We offer you experienced specialists in the field of operation, inspection, service and consulting of various types of fire-fighting equipment.<\/p>

In addition to the inspection of fire extinguishers, our comprehensive offer also includes inspections and services of hydrants and hydrant hoses. Such inspections should be carried out in accordance with the manufacturer’s recommendations, with a frequency of not less than once a year.

      It is important to regularly carry out pressure tests of the hydrant hose \u00d8 25.33 and 52 every 5 years. When establishing cooperation in the form of fire protection outsourcing with our company, you can be sure that we will take care of the timeliness of inspections for you.<\/p>

      We also carry out measurements of pressure and water efficiency in the hydrant network, which consist in connecting a properly assembled measuring set to the valve of the tested hydrant. When the shut-off valve is fully open, the static and dynamic pressure as well as the water flow are measured.<\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t<\/section>\n\t\t\t\t

      \u00a7 22. 1.<\/strong> The minimum efficiency of water intake measured at the outlet of the nozzle is:<\/p>

      2. for valve fi 33 – 1.5 dm3\/s,<\/li>

        \u00a7 22. 3.<\/strong> The pressure on the valve 52, located in the most unfavorable position in terms of height and hydraulic resistance, for the capacity specified in sec. 1 point 4, should not be less than 0.2 MPa.<\/p>

        \u00a7 22. 4.<\/strong> The maximum working pressure in the fire water supply system at the shut-off valve should not exceed 1.2 MPa, while at the valve 52 and the shut-off valves of hydrants 33 and hydrants 52 it should not exceed 0.7 MPa.<\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t<\/section>\n\t\t\t\t
