PTFE Expansion Joint, PTFE Metal Expansion Joint, PTFE Rubber Expansion Joint

PTFE Expansion Joint has a structure with a reinforce ring as a bellows retainer on PTFE, can use Carbon Steel or Stainless Steel for the flange. PTFE it is suitable for use with all chemical products and compensates for repeated thermal expansion in pipes. It can withstand various concentrations of acids, alkalis, and salts, and has the advantage of pressure on PTFE stainless steel expansion joints.

The Advantage:

  • Available in sizes 1” to 48” ID.
  • Available for 3 and 5 convolutions bellows.
  • Reinforced bellows use for high-pressure service.
  • Full vacuum up to 180°C.
  • PTFE lined stainless steel compensator available for very high pressure service.
  • PTFE Food-grade quality.

The Expansion Joint outer body is a stainless steel metal that combines the properties of metal and PTFE into the most advance on the market. There is additional Types of Expansion Joints like Lined, Hinged, Dual and Universal Tied.

The Advantage:

  • High degree of reliability.
  • Long service life.
  • Available in size DN25-DN3000mm can be provided.
  • Working temperature from -300◦F to +400◦F.
  • Working Pressure: 50, 150 and 300 PSIG.

PTFE metal expansion joints can be manufactured in special lengths and in special movement capabilities (according to requirements). Consult for information on the specific construction you need for your application.

Rubber expansion joints with PTFE are designed similarly to other types, namely to reduce piping pressure, absorb pipe misalignment, compression and extension, noise and vibration, in a relatively short space of time. But this item has better flexibility at a lower price.

Material : EPDM, NBR, Viton
Liner : PTFE (Food-grade)

The advantage:

  • Wide temperature range  (-20 C to 100 C)
  • Absorb vibration, noise, and shock
  • Greater movement capability
  • Maximum resistance to chemicals and solvents
  • Electrically insulating
  • Wide variety  of elastomer
