Pipe (plate 2A) is a common product that we use for the supply of water in our household work. PVC (plate 2B) material produces large varieties of flexible pipes that are commonly used for the garden water supply. Using Terra-cotta pipes (plate 2C) for smoking is found from the ancient period around the world. Smoking pipe is designed based on the principle of natural passage found in many plants. Corrugated pipes (plate 2D) provide flexible passage for the supply of gas or fluids.
