Overview: The document provides technical specifications and applications for Teguflex® HP expansion joints, manufactured by Trelleborg. These joints are designed for use in various industrial applications, particularly where high temperatures and pressures are involved.
Specifications:- Material: Inner and outer tubes made of special EPDM, suitable for temperatures up to 130°C.
- Pressure Ratings: Maximum working pressure varies by diameter (DN 25-DN 600), with a range from 6 to 16 bar at 100°C and 6 to 10 bar at 130°C. Test pressure is 25 bar for smaller diameters and 15 bar for larger ones. Burst pressure exceeds 60 bar for smaller diameters and 30 bar for larger ones.
- Design: Includes unique fabric reinforcement resistant to hydrolysis, ensuring durability in high-temperature and moisture conditions. Available in building lengths of 130/200 mm with turnable flanges.
Applications:- Suitable for heating systems, industrial plants with hot water, vapour, and hot air.
- Compensates for thermal elongation and misalignment, isolates vibrations, and dampens noise and pressure surges.
- Resistant to acids, alkalis, alcohols, esters, and ketones, but not suitable for use with oil-based anti-corrosive agents.
Types and Movements:- Type U: Standard unit for axial, lateral, and angular movements.
- Type L: Includes tie bars for lateral movements.
- Type A: Features hinges for angular movements in one plane.
- Type L1 and L2: Include rubber bushes and spherical washers for smoother movements and vibration reduction.
Optional Equipment: Vacuum rings and flame guards are available.
Approvals and Standards: Complies with 97/23/CE, ISO 9001, ISO 14001, Germanischer Lloyds, and ABS standards.
Flange Details: Standard flanges are yellow chromated steel, with options for stainless steel and hot-dipped galvanized. Flange measurements conform to DIN 2501 PN 6/10/16 standards.
Dimensions and Movements: Detailed permissible movements, maximum vacuum support, and weight specifications are provided for each diameter size, ensuring proper selection for specific applications.
