What to do if the pipeline medium exceeds the flow velocity?
Thread Content
Since the diameter of the pipeline used for loading was designed to be too small (DN65), the loading speed was slow. Now, in an effort to increase the speed, a pump with a capacity of 50 cubic meters and a head of 32 meters has been installed; however, this results in a flow velocity that exceeds the acceptable limit, reaching 3.5–4 m/s. I would like to ask what precautions should be taken if the pipelines are not modified and loading continues in this manner. Could there be a risk of static electricity accumulation leading to an explosion? The medium is flammable and explosive ester-based products. The specification should be no more than 3 mi/S.
There is a danger; it does not meet the standards!
What was said upstairs is right; if nothing goes wrong, then there’s no issue. But once something does go wrong, those who don’t meet the standards will definitely be the first to be pulled out and killed
This definitely won’t work; one has to take responsibility if something goes wrong.
Which specification specifies a flow rate of less than 3 m? Please check. Loading 3-4m isn’t that unreasonable either
It’s best for the poster to check the regulations and follow them!
There are several bases for engineering design: 1. Regulations (such as fire safety regulations): Must be complied with. 2. Standard specifications: GB/HG/SYT: Recommended values (based on expert opinions, with a basis and safety considerations). 3. Owner’s specifications: Failure to follow them results in denial of acceptance. 4. Engineering experience: Although exceeding the flow rate may not necessarily cause problems, any issues that arise in the future will lead to accusations of not following the regulations. So, change the pipe diameter!
If there are regulations, they should be followed; after all, no one can afford to take that responsibility right now
