Steel Pipe Rehabilitation
Most pipelines have some sort of coating. If proper procedures are undertaken, the coatings can be removed on location or the removed pipeline can be transported to a cleaning yard. Responsible recovery crews are environmentally certified and educated to handle coating waste in case the coating turns out to be hazardous.
After the coating is removed, the pipe is checked for bends, bows, dents, and dings. Roundness and straightness is also to be ascertained. Pipe should be separated at this stage to determine the better pipe that might be ready to ship to a customer or that might need additional attention. No matter how competent an operator might be, damages will occur, and externally the pipe can be dented or dinged with the track hoe forks or shoe during the removal process.
Sometimes the pipe could be bowed intentionally when laying and need to be straightened. Customers want round and straight pipe, and it is much more economical to load and transport straight pipe. Beveling of each end where the pipe was cut during removal is necessary if the pipe is to be re used as line pipe. Some pipeline recovery crews may be able to rehabilitate excavated pipelines at the removal site by using portable de-denters, pipe straighteners, beveling machines. It is best to reduce the trucking and handling of the pipe as much as possible and perform pipe rehabilitation on-site. Otherwise, there are pipe service yards in various parts of the country that have the expertise and equipment to handle most jobs. If the pipe coating has not been severely damaged beyond repair, the pipe will go directly to a coating facility or threading facilities depending on the intended use for the excavated pipe.
