Fire hose is used to transport such as high pressure water or foam fire retardant liquid hose. But how much does a fire hose weigh? Also according to its material is different. The traditional fire hose with rubber lining, outside surface wrapped in linen woven fabrics. Advanced fire hose is made of polyurethane polymer materials such as. The two ends of the fire hose has metal joint, can be connected to another hose to extend from or connected to the nozzle to the increase of liquid jet pressure. Below we through classification to find out how much does a fire hose weigh.
Fire hose divided into two categories, with lining and without lining. Lining fire hose including cotton, nylon line, polyester filling glue, glue hemp qualitative plastic coated hose. No lining hose water hose with cotton, flax, ramie hose. According to the work under the pressure of 0.8 MPa, 1.0 MPa, 1.3 MPa, 1.6 MPa four classes. According to the diameter is divided into 50, 65, 80 or 65, 90 mm four classes. According to the weaving method divided into two categories, twill plain hose and hose. Each water saving with the length of the general rules for 20 meters. If there are multiple specific to weigh how much does a fire hose weigh, may be is not to say. Because the material is different, the weight is different.
Sometimes, also need to test for fire hose, can preliminarily concluded that fire hose decided that how much does a fire hose weigh. When inspection in the same variety, same diameter, hose for a batch of 1000 meters long. To randomly from 100 meters to do visual inspection. In the most economic way to capture 3 sample, the sample length should comply with the rules. 2, the inner diameter of the sample should both comply with the provisions of this standard; Three sample weight per unit length and ShenShuiLiang arithmetic mean shall comply with the provisions of this standard; A sample only a state of blasting experiment was carried out, and shall comply with the provisions of this standard. 3, check if there is a is not in conformity with the provisions of this standard, allowing the re-inspection again. While the reinspection do not coincide with the most economical method of double extraction sample. Sample the result of the reinspection shall be in line with the provisions of this standard, or for the nonconforming product. 4, when the supply and demand both sides disputed the quality of product, all arbitration inspection fees shall be borne by the responsible party.
