SG Expansion joints ondulated

SG Expansion joints ondulated

Axial Expansion Joints for the absorption of expansion in all hot or cold medium carrying piping systems, to facilitate assembly, to compensate foundation settlement and ground movement, to absorb vibrations of pumps, drive units, turbines, etc.
Expansion joints are used to compensate for thermal expansion compensation  and absorb vibrations in internal combustion engine exhaust systems. Easy to assemble, they are used in demanding conditions involving high temperatures, tensile, and compressive movements.
SG joints are essential components in many power transmission systems, absorbing vibrations, compensating for misalignments, and ensuring smooth and long-lasting operation. They are designed to meet diverse needs and ensure optimal performance under various operating conditions.

Key Advantages:

  • Vibration Absorption:
  • Misalignment Compensation
  • Noise Reduction
  • Ease of Installation and Maintenance


Applications

  • Automotive
  • Refrigeration
  • Earth moving machines
  • Gen sets, pumps, fans, engines, compressors and many others
  • on exhaust system in general


Technical features

  • Max. working temperature: 1112°F.
  • Metallic bellow stainless steel: AISI 321 (thickness 0,3 mm). 
  • Couplers: AISI304. From DN 125: FeP04
  • Welding: on resistance; from DN 125 TIG welding. 
  • Nominal pressure: PN 2,5 (0,245 MPa).
