In the former article, I introduced you the classification of rubber hose in structure. Thus let’s learn how to classify rubber hose according to pressure and property.
According to the pressure, there are pressure resistant hose, suction hose and suction&discharge hose.
Pressure resistant hose
It’s used to transfer material in positive pressure, although the working pressure is higher than air pressure. With different materials and structures, the hose could be low, mid, high and ultra high pressure. While typical pressure resistance hoses are hydraulic hose and oilfield hose.
Suction hose works at negative pressure to suck materials like water. Normally, suction hose takes metal spiral wire or fibre as the reinforcement.
This kind of hose can not only transfer material in positive pressure, but also can suck material in negative pressure. Besides metal wire reinforcement, it normally has a armed structure outside.
While according to the property, there are normal hose, medium resistant hose and special hose.
Medium resistant hose
The hose should have great resistance to different materials. The most common medium resistant hoses are oil resistant hose and chemical resistant hose. While the typical medium resistant hose is composite hose.
Special hoses are classified according to their applications. Such as hydraulic hose for hydraulic system, brake hose for vehicle as well as acetylene hose for welding.
