Packaging & Delivery

Packaging Details We pack rubber expansion joints with neylon bags, wooden box,and according to your requirement.
  Rubber Expansion Joint with PTFE Liner
Product Description

Rubber Expansion Joint with PTFE Liner is made of Full face type rubber expansion joints or single/double arcg rubber expansion joints. PTFE Liner will make rubber expansion joints more anti-corrosion. All rubber impregnated construction will extend service life, molded integral rubber flange prevents pushing out under pressure, but only DIN and part of ANSI drilling available, other drilling standard only supply on request.

Rubber Expansion Joint with PTFE Liner Features and Benefit:

 

Corrosion resistant

Absorbs directional movement

Absorbs vibration, noise and shock

Compensates for more misalignment

Wide flowing arch design

Integral rubber flange design, prevent rubber end pulling out

No gaskets required; integrally rubber flanged design

Notes:
1. Supply range can be more than DN3000, detailed data can be offered upon request.
2. Control units must be used when piping is not properly anchored.
3. The rated pressure 2.5 MPa products will only be sold with control units.
4. Pressure rating is based on 30℃ operating temperature. The pressure rating is reduced at higher temperatures.
5. Weights in the above table are joints with DIN PN16 drilling retaining ring flanges.
6. Movements shown in the above table are non-concurrent.
7. Rated pressure in the above table is the maximum "working pressure". Test pressure is 1.5 times "working pressure", Burst pressure is 3 times " work pressure".
8. Normally, the flange drilling is based on DIN PN16, ANSI 150/250/300 lbs, BS PN10, JIS 10K are also available upon request.
