1.What isPTFETeflon
PTFE (Polytetrafluoroethylene), abbreviatedPTFE, (commonly known“Plastic King, Hala”), trade nameTeflon®, in
Because of the pronunciation,“Teflon”This trademark is also called“Teflon”,“Teflon”,“Tiefulong”,“Teflon”,“Teflon”Wait
and so on, all“Teflon”The transliteration.
2.PTFEBrief Introduction of Teflon Joint
1Type: the joint includes straight-through, elbow and tee.1/8"-1",The connector types are: straight through,90°There are three types of elbow and tee, and the joint materials are
（PTFE,PVDF,PFA,FEP) Four types, choose different types of joints according to different processes and technical requirements. Dankai ferrule fittinghave a connection
Reliable, high pressure resistance, temperature resistance, good sealing and repeatability, convenient installation and maintenance, safe and reliable work, etc.
2Characteristics: high temperature resistance260Degree, corrosion resistance, acid and alkali resistance, anti-aging, easy to install, easy to lock, not easy to deformation after construction.
3Installation form: buckling type, welding type, clamping type, flared type.
4Applicable medium: oil, water, gas and other non-corrosive or corrosive media. Which stainless steel joint applicable medium: sea water, steam, cold water, heat
Water, oxygen, drinking water, refrigeration, oil, gas, medical gas.
5Features: The joint has the characteristics of firm connection, high pressure resistance, good sealing performance, safe and reliable work, etc.

1. Teflon tubeHow to connect:
Teflon waveThere are many ways to connect the grain pipe, flange connection, oil connection can be usedThreaded connections, quick couplings and direct connections to customers
The connection is fixed with pipe clip and wire. Details may be resolved according to a specific application environment (application scenario).
2. What is the material of Teflon water pipe joint:
First of all, we need to understand that Teflon is dividedPTFE, FEP, PFA, ETFE several basic types:
TeflonPTFE:PTFE (polytetrafluoroethylene) non-stick coating can be used continuously at 260 ℃, with a maximum use temperature of 290-300 ℃, extremely low
Coefficient of friction, good wear resistance and excellent chemical stability.
TeflonFEP：FEP（fluorinated ethylene propylene copolymer) The non-stick coating melts and flows during baking to form a non-porous film, which has excellent chemical stability
excellent non-stick characteristics, the maximum use temperature is200 ° C.
TeflonPFA:PFA (perfluoroalkylate) Non-stick Coatings.Like FEP, the melt flows during baking to form a non-porous film. The advantage of PFA is that it has
Higher continuous use temperature 260 ℃, stronger toughnessEspecially suitable for use in the field of anti-stick and chemical resistance under high temperature conditions.

（15.88*19.05）1（22.2*25.4）
Can produce specifications, inner diameter0.5mm to 200mm inner diameter, wall thickness 0.12mm to 3mm.
5.PTFEFabrication Method of Teflon Joint
The utility model provides a Teflon joint, which comprises: a threaded part, a waist and a pin. The threaded part is a cylinder with an external thread.
The waist is a regular hexahedron, the pin is cylindrical;Threaded part, The other side is a pin, which is penetrated by a vacuum hole through the thread
Department, waist and pin. Thevacuum holeThe part of the hole diameter located in the thread part is enlarged, and the hole diameter is gradually enlarged at the opening of the thread part.
A bell mouth. The utility model has the advantages of compact structure, stable work, capable of preventing ignition and improving production efficiency.
