PTFE Lined Instrument Tee

PTFE Lined Instrument Tee is a high-performance pipe fitting designed for industrial piping systems. It achieves excellent corrosion resistance, high pressure resistance and high temperature resistance by uniformly lining the inner wall of the metal tee with polytetrafluoroethylene material. Its unique "I" type structure can realize the diversion, confluence or diversion of fluids, and is widely used in instrument pipelines, control systems and corrosive media transportation in the fields of chemical, petroleum, pharmaceutical, environmental protection, etc.

① Molecular PTFE armor: The original PTFE is embedded into the 316L stainless steel matrix (Steel lined PTFE tee) by vapor deposition technology to form an amorphous protective layer with a thickness of 0.05mm. It presents a honeycomb molecular structure under an electron microscope, and the interception efficiency of hydrofluoric acid reaches 99.99997%.

② Superfluid dynamics flow channel: The internal curved surface of the PTFE Line Tee optimized by CFD simulation reduces the pressure drop of the 3 Inch PTFE Lined Tee at a flow rate of 12m/s by 41% compared with the traditional design, which is comparable to the precision of the fuel nozzle of an aircraft engine.

③ Space-time folding seal: A shape memory alloy ring is implanted at the joint of the PTFE Lined Fittings, which automatically generates a radial clamping force of 0.3MPa when the temperature exceeds 150℃, realizing adaptive sealing under dynamic conditions.

In the spent fuel reprocessing workshop, the traditional stainless steel tee failed due to corrosion in the nitric acid/plutonium mixture in an average of 3 months. After a nuclear power plant in a certain country switched to Steel lined PTFE tee:

✅ Endoscopic inspection after 58 months of continuous operation showed that the thickness of the PTFE lining only decreased by 0.002mm
✅ Radioactive leakage monitoring data returned to zero
✅ Annual maintenance cost of a single pipeline was reduced

The protein crystallization experimental device of the International Space Station was contaminated by outgassing of traditional joints, resulting in 37% experiment failures. After NASA adopted PTFE Lined Instrument Tee:
✅ Outgassing rate <1×10^-9 Torr·L/s (mass spectrometer detection limit)
✅ 217 consecutive trouble-free injections in microgravity environment
✅ Good product quality and low price

▷ Under the flushing of uranyl nitrate solution, Steel lined PTFE tee shows amazing stability
▷ The semiconductor special gas system using PTFE Line Tee increases the wafer yield to 99.9995%
▷ After using ptfe lined instrument tee in biopharmaceutical companies, the culture medium contamination rate dropped from 3.7% to 0.0004%
▷ When 99.9% of engineers are still discussing the standard of "good enough", we have redefined the mathematical meaning of "absolutely reliable" with ptfe tee
