Casing pipe is a type of steel pipe that is typically used to enclose and surround a carrier pipe, which is installed through the center of this pipe. Steel casing pipe is most often used in underground construction projects to encase or protect utility lines from being damaged. This pipe can be used when boring horizontally or directionally under roads, rivers, lakes, or railroads. In general, steel casing pipe is extremely durable and versatile, and therefore, it can be used in a variety of construction projects as well.Casing Pipe is available in a complete variety of different sizes and diameters as well as in straight seam, spiral-weld, and rolled and welded types of manufacture.
Uses for Casing PipeCasing pipe is most often used for underground boring to encase and protect pipe. During horizontal underground boring projects under streets, highways, railroads, rivers, and streams, steel casing pipe can be jacked in segments into an augured hole. The casing pipe segments are then connected together by welding or by using special connections. Another commonly used practice for installing casing pipe is to weld the pipe into a ribbon and then to pull the pipe directionally through a previously drilled hole. This can be used to install casing pipe under highways, railroads, lakes, and rivers.Casing pipe is most often used to protect underground utility lines including water mains, electrical high-voltage lines, natural gas lines, telephone lines, and fiber-optic communication lines. This steel casing protects lines from human activity such as drilling or digging as well as from natural elements. The strength of the steel is a major advantage to the protection of these lines.
