Apparatus and method for cleaning the inner surface of a pipeline from deposits and for forming a protective coating are disclosed. The apparatus includes a cleaning tool which is caused to move in the interior of the pipeline by a flow of a fluid, the cleaning tool comprising a plurality of guide discs engaging the pipeline surface and mounted along a longitudinal axis of the cleaning tool, an anode positioned inside the cleaning tool, and an impressed current source electrically connected to the anode and the interior of the pipeline, the interior of the pipeline acting as a cathode when current is applied from the current source so that ions flow from the anode, through the fluid, to the interior of the pipeline.

An irrigation pipe and method of fabrication that utilizes a pipe that is made of a durable material, e.g., stainless steel or aluminum. During fabrication, the pipe is equipped with a plurality of components, i.e., a flange assembly, a truss mount, and an outlet, without drilling, welding, or the like. In this manner, a method of fabrication is provided that enables a plurality of components to be assembled to the pipe without compromising the integrity of the pipe material or treated surface so that galvanizing or painting is not required after the plurality of components have been fitted to the pipe.

A tubular structure is disclosed. The tubular structure has a first sheet metal having a machine direction. The first sheet metal is convolutely wound about a longitudinal axis and has a tail portion. The tail portion of the first sheet metal is disposed upon and bonded to an immediately subjacent convolution of the first sheet metal.

An elongate tubular structure is disclosed. The elongate tubular structure has a first and second tubular structure wherein a first end of the first tubular structure is matingly and fasteningly engaged to a first end of the second tubular structure. The first and second tubular structures each have a first sheet metal having a machine direction being convolutely wound about a first longitudinal axis. The first sheet metal has a tail portion that is disposed upon and bonded to an immediately subjacent convolution of the first sheet metal to form the respective first and second tubular structures.

Processes and systems for preparing pipe for machine processing to form pin and box ends for assembly into pipelines using mechanical press-fit pipe joints that are fully measured and documented during both manufacturing and assembly. Installed pipelines include pipeline data monitoring systems coupled to a pipeline data management center for receiving, archiving, and analysis of the data records to aid in administration, operation and management, and troubleshooting of pipelines.
