Elaborate PTFE Joints

What is PTFE teflon?

Polytetrafluoroethylene (Polytetrafluoroethylene), abbreviated as PTFE, (commonly known as "Plastic King, Hala"), the trademark name Teflon, in China, due to the pronunciation of the reason, "Teflon In China, due to the pronunciation, the trademark "Teflon" is also called "Teflon", "Teflon", "Teflon", "Teflon Teflon", "Teflon", "Teflon", "Teflon", "Teflon" and so on, which are all phonetic translations of "Teflon".

What is PTFE Teflon fittings

1.Type:fittings, elbow, tee.1/8"-1",Fittings type: straight, 90° elbow, tee three kinds of fittings, fittings material (PTFE, PVDF, PFA, FEP) four kinds of fittings, according to the different process and technical requirements to choose different types of fittings. Dankai ferrule fittings are characterized by reliable connection, high pressure resistance, temperature resistance, good sealing and repeatability, easy installation and maintenance, safe and reliable work and so on.

2.Characteristics: high temperature resistance of 260 degrees, corrosion resistance, acid and alkali resistance, anti-aging, easy to install, easy to lock, not easy to deform after construction.

3.Installation form: buckling type, welding type, ferrule type, flaring type.

4.Characteristics: the joints have the characteristics of firm connection, high pressure resistance, good sealing performance, safe and reliable work.

How to connect Teflon pipe:

There are many ways to connect Teflon bellows, available flange connection, oil order connection, threaded connection, quick coupling, and direct connection with the guest, fixed with pipe clamps and wires. Details can be solved according to the specific application environment (application scenario).

Installation method of ptfe teflon ferrule fitting

ptfe fittings, also called polytetrafluoroethylene fittings, teflon fittings

Generally there are straight through, elbow, tee, cross, and valves (ball valves)

Fitting generally includes: joints, caps, ferrules three parts

Fitting specifications, generally based on the outside diameter of the tube connected to determine.

Tube through the nut, and then in this order through the ferrule, and then tighten.

Teflon Tubing and Fittings Characteristics

Commonly used characteristics:

Operating temperature: -200 degrees to 260 degrees Celsius

Ease of processing: can turn the edge

Aging resistance: can be exposed to ozone and sunlight for a long time without aging.

High transparency: low refractive index among all plastics, so you can visualize the flow of the medium inside the tube.

Corrosion resistance: able to withstand, in addition to molten alkali metals, fluorinated media and higher than 300 ° in addition to all strong acids, strong oxidizing agents, strong reducing agents and various organic solvents.

Strong reducing agents and a variety of organic solvents.

Unusual properties:

Density: 2.16-2.20g/cm3

Volume resistance＞1×1018

Surface resistance＞2×1013

Arc resistance＞165 seconds without leakage

Low water absorption: water absorption rate＜0.1%

Low coefficient of friction: small coefficient of friction

Surface non-adhesion: known solid material head can not be adhered to the surface

Non-combustibility: will not burn in the air, in line with the strict requirements of the fire place

Non-toxic: non-toxic, odorless, physiologically inert, no harm to people and the environment

Application

Applicable media: oil, water, gas and other non-corrosive or corrosive media. Which stainless steel fittings applicable media: seawater, steam, cold water, hot water, oxygen, drinking water, refrigeration, oil, gas, medical gas.
