PTFE lined Expansion Joints for Scandinavian customer

PTFE lined Expansion Joints for Scandinavian customer

Manufacturing PTFE-lined expansion joints shows the diverse application of this technology. PTFE (polytetrafluoroethylene) is known for its excellent chemical resistance and low friction properties, making it a popular choice for lining components in various industries.

Design codes and specifications of the Expansion Joints supplied:

  • Design codes EJMA latest edition / ASME
  • Type MFG PTFE lined
  • Size 600 mm and DN 400 mm
  • Bellows AISI 321 (1.4541/1.4878)
  • Lining PTFE
  • Flanges AISI 304L (1.4307)
  • Design temperature +100 °C 
  • Design Pressure 6,00 BARg
  • Test Pressure 8,60 BARg

Expansion joints are critical components used to absorb movements and vibration in piping systems, accommodating thermal expansion and contraction. By incorporating PTFE lining, these expansion joints can provide enhanced corrosion resistance and durability, making them suitable for demanding environments.
