Fully PTFE lined flanged corrugated bellow expansion joint compensator with booster ring
Fully PTFE lined corrugated bellow expansion joint
Expansion Bellows are an indispensable part of a piping system. These can withstand design temperature, pressures both negative as well as positive, misalignment, vibrations and provide the necessary capacity to absorb thermal growth of the piping system. The movement can be axial, lateral or angular where our expansion bellows stand apart. The pressure thrust of expansion joint too is restrained by use of tie bolts and reinforcing rings. Convolution design is perfect for strength and flexibility.
We offer a variety of expansion joints such as single and double expansion joints, universal expansion joints, pressure balance expansion joints, gimbal expansion and hinged expansion joints, rectangular expansion joints, metal hoses.
PTFE lined corrugated bellow expansion joint for thermal expansion in pipelines, for the protection of fragile process equipment such as graphite, plastic or glass and the isolation of vibration hazards. PTFE bellows come into their own for corrosive, high purity or hot applications. we have some unique manufacturing processes based upon the use of paste extruded PTFE, and a proprietary convolution process to secure a uniform wall thickness and highest pressure-temperature ratings in the market.

Characteristic of PTFE metal expansion joint
1. Polytetrafluoroethylene theoretical temperature is -200 to 260 degrees Celsius, the actual recommended temperature is -170 to 230 degrees Celsius.
2. Polytetrafluoroethylene has a very small surface length and wetting angle, so it has a non sticky surface.
3. It is also chemically inert and can tolerate all media except for molten alkali metals and their oxides.
4. The surface of polytetrafluoroethylene is the smallest coefficient of friction found in solid articles so far.
5. At present, the domestic Teflon lined rubber joints are not closely attached to the structure. Pressure and pressure over 6 kilograms
Packing and delivery
Each PTFE expansion joint is wrapped in plastic film or bags,
Then it is put into the carton case ,
At last all the small carton cases are put into the wooden case.
The wooden case is normally 1.1*1.1*1.1.
Or can as per client's requests.
