Corrosion protection and lining of DN32 pipes
Thread Content
Can DN32 stainless steel pipes be coated for corrosion protection or lined? Is the diameter too small? What diameter of pipes are suitable for anti-corrosion and lining?

It seems impossible to add a lining; just upgrade the material directly
It’s stainless steel anyway; doesn’t it have built-in corrosion resistance? 321SS stainless steel offers good corrosion resistance; I’m not sure which type the original poster is using?
You’re wrong on this point; corrosion prevention is only targeted corrosion prevention. There are also media that can cause stainless steel to fail under corrosion. For the anti-corrosion of such small-diameter linings, it is better to simply upgrade the materials. For the medium, use materials with stronger corrosion resistance, such as titanium or nickel.
Mm-hmm, yes! The original poster didn’t mention the medium; under normal circumstances, 321SS already has quite good corrosion resistance!
Identifying the source of corrosion is essential to address it effectively! On this topic, if the corrosion of DN32 pipes is caused by hydrogen, \"self-propagating\" treatment can be used; whereas to prevent corrosion in the liquid phase, polymer coating technology can be employed. Compared to upgraded materials, it is generally still cost-effective.
