ABSTRACT
Field cleaning and degreasing of piping and ancillary equipment for oxygen service should not be considered as a separate project isolated from other considerations involved in the overall planning of the entire project. Field cleaning of the piping must be programmed to fit within the schedule of erection and construction of the pipeline in order to make sure that the cleaned pipe sections and the equipment are installed and erected immediately following cleaning. Unless a proper schedule is followed, cleaned piping and fittings may run the risk of being recontaminated by lying around with improper storage and handling, thereby defeating the very purpose of cleaning objectives.
