What does this pipe look like?
Thread Content
These sections of fluorine-lined pipes have been installed, but I always feel that something is wrong. Could you please give me some pointers as to what is wrong and what standards should be used to explain it: handshake
Let me guess: Jumpers, color codes, supports
Is it okay to put it directly on the ground without pipe support? I don't think so

Safety-related on-site obstacles also involve anti-corrosion, possible anti-freezing and thermal insulation,,,,. Check this on the construction drawings, it shouldn't be like this. There is a problem with on-site supervision. Oh, and the distance between the lower outlet of the discharge valve and the ground should be set up with a trench. I don’t know if this jar belongs to me * * It belongs to the regulatory department, otherwise it is necessary to set up pipe trenches.

I will make a comprehensive diagnosis because if it is hydrocarbons, liquid chlorine, ammonia, nitration products, vinyl chloride, phosgene and other key hazardous chemicals, special control and inspection methods will be upgraded.
It is still recommended that Haiyou use standard specifications for analysis, and analysis without standards. I think it is "talking nonsense" and is not conducive to everyone learning from each other.* :lol
I have never seen talents put directly on the ground like this.
This medium is not complicated, and it is precisely because of this that the owner went through a simple change process and then modified it by himself. The design and installation were completely irregular. :lol This storage tank can be regarded as a wastewater recovery device. The recycled water contains trace amounts of chlorination reaction organic matter (such as trichlorethylene, tetrachloroethane, etc.). The amount is not large, but it is not easy to treat the discharge. In addition, this part of the recycled wastewater can be used to produce acetylene in the device, which is no problem at all. It can also be regarded as solving the environmental protection problem and killing two birds with one stone. The old moderator checked the specifications to see which requirements were not followed: handshake
In the second picture, the protection for the rotating parts of the pump is still missing. Trichlorethylene is flammable and involves electrostatic bridging. It is more troublesome to lead out pipelines lined with PTFE. If the lining is thick, it will not be lead out, and if the lining is thin, it will be damaged. If the area is flammable or toxic, a flammable and toxic alarm device is required.
Is this a section of the pipeline where the lower part is poured directly? There are many missing ball valve handles at the pump\ud83d\ude04
