How to solve the problem of thermal insulation and anti-corrosion of oil pipelines
Thread Content
There is a 100-kilometer long-distance pipeline in Shandong. The medium is residual oil. The temperature requirement is 70 degrees. It is buried underground. The anti-corrosion method is polyethylene cold-wound tape. What kind of material is used for insulation and can best be combined with the cold-wrap tape? Or provide some solutions that you think are good. Waiting online, thank you,
Insulation rock wool is a soft insulation material, right? Do you have any relevant cases or achievements of polyethylene cold-wrap tape and thermal insulation rock wool for anti-corrosion and insulation?
The rock wool is foamed and then covered with iron sheets. Anti-corrosion brush can be used during high temperature period
The temperature is 70 degrees, so 100 kilometers is correct. Have you calculated the temperature loss? Even with the best insulation, it goes in at 70 degrees, and I don’t know what the temperature is when it comes out after 100 kilometers (you can guess). Once the residual oil cools down, it becomes very viscous. I think insulation alone is not enough for the second pipeline. It should be heated.
