[Composite Repair Case Study] Repairing Pipe Thickness Without Stopping the Plant!
Restoration of strength, leak prevention, and corrosion protection effects of reduced meat piping! Case studies of composite repair services.
Corrosion occurred on the 8B piping laid on the upper part of the tank in the oil refining plant, and according to the RT results, it was found that the minimum wall thickness of the 3/4B boss section is 0.6mm. In the event of a problem with the piping, there is a risk of leakage of the internal fluid (butane), and to update the piping, the entire plant must be stopped, making corrosion prevention measures essential before any leakage occurs. Therefore, as a corrosion prevention measure centered around the boss section, a composite was laminated in two layers over a range of 300mm to the left and right of the 8B main pipe. The high environmental barrier effect of the composite layer completely prevents the progression of external corrosion and reduces the risk of leakage compared to measures taken with just anti-corrosion paint. [Effects] ■ The high environmental barrier effect of the composite layer completely prevents the progression of external corrosion. ■ The risk of leakage is reduced compared to measures taken with just anti-corrosion paint. *For more details, please refer to the PDF document or feel free to contact us.
basic information
【Case Summary】 ■Measures - Composite materials were laminated in two layers for corrosion protection in a range of 300mm to the left and right of the boss section of the 8B main pipe. ■Construction (2 people for 2 days) - Shaping - Surface treatment - Lamination of glass fibers and carbon fibers - Curing confirmation ■Construction Points - Carbon fiber, despite being about a quarter the weight of steel, has a strength approximately 10 times greater and a hardness about 7 times greater, making it an excellent material with the characteristics of being "light and strong." - Not only is the transportation of materials easy, but it also poses no concern for load when laminated on reduced-thickness piping installed at heights (without support) due to its lightweight nature. *For more details, please refer to the PDF document or feel free to contact us.
