SPECIAL APPLICATIONS OF PTFE TUBING

PTFE Teflon tubing has remarkable non-adhesive property, and colloid and chemicals will not be adhered to the inner wall of Teflon tubing, so no dirt layer will be formed inside the pipe. Teflon is a highly non-polar material with electrical insulation properties and great resistance. Its dielectric constant is about 2.0, smaller than all the other electrical insulation materials, and changes in temperature and frequency have basically no effect on Teflon tubing.

Excellent aging resistance, radiation resistance and thermal stability allow PTFE tubing to be used in outdoor for a long time. Teflon has perfect non-inflammability and a limiting oxygen index of over 95, so it can only melt on the flame, but generate no molten droplets, and it has to be carbonized finally. It has high flexibility and good resistance to bending. Moreover, it has great resistance to moisture, so Teflon surface coating is not stained with water and oil, and solution is hard to be stained during production operation. A small amount of dirt can be removed by simple wiping. PTFE tubing has short downtime, thus saving working hours and improving efficiency. Next SuKo explains three special applications of PTFE tubing to help you make better use of Teflon tubes.

1. Resistance to high temperature, corrosion and high pressure
A Teflon Steel Braided Hose is made of special high-grade PTFE hose, high temperature resistant braided mesh and advanced stainless steel double-buckle spiral hose, so it is suitable for special environment of high temperature, corrosion and high pressure.
The hose can withstand 250°C high temperature steam inside under 3kg/cm2 air pressure, while the skin temperature does not exceed 60°C to ensure operational safety. It can be used normally under 10kg/cm2 steam pressure.

2. Light weight and strong softness
The specially assembled hose with a total length of 2m (including both ends of the joint) weighs only 500g, and can greatly reduce the workload of the operator. Its high softness and flexible bending will not obstruct the ventilation.

3. High resistance to vandalism
Advanced technologies are adopted in stainless steel double buckle self-locking spiral hose protection, so PTFE Teflon tubing can withstand 180kg of tension and will not be damaged during normal use.

EVERYTHING YOU NEED TO KNOW ABOUT PTFE RODS

 

What is a PTFE rod?

PTFE rods, also known as Teflon rods, are unfilled PTFE resin (can contain recycled PTFE resin) molded, paste extruded or plunger extruded for processing various gaskets, seals and lubricating materials that work in corrosive media and electrical insulation parts used at various frequencies. Plunger extrusion process to form the rod.

Main properties of PTFE rod

Operating temperature: from -200℃ to 260℃; easy processability; aging resistance: it can be exposed to ozone and sunlight for a long time without aging; corrosion resistance: it can withstand strong acids, strong oxidizing agents, strong reducing agents and various organic solvents except molten alkali metals and fluorinated media; outstanding electrical insulation properties.

THREE COMMON PROBLEMS WITH PTFE TUBES

 PTFE tube or Teflon tube, a semi-transparent, chemically inert and non-toxic material, has been mostly used in applications requiring resistance to high temperatures, including medical and health care, chemical, aviation, national defense, cutting-edge science and technology, and mechanical engineering, etc. One of its unique features is temperature resistance and its working temperature is from -190℃ to +260℃, so it can be used in elevated temperature applications which require high temperatures of over 200℃.  PTFE tubes have very good chemical resistance to common solvents, acids, alkali and bases, and excellent dielectric insulation properties.

Do you meet any problems when using a PTFE tube? Here SuKo Polymer Machine Tech Co., Ltd., a well-known China PTFE tube manufacturer and exporter, explains three typical problems to help you make better use of PTFE tubes.

1. How to connect PTFE tubes?

The continuous advancement of anti-corrosion technologies and innovation of anti-corrosion materials promote PTFE to be an attractive anti-corrosion material due to its excellent chemical stability, and high temperature and chemical corrosion resistance. But PTFE material has high lubricity and non-adhesive property, making it difficult to connect PTFE tubes. To solve this problem, hot air welding method and manual flanging method can be adopted to connect PTFE tubes.

2. Precautions of PTFE tube installation

The lined plastic is soft when drilling, but it is more troublesome to force a rigid drill bit, which will easily destroy the internal steel lined plastic pipe and cause edges to be hard to be flush, so it is recommended to use a cutter to open the hole. Lined plastic residues will fall into the original PTFE tubes during the hole opening process, so you should pay more attention during the operation, otherwise it will lead to blocked end water points. No electric welding tool should be used for punching holes or installing branch pipes, otherwise lined plastic of steel PTFE tubes will be destroyed.

3. How to treat the surface of PTFE tubes?

The surface of a PTFE tube should not come into contact with aggressive materials such as oil, solvents, and corrosive materials, etc. The surface should be cleaned with water and detergent and rinsed well after staining. The use of solvents and corrosive cleaning materials is prohibited.
You may encounter other problems when use a PTFE tube except these three problems, and don’t worry. You can find SuKo and will get necessary guidance and help.
