Copper By Mandev Tubes

The GI has a relatively rough inner surface; so the pressure drop is fairly high when water passes through it. The right angle joints often used for GI pipes enhance this resistance of water flow. The copper tube ensures the minimal pressure drop-thanks to its smooth inner surface. Additionally the copper tube is bent smoothly towards any direction and the gentle curvature at the bending point offers little or no resistance to water.
Maintenance-free

Install it and forget it. That s the hallmark of copper plumbing. And that is why it is tailor-made for concealed installation in modern-day construction. A concealed GI pipe will have to be broken into when it gives trouble. Copper will hardly ever call for attention. Besides, the thin-walled copper tubing can be installed in narrow spaces, and being lightweight it is far easier to install. Copper is also immune to the external corrosion caused by concrete.
