PTFE Expansion Joints with 3 TIE RODS CARBON STEEL ANSI150 DN150


PTFE bellows expansion joints also known as expansion bellows.It is composed of a corrugated pipe (an elastic element), an end pipe, a bracket, a conduit and other accessories.PTFE bellows expansion joints is a compensation element, effective use of bellows telescopic body deformation, dimensional change in absorption pipeline,thermal expansion and contraction caused by the container, or compensation pipeline, conduit, vessel axial, transverse and angular displacement.


Performance characteristics

1. Excellent chemical resistance
2. High and low temperature resistance(-100°C to 260°C)
3. High pressure resistance
4. Anti-aging,long life without an aging problem
5. Wear resistance, high lubrication
6. Anti-corrosion ,non-stick, easily cleaned
7. Fire resistance
8. Electrically insulated
9. Excellent flexibility


In particular, the properties of PTFE are as follows: 


Corrosion resistance: it can withstand the action of all strong acids (including aqua regia), strong oxidant, reducing agent and various organic solvents except molten alkali metal, fluorinated medium and sodium hydroxide higher than 300 ℃.


Inside: PTFE hose, the hose can be smoothbore PTFE , and also convoluted , for high and low temperature used, anti-corrosive, non-stick.
Outside: SUS304 Stainless steel braided. High pressure resistance. All kinds of couplings can be available

Note: 1. Special requirements can be customized according to the user's drawings. The flange standard is GB / t9115.1-2000. A variety of flange standards (GB, JB, Hg, CB, ANSI, DIN, BSEN, NF, en, JIS, ISO, etc.) can be selected for production. Rubber spheres can be used as natural rubber, EPDM, chloroprene rubber, butyl rubber, butadiene green rubber, fluororubber, etc.2. When the suspended water supply uses products above DN200, the pipeline must have fixed support or fixed bracket, otherwise the product should be installed with anti pull off device.
