PTFE corrugated pipe price
Polytetrafluoroethylene bellows refers to a tubular elastic sensitive element connected by a foldable wrinkle sheet along the direction of folding and stretching. Bellows are widely used in instrumentation, the main purpose is as a pressure measuring instrument measuring element, the pressure into displacement or force. The corrugated pipe wall is thin, the sensitivity is high, and the measuring range is tens of Pa to tens of MPa.
Its open end is fixed, the sealing end is in a free state, and the auxiliary coil spring or reed is used to increase the elasticity. When working, it elongates along the length of the pipe under the action of internal pressure, so that the movable end produces a certain relationship with the pressure. The movable end drives the pointer to directly indicate the size of the pressure.
The bellows is often combined with a displacement sensor to form a pressure sensor with an electrical output, and sometimes also used as an isolation element. Since the expansion of the bellows requires a large volume change, its response speed is lower than that of the Baudon tube. The bellows is suitable for measuring low pressures.
Teflon tube, scientific name Teflon tube (hereinafter referred to as F4 tube, Teflon tube) is a high-quality plunger extrusion tube, using special processing technology, so that the steel tube and plastic tube are closely combined, can bear positive pressure of 1.6Mpa, negative pressure: 77Kpa; It can be used normally at -60 ℃ ~ 260 ℃ and has reliable and excellent corrosion resistance. Transporting strong corrosive gases and liquids at high temperatures, which cannot be replaced by other pipelines.
PTFE tubes are extruded tubes, corrugated tubes, heat shrinkable tubes, plates, rods, films and other products, different products have different applications.
polytetrafluoroethylene corrugated pipe characteristics:
1. The use of a wide range of temperature (from -200 degrees Celsius to 260 degrees)
2. It is basically resistant to all chemicals except some fluorides and alkaline liquid metals.
3. Excellent mechanical properties including aging resistance especially for bending and swinging applications.
4. Outstanding flame retardancy (conforms to ASTM-D635 and D470 test procedures, and is regulated as a flame retardant material in air.
5. Excellent insulation characteristics (regardless of its frequency and temperature)
6. The water absorption rate is extremely low, and has a series of unique properties such as self-lubricating and non-stick
