Anticorrosion of saltwater tanks

In particular, are there any specific requirements regarding the lining of saltwater tanks? What standards must the technology meet? # + + .
For anti-corrosion inside brine treatment equipment, rubber lining or epoxy glass flake lining is generally used; although these are two different methods, in both cases sandblasting is required to achieve a rust removal level of Sa2.5
Reply to 1# Green Uniform Dream: It is difficult to apply rubber lining to salt water tanks, as these tanks are large in size and make it hard to carry out rubber vulcanization; it’s better to use glass flake lining instead.
But this one is just lined with rubber; it doesn’t need to be vulcanized, right? Is it the long service life of the epoxy scale coating, or that of the rubber lining?
It can also be made from steel and PTFE! In this way, the lifespan will be very long
For saltwater corrosion protection, rubber-lined tanks or fiberglass-reinforced plastic tanks are used, with low calcium and magnesium levels
Reply to 1# Green Uniform Dream: Both rubber lining and glass flake coating can be used for saltwater storage tanks, but rubber lining is more expensive. The temperature and alkalinity levels in saltwater should not be too high. Glass flakes are cheaper, easier to apply, and suitable for alkaline solutions. Both anti-corrosion measures require sandblasting for rust removal. Most manufacturers use glass flake. Additionally, I would like to recommend a corrosion-resistant material – polyurea, which can withstand temperatures of around 140 degrees, but its price is relatively high.
Reply to 3# Boating on the lake: Agree; the perspective is good as well
The anti-corrosion lining for saltwater tanks requires natural rubber, and on-site construction necessitates steam vulcanization at the site. The refined brine tank requires on-site lining with low-calcium and low-magnesium rubber, with a typical construction thickness of 4 mm. Using glass flake anti-corrosion methods is convenient for on-site application and inexpensive. The performance is definitely not as good as that of rubber. Our company produces rubber and glass flake resin, and offers on-site installation services. Jiangsu Kaiyuan, Zhai 15952621881
The sandblasted surface is to meet the Sa2 1/2 standard; the thickness of the lining rubber sheet is KH-15, with a thickness tolerance of (+15%, -10%). Construction can proceed when the humidity is below 85% or when there is no condensation. Vulcanization is carried out under atmospheric pressure, following the vulcanization curve for KH-15. Rubber lining inspection: visual inspection, hardness inspection, thickness inspection. Open source/Zhai QQ302552097
Sandblasting for rust removal is necessary; generally, SA2.5 standard is required. What is the saltwater tank used for? For primary brine, glass scales are sufficient for use. For secondary brine, it’s better to line it with low-calcium, low-magnesium adhesive; but I wonder how you’ll carry out the vulcanization process if you do the lining on-site After applying the adhesive, an electric spark test needs to be conducted
