PVC-U water pipe product features lightweight, convenient transportation and handling: PVC pipe material is very light, convenient transportation, handling, construction, saving labor. ● excellent chemical resistance: PVC pipe has excellent resistance to acid, alkali, corrosion resistance, for the use of the chemical industries. ● fluid resistance: PVC pipe wall of smooth, fluid's resistance, its roughness coefficient is only 0.009, lower than other pipes in the same flow, the diameter can be reduced. ● the mechanical strength: PVC pipe the water pressure resistance strength, pressure-resistant strength, very good impact strength etc., suitable for various conditions of the piping works. ● Good electrical insulation: PVC pipe full of excellent electrical insulation for wires, cables of the catheter, and wire construction on the pipe. ● does not affect the water quality: PVC pipe by dissolution does not affect the water quality tests confirmed, is currently the best of the pipe water pipe. ● Construction Simple: quickly and easily bonded construction of PVC pipe, so the low cost of construction projects. PVC-U water supply pipe project PVC-M product parameters to PVC-U pipes for irrigation pipes PVC-U tube density / (kg / m3) 1.35-1.46 1.35-1.46 1.35-1.55 Vicat softening temperature ≥80 ≥80 tensile yield stress / Mpa ≥40 Longitudinal reversion rate% ≤5 ≤5 ≤5 flat test no rupture without rupture no surface rupture methylene chloride immersion test 30min 15min No change No change surface drop hammer impact test TIR≤5% TIR≤5% 9 / 10 through the high-speed impact test hydraulic test brittle damage does not occur without rupture, no leakage, no rupture, no leakage, no rupture, no leakage of hydraulic pipe notch test no rupture, no leakage C- ring ductile failure of long-term static toughness test σLPL≥24.5 pressure test performance standards CJ / T272-2008 GB / T10002.1-2006 GB / T13664-2006 PVC-U water supply pipe superiority ● Excellent toughness and impact resistance: with the same specifications of the ordinary PVC-U pipes phase ratio, significantly improved impact resistance, can more effectively resist point loads and uneven settlement of foundation. ● anti-water hammer performance improvement: You can effectively resist water hammer, to prevent pipeline damage in the operation process. ● resistance to environmental cracking performance improvement: effective against installation and transportation of external shocks on the pipe. ● improve transport reliability: PVC-M high impact to overcome the ordinary PVC-U water pipe, subject to wear, nicks in the handling, transport, internal injury resulting pressure drop characteristics, can effectively resist external shocks, improve transportation reliability, security. ● improve the construction environment adaptability: PVC-M high-impact water supply has excellent impact resistance and good toughness, can effectively adapt to the construction environment. PVC-U water pipe construction side made a connection TS cold, pipe end should be smooth and perpendicular to the axis; the male pipe end cut along the outer corner of 30-45 degrees, set aside 1 / 4-1 / 3t thickness of the pipe end. 2, pipe socket wall and the outer wall of the pipe end is inserted into the range, wipe clean with alcohol or a dry cloth, draw insertion depth marks, apply the right amount of glue, brushing should be quickly and evenly, the amount shall be applied to the drain. 3. Insert the tubing into the socket, firmly insert the pipe to a depth mark previously set aside a small diameter pipe rotated 90 °, large-diameter pipe into usable mallet strike, the extruded adhesive wipe clean. 4, pipeline installation, only need to pass water 48 hours after the pressure test, pressure test the pipeline distance should be the best in the 400m-500m. Looper construction method 1, the male pipe end 20 ° cut along the outer corners, the thickness of the pipe ends to reserve it as 1 / 4-1 / 3t. 2. Wipe the rubber ring and groove Looper, will follow in the big rubber ring into the groove Minor. 3, the length of the male pipe end is inserted marked and set aside some space. 4, in the male portion of the tube end into the inner surface of the sleeve and the ring smear lubricant. 5, male and female pipe socket. 6, after the socket is completed with a sheet test whether Dingfan apron.
