Product description: 
 PVC pipe drain is sanitary polyvinyl chloride (PVC) resin as the main raw material, adding the right amount of stabilizers, lubricants, fillers, hyperchromic agent by plastic extrusion machine extrusion and injection molding machine injection molding, by cooling curing, setting, inspection, packaging and other processes to complete the pipe, pipe production. 

 Product Features: 
 A pipe surface hardness and tensile strength superior, high coefficient of pipeline safety. 
 Two anti-aging properties, the normal life of up to 50 years. 
 Pipeline of inorganic acid, alkali, salts and excellent corrosion resistance, suitable for industrial discharges and transportation. 
 Pipe friction coefficient is small, smooth flow, clogging, less maintenance work. 
 5 high oxygen index, with self-extinguishing nature. 
 Pipeline expansion coefficient is small as 0.07mm / m. C, affected by temperature deformation is small. Thermal conductivity and elastic modulus is small compared to the excellent performance of anti-freezing and cast iron pipes. 
 Pipe, pipe connection can be used bond construction method is simple, easy to operate, install high efficiency. 
 Model: DN50mm-DN200mm
