Questions about steam

:Q: I don’t understand what Q:Q:Q means! ! !

Please refer to the specified purging section; there are requirements.

It’s not my area of expertise; I don’t understand what it means

What does \"targeting\" mean? Is it a form of suppression?

What is target shooting? I’ve worked in the chemical industry for so many years and have never heard of it. Is it some kind of colloquial term used in your area? Please explain it to me

The term “targeting” here refers to applying whiteboard paint to a wooden board during the purging process and placing it at the outlet of the purging pipe to capture impurities, in order to check whether all debris in the pipes has been removed.

This is the first time I’ve heard the term “target shooting”; we also do cleaning tasks, but it’s not that strict. It might be related to our manufacturing process.

It’s the first time I’ve heard that using steam for purging is called ‘target shooting’ :lol

Generally, purging is rarely continuous; it is intermittent. The purging time can be assumed for calculation purposes

There are standards in the pipeline installation manual; check it out

There is a corresponding relationship. Relatively speaking, the specific figures need to be checked in the manual. :)

Target shooting is generally carried out after 2 to 3 steam purges; only then does such shooting make sense.

Quote the original post: Question: For target shooting, are there any approximate values available for the diameter of the steam pipe, the amount of steam used for blowing, and the shooting time? ) Reply: Under normal circumstances, the pressure at the steam outlet is ensured to be sufficient to move the dirt; generally, this pressure is about 4–5 kilograms more. The targeting time should be 15–30 minutes or longer. The number of target hits depends on the process requirements of the equipment, and a score below the required level is considered acceptable. There are no strict requirements regarding the original pipe diameter for supplying steam. There is a corresponding relationship between pipe diameter, shooting time, and steam pressure, but no clear unified regulations yet exist. It is mostly based on experience. Blasting can also be used for purging.

Is the target plate parallel or perpendicular to the direction of the steam flow?

What is target shooting, and when is it done?

The target plate surface must, of course, be perpendicular to the steam flow direction.

"\"Target testing\" is merely a method used to check whether the pipes have been thoroughly cleaned during the steam purging process. The number of times such testing is carried out depends on the level of impurities on the target surface… It is necessary to determine whether those impurities are within the specified limits before deciding whether to continue with the steam purging process. The target surface must be perpendicular to the direction of the steam flow

The so-called target shooting involves checking, on the target plate at the steam outlet, the number and size of pits formed on that plate by impurities inside the pipeline. Then, it is determined whether the steam purging is satisfactory based on standards and experience.

I’ve learned a lot; it seems your standards are quite high

You mean the problem with the steam purge pipeline, right?
