Are compression fittings suitable for high or low temperature environments?

Compression fittings are widely used in various industrial pipeline connections, and their application range covers a variety of working environments, including high and low temperature environments. Due to the flexible structural design and material selection of compression fittings, they can adapt to working requirements under different temperature conditions and provide reliable pipeline connections.
In high temperature environments, the applicability of compression fittings mainly depends on the heat resistance of the sealing material and the fitting itself. Usually, the sealing ring of compression fittings is made of high temperature resistant materials, such as fluororubber, polytetrafluoroethylene (PTFE) or high temperature silicone, which can withstand a certain range of high temperatures without losing elasticity or causing sealing failure. For some specific high temperature industrial applications, such as the chemical, oil and gas industries, pipeline systems working at high temperatures require the fittings to maintain their sealing performance and connection stability for a long time. At this time, choosing the right sealing ring material and optimizing the joint structure is the key to ensuring the normal operation of compression fittings in high temperature environments.
Compression fittings also have a certain resistance to thermal expansion, which enables them to adapt to the expansion and contraction caused by temperature changes. Especially in high temperature environments that require frequent changes, compression fittings can effectively cope with changes in pipeline stress caused by temperature fluctuations. Its compression can ensure sealing in high temperature environment and avoid leakage of high temperature fluid.
Compression fittings are also suitable for low temperature environment, especially in some low temperature fluid delivery systems, such as liquefied natural gas (LNG), liquid nitrogen, etc. Pipes and joints in low temperature environment face the problem that the temperature may be too low, which may cause the material to become brittle. For this reason, the materials of compression fittings are usually made of low temperature resistant metals and sealing rings. For example, the sealing ring material may be made of fluororubber or other materials with good low temperature performance to ensure that it will not harden or lose elasticity under low temperature conditions and maintain sealing performance. Compression fittings can withstand large temperature differences at low temperatures, ensuring stable sealing in extremely cold environments.
A major challenge in low temperature environments is the brittleness of materials and the effects of thermal expansion and contraction. The design of compression fittings takes these issues into consideration. The metal material of the joint is generally selected from low temperature resistant alloy steel or stainless steel. These materials have good brittleness resistance and low temperature toughness, which can avoid loose connection or leakage caused by thermal expansion and contraction in low temperature environments.
Although compression fittings are suitable for high and low temperature environments, their actual performance is limited to the specific operating temperature range. To ensure reliable operation at extreme temperatures, users should select appropriate sealing materials and joint models according to specific temperature requirements when selecting ferrule pipe fittings. When the temperature exceeds the recommended range of the joint and sealing material, the sealing may be affected, resulting in leakage or joint damage. Therefore, under high or low temperature conditions, the operating temperature of the ferrule pipe fitting should be fully evaluated before use, and ensure that the product that meets the standards is selected.
