HOW TO SELECT THE RIGTH HOSE

How to Select Right Hose.

In order to obtain the best service from any particular hose application, two important conditions must be fulfilled :

1. To select the right hose for the job.
2.To make sure, that after having obtained the right hose, it is fitted correctly and used in a proper manner.



When considering a particular hose application, the following basic factors should be considered :
1.  Inside diameter.
2.  Outside diameter.
3.  Materials being conveyed (e.g.,air,water,acids,oils,steam,etc).
4.  Precise composition of substance.
5.  Concentration.
6.  Maximum temperature of substance.
7.   Maximum Pressure.
8.  Degree of vacuum.
9.   External conditions. The scope of this factor is possibility the widest of all and covers such things as:
Abrasion.
Climactic Conditions.
Direct Heat.
Radiated Heat.
Contamination from oil, grease, solvents, acids, etc.
End Loads.
Flexing-degree and cycle.
Crushing conditions.
Kinking Conditions.
10.  Details of Couplings (particularly in specialized applications.)

Steam Hose

Air, Steam and Water hoses are the three types of hose most used in industrial plants. The following instructions apply in general to these types of hose. Since steam service is usually the most severe in the average plant, Particular attention is directed to steam hose. In selecting a hose for a steam installation it is important that the type recommended is sufficient to handle the maximum working pressure. Your Mithra Engineered Products representative will assists in marketing recommendations. At elevated temperatures, steam severely affects rubber hose of all types, so it is important that temperature be considered in the choice of a steam hose. In selecting a hose for a steam installation it is important that the type recommended is sufficient to handle the maximum working pressure. Your Mithra Engineered Products representative will assist in making recommendations. At the elevated temperatures, steam severely affects rubber hose of all types, so it is important that the temperature and pressure can cause detraction in certain reinforcing members used in hose and a relatively small increase temperature can greatly affect hose performance.


Air Hose.

Many fine types of air hose, equipped with tough, abrasion resisting covers and with are offered tube stacks which will successfully resist oil mist, if present. Where tools are lubricated through hose, only the very best quality air hose with highest grade oil resisting tube should be used. The recommended working pressure should be sufficient to with stand the maximum pressures encountered.


Water Hose

In the section of the correct water hose for any service, the same principles apply as for air and steam hose.


Suction hose

Most Sridhar Rubber Engineering Products vacuum or suction hoses are designed to with stand full vacuum. However, in some of the lighter styles, less than full vacuum is recommended.
