The hose is made of a smooth, seamless PTFE tube. The PTFE tube of the hose is extruded under strictly defined and controlled conditions, which ensures its highest quality, minimal porosity and maximum possible for obtaining for hose smooth with PTFE flexible and flexibility. braid made is with annealed wire of steel stainless AISI 304 o high strength na stretching 1700 N/mm 2, o strictly controlled angle arrangement and voltage bundles wire braid, co results minimal changes length hose pod high pressure. double braid whereas, should use at higher pressures and tam, where available (in permissible limits) greater bending or kinking hose. Due to the unique properties of PTFE (large operating temperature range, resistance to most substances and chemical compounds, negligible adhesion surface) hose SMOOTHBORE perfectly is suitable for conveying substances chemical, food, fuels, oils, paints, solvents, adhesives, dyes, detergents, steam water itp. – as well as for classic high-pressure hydraulic oil installations. W case when identified is hazard electricity static (danger formation and accumulation charges electric), should use hoses SMOOTHBORE made with PTFE antistatic – version antistatic AS. antistatic teflon version AS is black (contains appropriate distributed in PTFE carbon) and has resistance R 8 Ω (in accordance with the standard ISO 8031 anex A). ensures to discharge and dissipation (dissipation) charges electric. Safety factor 3:1; if a factor of 4:1 is required (np. acc. to EN 16643) should multiply values through 0.75. at temperature use above +130°C maximum pressure working given in parameters should reduced o 0.75% na each 1°C above tej temperatures. for example at temperature 170°C maximum pressure working for hose AF-SWDB-08 is: 250 bar – (170°C-130°C) x 0.75 = 250 bar – 30% = 175 bar. The value “Wall thickness” given in the Technical data refers to the PTFE layer. Material hose: smooth PTFE (teflon). Reinforcement: double braid of steel AISI 304. pressure working: from 70 bar to 360 bar – depending on diameter hose. temperature use: from -70°C to +260°C.
