The PVC drain pipe produced by plastic pipe production line has a relatively long service life

         The PVC drain pipe produced by plastic pipe production line has a relatively long service life.the PVC pipe has high chemical resistance and indissolubility, the size standard is stable, the wall thickness is uniform, withstand high pressure, flame retardant and high strength, the wall is smooth, friction is small, not scale, high transmission efficiency, long service life, about 20-50 years.

          PVC plastic pipe production line is made of sanitary grade PVC resin as the main raw material, with an appropriate amount of stabilizers, lubricants, fillers, coloring agents, etc., injected by plastic extruders and injection molding machines, and through cooling, curing, finalizing, inspection, packaging and other processes to complete the production of pipes and pipe fittings.

          PVC plastic pipe production line how to identify the product material.To see whether the specified wall thickness is reached, another point should be noted here. Some pipes are evacuated pipes, and the wall thickness at both ends meets the requirements, but the middle and middle wall thickness is relatively thin, which fails to meet the requirements for use. Meanwhile, the cost can be reduced by means of pumping.To see whether the specified length has been reached, some manufacturers reduce the price by shortening the length.According to GB/ t10002.1-2006, no negative deviation is allowed.Those with a glossy surface that looks oily are of superior quality.The standard quality pvc-u pipe is light beige, if the pale pipe that calcium powder added to excess, some manufacturers add more miscellaneous materials, recycled materials, made of pipe black, yellow.Take the same caliber, wall thickness, length of the two pipes to compare the weight, the weight of the calcium powder, impurities added too much, the material is not pure, can not meet the requirements.



          PVC drainage pipe plastic pipe production line is mainly composed of double conical (parallel) screw extruder, vacuum calibration tank, tractor, cutting machine, tilting machine and so on.The screw extruder and traction device adopt imported air conditioner inverter, the barrel and screw are treated with hard chromium plating and bimetal treatment, which effectively reduces the wear of CaCo3 and other additives.Vacuum pumps and drive motors are used in excellent products.
