Handpumpe Filterrohr

hand pump filter pipe These pipes cutted by vertical technology,which is the most advanced cuttint of the world,and we are the only one who can master the technology . Material The PVC-U filter pipes for supplying water take the polyvinyl chloride resin as the main material, added appropriate auxiliary agent. It’s a plastic product by extruding and injecting, applied for supply system of construction. Advantage: (1).Light weight: weight in unit length is only 1/6 of the cast iron pipes. (2).Low resistance: the inner layer wall is smooth and prevents scum buildup. The water pressure and discharge of PVC-U pipe is 30% lower than cast iron pipes with the same diameter and can save the cost of discharge power. (3).Corrosion resistance: excellent resistance to corrosion that is caused by acids, alkaline, chemicals and electricity, therefore causing no stains. (4).Easy installation: connects easily with rubber rings. It is easy to install and seals well. (5).Long lifespan: under normal conditions the lifespan can reach up to 50 years. (6).Low cost: with lower cost of installation. Transportation and raw materials, the total cost of the engineering makes PVC-U 30% lower than that of cast iron pipes.
