Flexible Metal Hose For Fire Sprinkler Connection Fire special metal hose on conventional heat-resistant tube adopts the new type of equipment and the metal layer, as a fire hose and heat-resistant conductor, its material can be up to a few microns, even with a few microns in diameter and is larger than the surface, the advantages of filtering less resistance, to solve the internal heat conduction problem such as restricted by material itself. Tiny material characteristics, greatly increases the heat dissipation on the surface of the material to the surface of the product and freedom, increase the heat transport fast and the temperature of the material are scattered ability level, so as to improve the efficiency of heat transfer and heat conduction coefficient and rate.
