- Original production string acidizing is a new technology, which can greatly shorten the recycle of acidizing treatment and economize operating cost.
- The stainless tubing is less likely to kink than copper, but it is harder to solder without an acid treatment.
- Remaining alkali may be neutralized with a cold acid treatment followed by several more rinses to remove the acid.
