Sleeve-type thermal expansion joint

Understanding sleeve-type thermal expansion joints

Thermal expansion joints with an inner sleeve are critical components in industrial piping systems, designed to compensate for changes in pipe length due to temperature fluctuations. When temperatures change, piping materials tend to expand or contract; without a compensation device, the system may become deformed or crack. This product helps maintain stability, ensuring the safety of the entire fluid transport system.

Technical specifications and construction of thermal expansion joints

The product is manufactured with key components including the bellows, internal sleeve, and external sleeve made of stainless steel, which enhances load-bearing capacity and protects the internal expansion element. This construction allows the joint to operate effectively in harsh environments.

Regarding construction materials, the end connections are produced from carbon steel or stainless steel (SS400, SUS304), meeting common connection standards such as JIS, ANSI, and DIN. Selecting the appropriate material and connection standard ensures the joint is easily compatible with existing piping systems in the factory.

Practical applications of thermal expansion joints in industry

Sleeve-type thermal expansion joints are widely used to transport various types of fluids such as hot steam, cold water, air, gas, and oil. With the ability to withstand temperatures up to 350ºC – 500ºC and a diverse working pressure range (up to 10, 20, 30... kgf/cm2), this device is a reliable choice for thermal power plants, boiler systems, chemical plants, and oil pipeline systems.

The expansion range of the joint reaches from -45mm to +10mm, ensuring the necessary compensation range for pipes ranging from 20A to 200A. The test pressure of the product is calculated according to the formula PT=PLV x (1.1 ÷ 1.5) kgf/cm2, ensuring safety before commissioning.
