Special Welding DN150 PN25 Sleeve Compensator For Thermal Pipeline

The sleeve compensator, also known as the tubular expansion joint, is a compensation device for hot fluid pipelines, primarily used to absorb axial thermal expansion displacement caused by temperature changes. It is widely implemented in transmission pipelines across various industries including urban heating, metallurgy, mining, power generation, petrochemical, and construction.

The sleeve compensator consists of three main components:

• Sleeve (Core Tube): Connected to the pipeline, utilizing high-performance self-pressure dynamic sealing
• Shell: Allows free sliding movement of the inner sleeve during pipeline expansion/contraction
• Sealing Material: Advanced synthetic material resistant to high temperatures (-40°C to 150°C, extendable to 350°C), corrosion, and aging

The compensator operates through sliding motion between sleeve and outer sleeve, accommodating:

• Axial pipeline expansion/contraction
• Axial rotation at any angle
• Ideal for hot water, steam, and grease media
• Compact design with significant compensation capacity
