(1)DIMENSIONS:
The dimensions includes the hose internal and external diammetre.
The internal diametre is the inside circumference of the hydraulic hose.this inside circumference determines the hose size which is measured in inches or in milimetre. The smaller the size of the hose ,the higher the pressure of the hose. Also the bigger the size of the hose, the smaller the pressure of the hydraulic hose. The external diametre is the outside diametre of a hose. It is the body of a hydraulic hose exposed to weather or abrassion. The materials used on the external diametre are made to be tough inorder to make the hose withstand abrassion.so when you want to determine the right hose ensure that the measurement of the external diametre corresponds to the area by which the hose will pass through and the ability to withstand external heat and conditions. The diametre of every hydraulic hose is very essential most especially in the area where enough pressure are used.
2).LENGTH :
The area where the selected hydraulic hoses are to be used must be measured and crimped safely.
crimping involves the use of manual or electric device or machine to fit a hose.
Inorder to avoid joining two hoses together, an accurate measurement must be taken. Machines or pumps works very well when the hydraulic hose is at a straight length without any seam. Most hoses are measured in feets ,yards or in metres. In order to avoid any mistake,get your standard tape and study the accurate measurement.
A coil of hydraulic hoses normally ranges from 20 metres to 100metres length depending on the sizes.
3). MATERIALS TO BE CONVEYED:
material that are transfered from the hydraulic hoses must be clear to you whether they has any effect on the hose
. All hydraulic hoses are designed to convey hydraulics only and while oil hoses are used to transfer oil and diesel.Make sure that the hose material are made of good chemical compositions. Oil and hydraulic hoses are made of N B R(Nitrile butadiene tube) which has the ability to resist oil.
Both the tube and the cover can be made of the same chemical composition. Again,if you are using oxygen or gas ,ensure also that the hose you are using is comprises F P M(Florocarbon rubber materials. Then if your using the hose for fire fighting make sure its rubber composition is made of CHLOROPRENE OR ETHYLENE OXIDE. When the right hose is used for a specified use on hydrants it make it durable and also curbs environmental pollution.
