Product Details

The sleeve expansion joint is composed of a sleeve (core tube), shell, sealing material, etc. It can compensate the thermal expansion by sliding the sleeve to the external sleeve. It can be used to compensate the axial expansion of hot water, steam and grease pipes and the axial rotation of any Angle. It provides advantages like high-temperature resistance, corrosion resistance and anti-aging, applicable form -40℃ to 150℃, even up to 350℃. Some sleeve compensators are designed with an anti-break device, which can ensure that they will not be pulled apart when stretching to the limit position, thus greatly improving the safety of the whole pipe network operation.

The steel sleeve joint is mainly used to compensate axial displacement, lateral displacement or angular displacement (not recommended), is characterized by no thrust, corrosion resistance, high-temperature resistance, noise, and vibration attenuation, especially suitable for hot air pipe and smoke pipe. World iron&steel supply and manufacture sleeve joint coupling in accordance with EN, ASTM, GB standards and we also made a variety of materials for wider application. The materials used in the pipe system are directly related to how to join the pipes and what types of pressure assembled in the pipe. For more information, call us today!
