Flexible Axial Compensation For Thermal Expansion And Vibration
Sleeve compensators provide reliable axial movement compensation and corrosion resistance for industrial piping, ensuring durability in high-pressure and high-temperature systems.
Sleeve Compensators, also known as sleeve-type expansion joints, are vital components in industrial piping solutions, designed to absorb axial movement caused by thermal expansion and contraction while ensuring system integrity. Constructed from materials like stainless steel, carbon steel, or copper, these compensators offer excellent corrosion resistance and durability, making them ideal for applications in power plants, chemical processing, water supply systems, and boiler pipeline protection. Their non-thrust design minimizes stress on adjacent equipment, enhancing system reliability.
Available in sizes from 2” to 36” (DN50 to DN900), sleeve compensators are suitable for pressures up to 2.5 MPa and temperatures ranging from -40°C to 600°C, depending on the material and sealing configuration. They feature a sliding sleeve mechanism with flexible graphite or EPDM seals, providing low friction (0.04-0.10) and robust sealing to prevent leaks. These compensators are designed for axial movement compensation, with single-way and two-way structures available to accommodate varying pipeline requirements. They comply with standards like API 1102 and ASME Section VIII for quality assurance.
The sleeve compensator excels in environments with high chloride ion content, as its sealing materials resist corrosion in saltwater and harsh chemical conditions. The sliding surface offers corrosion resistance up to 50 times higher than austenitic stainless steel in saline environments, ensuring a long service life equivalent to the pipeline itself. Maintenance is straightforward—worn seals can be replaced by re-fastening the flange or adding additional seal layers, extending usability without costly replacements.
Compared to bellows-type expansion joints, sleeve compensators are simpler and more cost-effective for axial movement, though they are less suited for lateral or angular displacements. They are ideal for hot water, steam, and oil pipelines, with applications in district heating, municipal water projects, and industrial networks. Installation is simplified with flanged, threaded, or welded ends, and proper anchoring ensures axial alignment. Regular maintenance, such as tightening bolts after 24 hours of operation, enhances sealing performance and system longevity.
Sleeve compensators address critical challenges like pipeline wear, thermal stress, and corrosion in high-throughput systems. Their robust design, combined with corrosion resistance and axial movement compensation, makes them a preferred choice for engineers seeking reliable, low-maintenance solutions for industrial piping and boiler pipeline protection, ensuring safety and efficiency in demanding environments.

The sleeve type compensator/tube type expansion joint adopts a new type of sealing material flexible graphite ring, which has the characteristics of high strength, no aging, good effect and convenient maintenance. The tubular telescopic joint has a long service life and a fatigue life comparable to that of a pipe.
The sleeve compensator, also known as a pipe-type expansion joint, functions as a compensating device within hot fluid pipelines. Its primary application is in the auxiliary equipment of straight pipelines. It is suitable for conveying hot water, steam, grease, and other media. It achieves thermal expansion compensation through the sliding movement of the inner sleeve relative to the outer sleeve.
The sleeve compensator is designed for use in medium engineering applications with a pressure rating of ≤2.5MPa and is suitable for a temperature range of -40℃ to 600℃.
This compensator employs a new type of sealing material, namely, a flexible graphite ring. This material offers several advantages, including high strength, a low friction coefficient (0.04~0.10), resistance to aging, and effective sealing, along with easy maintenance.
The sleeve compensator boasts a lengthy service life, with fatigue resistance equivalent to that of the pipeline. Its sliding surface is specially treated to provide excellent corrosion resistance, even in saltwater, salt solutions, and similar environments, surpassing austenitic stainless steel by over 50 times. In cases where the sealing effect weakens due to wear over many years, the flange can be retightened to enhance the sealing performance. Alternatively, the bolts can be loosened, the pressure ring can be removed, and one or two layers of sealing rings can be added to compress the pressure ring for continued use.
