What to do if the top of an acidic water tank cracks
Thread Content
There is a crack on the top of the tank containing acidic water used in my installation; the crack is about 20 cm long and 3 cm wide. Welding is not possible at the moment. What methods can be used to seal it and prevent leaks? Please, fellow sailors, share your advice
You can hire an online leak repair company to seal the leak by drilling a hole and then applying a steel plate for bonding
If it is at atmospheric pressure, use acid-resistant adhesive for sealing.
We dealt with a similar issue last year (it wasn’t cracking, but corrosion); we had to address it in multiple locations on several occasions, as positive pressure inevitably occurs before curing, making things difficult to handle. 1. For the patch panels and the type of resin to be used, it’s necessary to find a professional installation company for this task. 2. Try to reduce the pressure until the material cures.
What material is used? Is it cured with asphalt?
It’s very simple: first, take proper personal protective measures to avoid hydrogen sulfide poisoning, then clean away the crystalline sulfides that have formed in the cracks; using Guolihao adhesive will do
1. As the original poster mentioned, the anti-corrosion coating on the inner wall of the pipe has failed, and the corrosion has caused significant thinning of the wall, posing serious risks. To prevent the hazards caused by ferrous sulfide ； When sealing leaks, a safety assessment of the construction work must be carried out; work can proceed only once appropriate measures are in place. 2. The adhesive method can provide temporary relief of the issues, but it is necessary to consider repairing the anti-corrosion coating inside the tank and strengthening the areas that have been thinned due to corrosion as soon as possible. 3. Apply the repair adhesive online and take proper protective measures. The adhesive application area must have all surface dirt and rust thoroughly removed; thereafter, the surface should be scrubbed clean with acetone before applying the adhesive. 4. The issue of slight positive pressure in the system has not been resolved; when sealing leaks with plates, it is possible to reserve threaded openings on the plates or install a small valve, which can then be used to block those threaded openings or close the valve once the glue has set.
Agree with the opinion above; should we consider adding stainless steel bandages around the entire tank at the leaky areas to protect the protective plates and to complement the effect of the adhesive?:)
What is the name and brand of the glue used? Is it available on the market?
