How to select a high pressure PVC hose
The airless spray hose is an important part connecting the pump body and the gun head. By pump pressurization, then passed through the high-pressure pipe and then sprayed onto the wall with the gun head, so the high-pressure pipe plays the role of transporting paint.
The high-pressure pipes of different lengths are used to meet the spraying construction at different distances, so it is inevitable that the pipes will be dragged, the gravel on the ground, and the construction residues will scratch it, and the high-pressure pipes should be avoided at corners or hard If it is in contact with any object, the pipe will vibrate during construction, which will also scratch the outer skin.
Now we have 2kinds of material airless spray hoses. one is with fibre reinforcement the other is with steel wire.
Fibre airless spray hose is made of PA12 and it has the characteristics of pressure resistance, heat resistance, aging resistance, corrosion resistance, etc. It has high pressure bearing capacity, excellent pulse performance, and it is soft to use and has little deformation under pressure.
The steel wire high-pressure pipe is made of steel wire and rubber. Its strength is higher than that of the fiber high-pressure pipe, and it has good fatigue resistance. But it is not easy to bend, so the construction is relatively laborious. Generally, steel wire high-pressure pipe can be used for latex paint spraying.
These are knowledge of the airless spray hoses do you get it?
