On the formation and control of scarring

Pipelines and tanks are prone to scarring, mainly due to drops in temperature or prolonged accumulation of material; if you’re not bothered, remove the material once or clean them regularly.

If it cannot be removed naturally, manual removal is the only option. Have not experienced scarring; only dealt with cleaning sediment from storage tanks

What if scarring occurs very quickly and severely, for example, thick scars form within just a month? And it has to run continuously; it can’t stop and start from time to time.

There are ways to clean it up, but it’s too troublesome. What I want to know now is what methods can be used to reduce scarring or delay the appearance of scars, or what types of chemicals or equipment technologies might help.

I agree with you; this is indeed an issue that should be addressed through improvements in the manufacturing process

I agree with you; we should try to minimize the frequency of repeated repairs

Increasing the flow rate seems like a good idea! We’ve used it before as well; it can extend the time anyway!

Indeed, such devices exist; there are three methods in total: one is high-pressure water, the second is lasers, and the third is pretreatment. The first two both require maintenance time. The boiler scaling is much more severe than yours; it will take at least 8 hours using high-pressure water. Lasers are also fast, but their use is subject to certain limitations. Moreover, in both cases the core components are imported, which makes them relatively expensive, although they offer higher efficiency than manual methods. The third preprocessing method is the most economical approach. The approaches differ for pipes and tanks; this is actually a consideration specific to the metallurgical industry. For pipes, it is required that acid cleaning not be used, or that a special annealing process be applied after acid cleaning. It depends on the specific circumstances. Generally, in processing plants, protective atmosphere annealing is used only for tubes; if lasers are employed, it is not cost-effective to purchase equipment, so it’s better to rent it under a long-term contract. Thirdly, when the wind speed is appropriate, the problem of scaling can be completely resolved; however, if the process is not proper, it can only alleviate the issue rather than solving it fundamentally.

Thank you. Could you explain in detail the application scenarios?

Chat with me on phone; typing is too troublesome. The specific circumstances need to be clarified before a solution can be determined.
