Catalytic start-up
Thread Content
After the start-up of the catalytic cracking unit, minor leaks occurred several times in the large pipes and large blind flanges used for light oil gases; the installation, materials, and equipment were all constructed in accordance with the specifications.
1. Whether there is stress in the pipelines during design and construction, or whether the operating temperature of the fractionation tower deviates significantly from the designed value. 2. Use wave-shaped gaskets, and try adding disc springs to the bolts. 3. The heat sealing must be done properly.
Where are the large pipes and large blind flanges for light oil vapors in a catalytic cracking unit?
I understand he is referring to the large oil and gas pipelines
It refers to the large oil and gas pipelines, two fractionation towers – one for light oil and large-scale oil and gas pipelines, and one for heavy oil and large-scale oil and gas pipelines
What 2# said is very reliable and can be used as a reference.
Wrap the area around the large oil and gas blind flange with a box, then apply glue there; leaks in that area can be very dangerous!
