Korea Cast Iron Pipe

An environment friendly water and sewage pipe with an economic efficiency, sanitation security and coating performance through coating BPF epoxy powder at inner side of ductile cast iron pipe 1. BPF Epoxy Powder Coating • A powdered paint with substances like BPF epoxy resin, hardener, color, and additive • Ensures environment friendly, safety, and water quality sanitation by having none of the Volatile Organic Compounds(VOCs) 2. Coating Method • Applies an unique method with patented process in Korea Cast Iron Pipe Co. (4 patents on manufacturing technique) - Secures an excellent coating performance • Realizes a customer satisfaction for those who desire a clean water supply by having an equal thickness, elegant exterior, and beautiful luster

1. Reduction on a flushing cost after Initial installation Maximization of an effective use of water resource Efficiency on maintaining initial pipe conduit 2. Reduce electricity cost (Pumping Cost) Increase of an inner diameter ▶ reduction of head loss ▶ reduction on pumping cost 3. Reduce the transportation cost / Easy handling Weight reduction for pipe : 14.3% in case of DN300 Pipe Size (mm) Outside Diameter (mm) Weight of the Epoxy coated pipe (kg) Weight of the Cement mortalr lined pipe (kg) Reduced Weight (kg) 80 98 85.9 95.2 -9.7 100 118 104.1 115.6 -9.9 125 144 133.4 148.2 -10.0 150 170 160.7 178.2 -9.8 200 222 215.3 238.2 -9.6 250 247 281.8 310.2 -9.1 300 326 358.4 418.0 -14.3 350 378 442.9 512.8 -13.6 400 429 532.5 612.0 -13.0 450 480 628.0 718.4 -12.6 500 532 737.6 837.0 -11.9 600 635 973.7 1,092.4 -10.9
