Concrete Steel Cylinder (RCCP)
Definition - What does Concrete Steel Cylinder (RCCP) mean?
A concrete steel cylinder is a concrete pipe that is reinforced with a steel cylinder, which consists of a concrete inside diameter, a steel cylinder mid-section and a concrete outside diameter. The concrete layers help protect the steel from corrosion and provide additional mechanical advantages.
A concrete steel cylinder is also known as a reinforced concrete cylinder pipe (RCCP).
Corrosionpedia explains Concrete Steel Cylinder (RCCP)
Concrete steel cylinders are comprised of a steel cylinder with a layer of concrete on the inner diameter and the outer diameter. They are large in diameter, the smallest typically being around 760 mm (30 inches). However, smaller diameter concrete steel cylinders do exist.
Several steps go into making a concrete steel cylinder. First, coiled steel must be welded together. This is typically done using the submerged arc welding process. Once the steel cylinder has been welded, concrete is poured around it. To do this, the steel cylinder is placed upright with concrete forms placed around it. Concrete is then poured into the forms and allowed to set. This is commonly done by a vertical concrete casting method.
Concrete steel cylinders are used to transport fluids in a variety of industries. Irrigation is a popular application for concrete steel cylinders, as is wastewater and sewage. Concrete steel cylinders can be used to create inverted siphons. Piping systems that need to be submerged in water are also sometimes made out of concrete steel cylinders.
