The tubing material is as important as the size of the connection. Silicone is soft and elastic, so it can provide a small inner diameter for larger connectors. Minimizing the dead volume can be helpful. The tube is not adjusted. That is, when it is unplugged from the connector, it returns to its original size. However, the silicone rubber is slippery and easily detaches from the connector, and therefore, it is insufficient as a material for frictional assembly.
Polyethylene is rigid and does not stretch on the connector, but it will be well connected first. However, over time, the EP needs a lot (expanding forever) and weakens the connection. KP-LOK
Polyurethane has good stretch and adhesion. If you try to pull a PU tube that fits the connector, it stretches like a Chinese finger trap and catches more of it. Removing the plug may damage or remove the tube. Polyurethane is an excellent material for friction fit connection and we are the only material recommended for subcutaneous connection.
Working pressure and temperature of the hose.
Every pneumatic tubes manufacturer offers some very important parameters to choose from. This is the pressure value when the tube is working. By describing the working pressure and temperature you can see the temperature and pressure value of the pipeline for a long time.
Under normal conditions, the operating pressure is 4 times lower than the burst pressure, so that the pipe is absolutely destroyed. Both parameters are given at a specific temperature of 23 ° C for KP-LOK company pipes.
Such a safety measure means that even if the controller accidentally breaks down, the hose will not be damaged. But do not forget to use the operating temperature and the pressure of the pipe instead of the maximum pressure.
Exposure to different fluids
In order to achieve reliable performance and a long service life, it is important that the tubes are resistant to the chemicals they are exposing to. The best advice is to understand the chemical resistance of the hose and always test in real conditions before actually using it.
In pneumatic tube applications, lubricating oils can attack some components over time. In addition, corrosion in the outside of the pipe can be caused by liquids, solids, or gases. In rare cases, the compressor can detect substances that attack the identification of the tubes. In industrial fluid handling applications, the material of the transfer tube or pipe is usually the most important.
A good starting point is the chemical resistance chart provided by many manufacturers. However, please note that this information usually comes from chemicals and resources used. If you are concerned about the compatibility of chemicals and substances, use only general reference guidelines to limit the selection of potentially relevant products. This is because the presence of temperature, environmental conditions and other chemicals can have a major impact on the chemical resistance of the pipe or tube.
Resistance to attack
The characteristics of this broad category of tubing are mainly focused on exposure to the environment or working conditions. In addition to the usual chemical resistance above, it also includes flammability, moisture, ultraviolet rays, abrasion, vermin, kinking, bacteria and fungi.
These often neglected environmental factors can cause premature rupture of the fetus. If an application can cause serious damage or damage in the event of a breakdown, careful selection and rigorous testing must be done.
If two or more pipe connections are available for this application, the pipe cost will affect the measurement results. However, in terms of equipment damage, personal injury, production loss, maintenance time and costs, the cost of unplanned outages in most cases far exceeds the cost of the tubes. The pipe is a relatively cheap item; its real value is a long term and maintenance free life.
