Why Should One Choose Steel Pipes Over Ductile Iron Pipes?
While ductile iron and steel pipes both look similar, they do have their own unique advantages. Listed below are a few of these advantages. If you're thinking of installing a new water main in your home or business, steel pipes are a great choice. They are durable and can withstand a wide variety of stress levels, including bending and longitudinal stress. Unlike steel pipes, ductile iron pipe joints are 18 to 20 feet long. This means that installation is easier and faster. Four joints of 24 inch ductile per hour equals 72 feet of pipe. By comparison, it takes about four hours to install one steel joint of 40 feet. In addition, an 18-foot DI joint can deflect more than a 40-foot steel joint, minimizing the number of fittings required and lowering the overall cost. Steel pipes are much harder than ductile iron and can be subject to abrasion. In addition, ductile iron is more resistant to corrosion. Both ductile iron and steel pipes have different corrosion mechanisms. With a ductile...
