Teflon compensators are also different in different kinds of pressure grades

Release date:2017-12-05 Author:www.jsyyjx.com.cn Click:

Polytetrafluoroethylene bellows compensator (also called expansion joint) is used to compensate the displacement and installation deviation of thermal expansion and cold contraction in the pipeline system of strong corrosive medium, so as to reduce the vibration of pipeline system.

The basic parameters of the Teflon compensator: (1) nominal pressure MPa:-0.01, -0.05, 0.01, 0.05, 0.1, 0.25, 0.6, 1;

Second, the nominal path and the amount of compensation are shown in the following table.

The working temperature is -50 ~ 150 C, more than 150 degrees centigrade.

The tetrafluoroethylene compensator is divided into many kinds.

1. PTFE lining compensator: body stainless steel metal lining PTFE. Resistant to various concentrations of acid and alkali, salt, and together with the stainless steel pressure compensator, no collision etc.. Pressure rating: PN0.6, 1, 1.6MPa; temperature: less than or equal to 180 DEG C.

2. spray type Teflon compensator: the outer body is the stainless steel metal compensator, and the internal spraying Halar ECTFE, F40, PFA and other fluorine materials. In corrosion resistance than steel PTFE or PTFE medium voltage compensator compensator is slightly worse. Provide DN25-DN3000mm; wave number is not restricted, the length is less than or equal to 3000mm more than 10000 times the number of fatigue: pressure rating: PN0.25-2.5MPa temperature: less than or equal to 180 DEG C.

3. medium voltage network set of tetrafluoroethylene compensator. The outer body is a stainless steel weave, and it is PTFE. Resistant to various concentrations of acid, alkali, salt, organic solvent. The market is available for DN25~DN600mm, and the number of continuous fatigue is >5000 times. Pressure grade: PN0.6MPa, PN1.0MPa. Temperature: less than or equal to 200 DEG C.

4. pure tetrafluoroethylene compensator: generally used in the low pressure pipe. Pressure level; PN0.01-0.6MPa, the materials connected at both ends are generally carbon steel flanges, and all kinds of non-standard flanges are made according to customers, and other materials are plastic and stainless steel.
