Tips: Application of paperless chart recorder in pipeline pressure test project
In the pipeline construction in the petrochemical field, a pipeline pressure test must be carried out before going into production. In particular, the pressure test of pipelines in the construction of ships and platforms requires the use of a pressure recorder to record the curves during the pressure test for inspection and archiving. Previously, the disc pressure recorders were used on-site mostly. This recorder is large in size, high in cost, high in maintenance costs, and easily affected by field factors to cause interference and time lag. After changing to a paperless recorder, the pressure data is accurately reflected on the computer, which can be stored for a long time and can be processed, viewed, and printed at any time. Thereby improving the work efficiency of the pressure test and promoting the overall progress of the pressure test project. The installation of the paperless recorder can keep the pressure testing personnel away from the pressure testing pipeline and increase the personal safety of the pressure testing staff. In terms of economic benefits, the cost savings of a paperless recorder compared to a disc recorder are the cost of the recorder itself, maintenance cost and the cost of thermal paper. At the same time, because the recording of the paperless chart recorder and the on-site pressure meter are synchronized, the pressure test time can be effectively increased by 1 hour. In this way, nearly 3,000 working hours can be saved in one year.
