Sleeve Type Expansion Joint
Sleeve type expansion joints are a simple and effective solution for accommodating axial thermal expansion in pipelines, ducts, and pressure vessels. This type of expansion joint consists of an inner sleeve (or slip pipe) that slides within an outer shell or sleeve,allowing for controlled axial movement between connected components.
The sealing between the sliding surfaces is typically maintained through the use of packing materials, O-rings, or gland arrangements, depending on the pressure, temperature, and media involved. Sleeve expansion joints are best suited for low to moderate pressure applications and are often used in systems where external protection from contaminants and ease of maintenance are priorities.
Design Standards
While not as complex as bellows-type joints, sleeve expansion joints can still be designed in accordance with relevant pressure design codes such as ASME Section VIII, depending on their application in pressure-containing systems. Material selection and seal design are critical for ensuring long-term performance.
The LSI-MECH sleeve type expansion joint is a robust and efficient solution for absorbing axial movement in pipelines, ducts, and low to moderate pressure systems. This design features a slip pipe or inner sleeve that moves within an outer shell, allowing for smooth axial displacement caused by thermal expansion or system movement.
Key Features of Sleeve Type Expansion Joints
- Allows for axial movement with minimal resistance
- Simple, rugged construction with fewer moving parts
- Suitable for moderate temperature and pressure applications
- Commonly used in ducting systems, air handling, steam lines,
- and industrial exhaust systems
- Can be designed with external packing or internal sealing for leak-tight performance
