Do the temporary pipelines installed during the oil flushing of the lubricating oil system need to be pickled before starting the actual oil flushing?

Regarding the temporary pipelines used to connect the inlet and outlet of the external flushing unit during the lubricating oil flushing process, are these also to be welded using stainless steel TIG welding? Is it necessary to carry out acid washing first? The construction party does not intend to do so in order to save time, planning to weld them on-site right away and then proceed with the oil flushing
Pickling is done to remove scale and impurities; to avoid unnecessary trouble, it’s advisable to carry out pickling!
Pickling is done to remove the oxide scale formed in the air, thereby creating favorable conditions for the subsequent passivation. To ensure the corrosion resistance of stainless steel, good efforts have been made
It’s mainly temporary pipelines; acid cleaning is not considered necessary – they are welded directly and then subjected to oil flushing
Even if it doesn’t need to be washed, debris still needs to be removed. If it’s not cleaned, is there a filter in place? Generally, a temporary filter can be installed at the end of the temporary pipeline~~
