Facts To Know Concerning Fire Hose Testing

By Martha Patterson


It becomes extremely necessary to keep the hosepipe always ready to perform its function. To make sure that this pipe is ready then it is absolutely important if you become familiar with it. Frequent maintenance is necessary since it helps in determining the defects of the hose pipes. There is usually a well laid out procedure that needs to be followed when carrying out fire hose testing.

One of the methods of testing is the hydrostatic pressure tests. Within this test, destructive test and non destructive tests are used. In conducting destructive trials, short specimens on the hose are used. In this case the hose normally undergoes destruction during such trials. The actual pressure which actually bursts the hose is recorded. When determining the weak point on the hose a hold test is recommended.

Non destructive method is actually useful if one considers conducting trials on the entire pipe. This is useful method since it reveals the weak points on the pipe which cannot be actually seen if naked eyes were used in examination. When using the specified pressure method, it is advisable to make sure that the hydro static pressure used in the trials is actually less than the pressure exerted above. It is actually advisable to regulate pressure so as to make sure that the deteriorating stresses which mostly weaken the pipe is managed.

Hold test is extremely important in determining or establishing the possibility of the pipe having defects in future. The length of the pipes being tested are recorded together with the amount of pressure being applied especially if the check up is conducted on braided wire.

In order to determine whether the pipe has the ability to withstand momentary pressure especially when sharply bent back then kink test is necessary. Test on pipes is actually beneficial. Firstly, such tests helps to reduce liabilities. Well coordinated tests actually reduces unnecessary liabilities both to the community surrounding and the department at large.

If there are any leakages associated with these components immediate repairs are advocated for. It is advisable not to use such a machine before repairing any damages associated with the machine. Before conducting the exercise one needs to make sure that the pressure gauge has been calibrated twelve months before the exercise is conducted. It is important to connect the test layout to the side outlet of water valve supply that is located on pipe of the machine.

The prior examination of these pipes is actually important since it would help in determination of any weaknesses which would result to future problems or which would erupt when the machine is at work. For any person to carry out the examination successfully training is absolutely important. Training equips the trainee on the basics and the procedure which is usually followed to conduct the entire process.

All other people whom are around the testing area are advised to clear from that scene leaving only the personnel who are conducting the exercise. The safety supervisor is required to issue all the personnel with a clear note before the actual process kicks off. Safety cones needs are placed in a distance of about twenty feet from where hose testing layout is being performed. Only the authorized staff whom are needed to be in that area where exercise is being conducted.
