Our company plans to carry out pickling on its high-pressure and medium-pressure pipelines; does anyone here know the benefits of pickling, and exactly how much standard coal can be saved as a result? By how much can the purging time be reduced specifically? Where exactly is the difference between the cost of pickling and the cost of steam purging?
Regarding the fact that pickling can effectively shorten the purging time, it is generally not possible to calculate this directly for the question raised by the original poster; an estimate can only be made based on the effectiveness of the purging process
It is mainly to prevent corrosion of the pipes
I’m hearing this idea for the first time that pipeline acid cleaning can reduce purging time. In my opinion, the main purpose of acid cleaning is to remove impurities from within the pipes, such as rust, in order to keep them clean; it is mainly used for pipes carrying highly pure media.
The compressor lubrication lines must be pickled to ensure cleanliness, reduce oil waste, and prevent impurities from affecting the operation of the equipment； When the purity of the product is high, the pipes must be acid-washed; otherwise, it will affect the product’s purity ； It is recommended to perform acid cleaning followed by blast cleaning of medium-pressure steam pipes; this can save steam, reduce the time required for testing, and extend the lifespan of the turbine rotor.
