Stainless Steel 316 thread Flange

Industry Application Scenario Cases

Marine Engineering

In seawater cooling systems, the pitting resistance index PREN of Stainless Steel 316 thread Flanges is ≥28, which is 1.5 times that of 304!

Food and pharmaceuticals

Withstands daily high-temperature acid and alkali washing, and has excellent cleaning tolerance

Certified by FDA/EC1935, no metal ion precipitation in this environment, super strong protection

Chemical processing

Phosphoric acid reaction tank: After replacing the carbon steel flange, the maintenance cost dropped by 67%

Chlor-alkali plant: In 3 years of tracking, zero corrosion in 80℃/20% NaCl solution, achieving impossible completion
