Pipeline material for 50% hydrogen peroxide storage tank
Thread Content
As the title suggests, I would like to ask the experts: what material is suitable for use in the pipelines of storage tanks containing 50% hydrogen peroxide?
Basically, 321 is used the most.
Industrial 50% hydrogen peroxide is an acidic solution that contains chloride ions; therefore, pipes made of iron-based metals cannot be used. All austenitic stainless steels are also susceptible to corrosion caused by chloride ions. If the pressure in the pipeline is low, plastic pipes are recommended; if the pressure exceeds 0.2 MPa, plastic-lined (or fluorinated) carbon steel pipes, or glass-lined pipes should be used.
Hydrogen peroxide has a strong oxidizing property; can it be used with plastic pipes?
The storage tanks, pipelines, fittings, diaphragm pumps, etc. here are all made of 316L
The locations in contact with hydrogen peroxide are all 321
321. Fluorinated lining storage tanks are also prone to safety issues
