Fire hose couplings and nozzle are widely used in more an more areas nowadays in our society .
Fire Hoses are constructed from woven polyester internally lined with a synthetic rubber to give a smooth, low friction bore. This type of hose may be polyurethane coated to provide additional abrasion resistance. Other higher quality hoses comprise an all synthetic woven textile reinforcement encased in a PVC rubber which forms a unified lining and outer cover .
Fire hose couplings and nozzle should be put in at least one hose for each hydrant and these fire hose can be used only for fire fighting or fire fighting training .
Cargo ships of over 1000 gross tonnes must have one hose for each 30 m length of the vessel , plus one spare , but not less than five hoses .
In some case , the authority may increase the number of hoses required . The number of hoses required in vessels of less than 1000 gross tonnes will be determined by the Administration .
When we want to put the fire hose couplings , the fire hose couplings should be rolled from the center with both couplings accessible or flaked .
We should try our best to pay attention to the maintenance of the fire hose couplings and nozzle .
Fire hoses may chafe due to vibration, therefore they should be stowed with minimum contact with the locker interiors. Ideally their storage should be in dry, well ventilated conditions .
Avoid subjecting hoses to sudden shock loads by opening valves and hydrants slowly. Similarly avoid sudden closure of nozzles. After contact with oils and grease and after use with foam hoses should be washed and flushed through.
Drain and wipe down before stowing. To drain the hose lay it flat along the deck and under-run” it at shoulder height.
If a hose is kept flaked the position of the folds should be shifted when they are crumpled .
When we want to use to the fire hose couplings and nozzle , we should fit with the nozzle at the end of the fire hose and it can help people control the manner in which water is projected at a fire .
There are many various different of nozzles produced by our company can give people more chance to choose .
The fire hose couplings can be fitted with a nozzle so that can help the manner to be widely used .
If you have any problems about these fire hose couplings and nozzle , you can tell me and we can help you deal with the troubles .
