PTFE Tubes - Uses in Oil & Gas industries

Polytetrafluoroethylene (PTFE tubes), also known as Teflon, commercially is a fluoropolymer of unique properties which is widely used in a number of products and branches of industry.

Basic properties of PTFE which as perfect hose material are the following,

Offers excellent chemical resistance to almost all chemicals;

The working temperature is extremely wide it ranges from (from -70°C to +260°C as a standard);

It offers excellent resistance to varied weather conditions;

It has self-cleaning properties as it has a non-stick surface.

 Hoses are manufactured not from PTFE alone but also from other similar fluoropolymers, for example, FEP, MFA, PFA, ETFE, ECTFE. They feature a number f mechanical resistance and varied processing properties.

Nowadays, hoses that are made of PTFE and similar fluoropolymers are used in numerous sectors of the industry. For example for steam, fuel, hot oil, paint, adhesives, high-pressure gas transfer and so on. In the chemical industry, they are used for a number of activities such as loading and unloading of acids, bases, extremely aggressive chemicals, and organic solvents. PTFE tubings and hoses assemblies ensure highly efficient and hygienic transfer and perfectly suit a number of objects such as food, the cosmetic, pharmaceutical industry, also biotechnology.

These are other hoses made of PTFE and other fluoropolymers and they belong to the following hoses such as chemical hoses, ducting hoses, high-pressure gases, food hoses, composite hoses, and brake hoses.

Fittings that are perfect for PTFE hoses that are assembled in PTFE hoses. Sometimes there are hydraulic fittings or fittings for specific industrial hoses can be also assembled.

When a few of the substances are conveyed in PTFE hose, electrostatic charges may be built up in the hose wall. So, if you want to avoid the static electricity, an antistatic version of PTFE which has lower electrical resistance is highly recommended.

Essential Component Characteristics of PTFE Hoses

Excellent aging; you notice very little change in the mechanical properties over time

It is (ESCR) Environmental stress crack resistance.

Non-stick properties or Low surface energy.

Low permeation

Superb chemical resistance

Offers excellent flexibility or ductility at very low temperatures.

It is non-flammable

How to Install PTFE Hose Fittings - A Quick Guide

Polytetrafluoroethylene also knew as PTFE is an opaque white fluoropolymer that can be chemically created and the process is known as free radical polymerization or using the process of multiple tetrafluoroethene molecules. PTFE is used in a wide number of applications and industries such as automotive, aerospace also telecom.

You’ll discover that PTFE tubes or rods are combined with metals such as stainless steel or carbon that increases the strength and wear resistance.

PTFE Properties

PTFE has a few distinctive properties and that is why it is preferred by most industries. It is resistant to chemicals, heat, electricity, and it is highly flexible as well. 

PTFE has a melting point of 327 degree Celsius and it is chemically inert. Even when it is put through extreme temperatures such as high temperatures (260-degree Celsius) and low temperatures (-200 degree Celsius) it does not change or shows any signs of degradation. Check out some of the other important features here. 

·         It has great flexural strength in low temperatures.

·         It has the impressive electrical strength

·         Its dielectric strength is potent.

·         Its water resistance power is great

·         It has a low coefficient of friction

·         Its density level is very high.

The fact that PTFE hoses are chemically inert that it only reacts to only a few chemicals, so the only way to cause any impact on it is via energy radiation. 

The Tools Required for Fitting PTFE Hose

Check out what are the tools you require here,

·         Bench mounted vice

·         Light oil, 3 in 1 or similar

·         Imperial sized spanners (has to have a polished face)

·         Small screwdriver or pick

·         Fine tooth saw such as junior hacksaw

·         Hobby knife

·         Masking tape

·         Pliers and snips

·         Gloves and glasses

·         Cloth to clean up

·         Vice Jaws

Follow the step by step process for PTFE hose fittings.

1.       Cut the PTFE hose

2.       Fit the PTFE hose fitting socket nut on to the PTFE hose. 

3.       Flaring the braid

4.       Install the olive ferrule

5.       Insert the PTFE hose fitting right into the PTFE hose as you hose and push the hose end nipple into the tube with the help of lubrication.

6.       Engage the socket and PTFE hose into the fitting thread.

7.       Use oil and tighten the PTFE hose fitting into the socket nut.

8.       Get a professional finish by aligning the flats.

Try the above guide and see if you are able to install PTFE hose fittings with a professional touch.

Important Industries that Cannot Do Without PTFE Tubings

Industries today such as the steel Industry and chemical processing industry are making good use of  PTFE pipes or pipes made up of fluoropolymers for the carriage of highly reactive or corrosive chemicals. The pipes are used more and more substituting the use of pipes made of carbon and other metals.

The Properties of PTFE Tubes    

                                       

The PTFE tube properties are diametrical to the pipes of another kind of pipes. They have unique properties which help differentiate from carbon and other metal pipes. 

Thermal properties- PTFE tubing can withstand temperatures as high as 680 °F for a short duration under extreme cryogenic conditions; The material of the PTFE tubes does not change chemically even at high temperatures like 500 degrees Fahrenheit and can even endure cold temperatures such as -320 °F.

Electrical properties- PTFE tubing has some important electricalproperties as not only is it a great insulator but it boasts of great surface resistivity.

It is resistant to UV rays - PTFE tubing has other importantcharacteristics such as UV resistance and wearability.

Wear and Friction Qualities- PTFE tubing has a sort of slippery and smooth surface, and it has pretty impressive wear and frictional characteristics. 

Application of PTFE Tubes

• PTFE tubes are popular as it has pretty unique properties and can be used in a wide number of industries. The PTFE uses and Properties are as follows:
• In automotive applications, the property of PTFE which comes in useful is withstanding temperatures in excess of 250 degrees C makes and it makes an ideal high-temperature fluid transfer tube.
• In medical applications, PTFE tubing is used because of its lubricity and chemical inertness. For example the use of catheters.
• In chemical applications, it is used in laboratories and can specifically utilize glass tubes because of its inert qualities and also because it is very durable.
• In electrical applications, why PTFE comes in useful because it has effective dielectric properties of PTFE and it is suitable for insulating high voltage cables.
• Polytetrafluoroethylene (PTFE) is a high molecular polymer and the product is used in a number of cable and tubing industry because of its chemical inertness, electrical properties, and high-temperature resistance. The unique qualities of PTFE make it an ideal choice for a large number of industries. More and more industries are realizing the potentialities of PTFE tubing, and it goes without saying that PTFE tubes are and will be hugely popular and catering to the numerous demands of various industries.
