How to monitor the residue in the pipeline?
What kind of liquid is the so-called residual liquid? First, it’s necessary to know whether it is easy to evaporate If the temperature is below minus 100 degrees and there is residual liquid in the pipes, natural heat absorption will cause it to evaporate, resulting in an increase in pressure, which indicates the presence of residual liquid. Pre-monitoring can only involve checking for drainage through the guide pipes, to see if there is any process fluid or process gas being discharged
A pipeline monitoring system can be used. A pipeline monitoring system generally consists of three main components: a control center, remote transmission channels, and monitoring terminals. Its control method is determined based on the pipeline transportation process; for example, multi-level distributed control is widely used in long-distance pipelines. Its structural approach depends on the way in which the remote transmission channel connects the dispatch center and the monitoring terminals, with the main types being one-to-one, one-to-many, and hybrid. If it is just a regular pipe inside the device, a drain line can be used.
What does the original poster mean? Is it necessary to prepare the pipeline for welding?
Do you mean the residual liquid in the hoses or loading arms used for loading and unloading ships or vehicles? ? ? ? ? ? ? ? ? ? ? ? ?
