryogenic media usually need to be at higher pressures to remain in a liquid state.
Safety risks: Due to the harsh working environment, cryogenic piping systems have certain safety risks and regulatory requirements. During the design and manufacturing process, a range of technical technical measures are required to ensure the tightness and reliability of the pipeline.
Apply
Chemical industry: used to transport chemicals and intermediates, such as basic chemicals and specialty chemicals. By keeping the liquid in the pipeline at a low temperature, the evaporation of chemicals and environmental contamination can be avoided.
Medical industry: used for the delivery of liquid oxygen, liquid nitrogen and other gases, for the cryopreservation of biological samples and the preparation of medical preparations.
Refining industry: It helps to transport crude oil and refined products to different locations, reducing vaporization losses and environmental pollution of oil.
Natural gas and petrochemical industry: Conveying LNG through flow control, pressure regulation, and refrigeration and cooling measures to improve economic efficiency.
Design & Manufacture
When designing and manufacturing cryogenic piping systems, factors such as the nature of the medium, temperature, and pressure need to be considered. At the same time, it is also necessary to pay attention to the installation and maintenance of pipelines to ensure that they are operated in accordance with certain specifications and standards.
Security Issues
Cryogenic piping systems require special attention to safety during design, manufacture, installation, and maintenance. Due to the harsh working environment, leaks or other malfunctions can cause serious damage to personnel and equipment. Therefore, appropriate safety measures need to be taken, such as regular inspections, repairs and replacement of aging parts.
In short, a cryogenic piping system is a kind of piping system specially used for the transmission and storage of cryogenic fluids, which has unique characteristics and application fields, and has strict requirements for materials, design, manufacturing and safety.
