This single jacket 600lb. proof test Forestry Hose is designed for use with portable gasoline/diesel pumps, heavy duty Fire Engine Tankers and Pumpers. Light in weight, this hose is made to be transported by air, man-packed or by animal for long distances over steep and rough forested areas. All components of the hose system shall be fabricated from mildew resistant material permitting storage over extended periods of time in damp areas without concern for degradation or deterioration. All components shall be made in the USA.
The fire hose to be supplied under this specification is a premium quality, single jacket forestry fire hose. All materials used in the fabrication of the hose shall be of the best quality commercially available. The manufacturer shall be ISO 9001-2008 Quality Certified.
The 100% synthetic warp yarn shall be virgin fiber domestically produced to be free from defects, dirt, knots, lumps and irregularities of weave as is consistent with quality manufacturing. The filler yarn shall be all polyester filaments, high strength material suitable in all respects for the manufacture of high quality fire hose. The jacket shall be constructed using a twill weave design to reduce friction loss and increase gallons per minute (GPM) flow due to the water way being smooth. Traditional square weave design is Not Acceptable and will be cause for the hose to be rejected.
The thermoplastic lining shall be a single-ply extruded tube, compounded to reduce deterioration by ozone. The finished form shall be free of pits or other imperfections and shall have a smooth finish. No reclaimed material shall be used. The thickness shall not be less than .016” nor greater than .020” for the 1” hose and not less than .018” nor greater than .022” for the 1-½” hose. Tensile Strength not less than 1200 psi Elongation not less than 400%. Adhesion shall be such that a 12 lb. weight shall not move a 1-½” strip cut transversely at greater than 1” per minute.
Each length of hose shall be capable of a hydrostatic pressure of 600 psi for fifteen (15) seconds, without leaking in the hose or at the couplings or breaking any yarn in the jacket. Burst of a 3 ft. specimen selected from every 5000’ shall with stand without failure a pressure of 900 psi, or three times the Service Test Pressure of 300 psi while lying straight or curved to a radius of 27”. Kink pressure shall be such that a random length of every lot of 2500’ shall withstand without failure a hydrostatic pressure of 450 psi, or 1-½ times the Service Test Pressure of 300 psi while in a kink condition.
Hose Length and Diameter
The hose shall be available in nominal 50 and 100 foot lengths. The hose shall have an inside diameter of not less than the trade size of the hose.
Hose is available with internal expansion ring anodized aluminum couplings with NH, NPSH, or Quarter Turn couplings, meeting U.S. Forestry specifications.
The manufacturer warrants the hose to be free from defects in materials and workmanship for a period of one year. This warranty shall provide for the repair or replacement of hose and couplings proven to have failed due to faulty material or workmanship
