We know that PTFE hose is the greatest among the plastic hoses. Because it’s nontoxic, odourless and because of the excellent chemical and corrosion resistance, it’s widely used in every industries. For example, PTFE is quite suitable for aviation because it has excellent chemical and oil resistance. But the quality in the market is uneven. This time let me introduce you how the high quality PTFE hose is produced. We take OrientFlex as the example.
OrientFlex take measures among all the production procedures to guarantee the top grade PTFE hose.
We purchase the high quality PTFE material from home and import the best raw material from foreign countries. Because we know it clearly that raw material determines the quality of hose directly.
The inner tube comes out from the extruding machine, then it will enter a PU duct hose. This is to protect the inner hose. Thus, it is immune to the dirty and dust in the air.
After the inner tube molding, we will take several tests to guarantee its quality. First is the air tightness test. Connect the hose into the test machine, then put into pressure, which is max 2.3Mpa. The pressure charge will last 10 second and remain the pressure for 1 minute. In the meantime, there will be figure on the machine. If the figure becomes small, that means the air tightness is bad. While if there is no change, that means the air tightness is good.
Another is air leakage test. Insert a steel rod into the inner tube, then use a special tool slip on the tube. If there is just small electricity between the tool and hose, that means there is not leakage. But if there is sharp reaction with fire, than means there is leakage on the fire point.
Besides, there are many other tests like insulation test, tensile strength test and cracking test. After these test, we can see the inner tube is high quality.
We set up a factory specially for PTFE hose. Because the quality will be guaranteed when we focus on it. These are the reasons why our PTFE hose is better than others. Professional manufacturer produce professional hose. Contact us now and get the latest information.
