hand pump filter pipe

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.
