Highly Corrosion-Resistant Stainless Steel Wastewater Storage Tank
description
Stainless steel is an iron-based alloy containing more than 12% chromium and is resistant to corrosion by atmospheric and liquid media, it is widely used in the field of wastewater treatment system.
Advantages of Stainless Steel Bolted Tanks for wastewater storage
The advantage of stainless steel bolted tanks in wastewater treatment systems lies in their ability to strike a balance between corrosion resistance and extreme reliability.The biggest difference from other solutions is that stainless steel tanks achieve corrosion resistance through their inherent material properties, rather than relying on an additional tank lining.
• Hygienic & Body anti-corrosion
Self-healing passivation film: A dense chromium oxide passivation film naturally forms on the surface of stainless steel. Even if scratched, this film can "self-heal" in the presence of oxygen, continuously protecting the substrate.
Stable throughout the entire life cycle: There is no risk of coating aging or peeling, and the anti-corrosion performance does not decline over time, fundamentally eliminating substrate corrosion problems caused by coating damage.
• Excellent Corrosion Resistance
Tolerance to extreme pH levels: By selecting different grades (such as 316L stainless steel), it is possible to easily handle strong acid and strong alkaline wastewater with a pH value that is consistently below 2 or above 12.
Resistance to high chloride ion corrosion: For high chloride ion wastewater from industries such as seafood processing and dyeing, ordinary carbon steel or 304 stainless steel is prone to pitting corrosion, while 316L stainless steel can effectively resist stress corrosion cracking caused by chloride ions.
Unaffected by high temperatures and thermal shock: It can withstand water temperatures above 45℃ for extended periods, and because its metal substrate and protective layer are made of the same material (both are stainless steel), it is highly resistant to heat and thermal shock.
Resistant to abrasive solids: For wastewater containing large amounts of sand, gravel, and slag, stainless steel is hard and has strong wear resistance.
• Fast Installation & High Reliability
Factoryprefabricated panels enable quick bolted assembly on site, shortening construction period. The structured design delivers strong seismic and hydraulic performance, ensuring stable operation.
