PTFE lined EPDM rubber expansion joints have advantages of PTFE and Rubber, PTFE can work in strong acid or strong alkali conditions, and rubber (EPDM) has very good flexible performance.
Flanges standard: AISI, DIN, JIS, BS etc, or customs design.
Flanges material: Carbon steel, SS304, SS316, or other material.
Body: EPDM, or Neoprene, Nature rubber, etc
Lining: PTFE (Teflon)
Size: DN50 (2") TO DN1000 (40")
Single Sphere Rubber expansion joints PTFE lined are widely used in paper mills, chemical plants and other piping applications where acids and highly corrosive chemicals are being handled. Our manufacturing capabilities include a complete range of Metal and Rubber Expansion Joints, lined in PTFE for transferring chemicals, strong acids, corrosives or other hazardous materials.
