Corrosion causes and protective measures of HDPE stainless steel pipeline
This paper analyzed the causes of corrosion in stainless steel pipeline of HDPE plant,checked the liquid at the corrosion site and finally determined it was Cl-corrosion which also caused the problems such as leakage of heating steam pipe of dryer and leakage of water cooler due to the technological characteristics.Therefore,preventive measures to prevent Cl-corrosion were proposed,such as,the use of more corrosion-resistant metal materials in the design,enhancement of leakage management,the use of inorganic anti-corrosion coatings,etc.,which got the good effect on application,to ensure the stable production of HDPE plant.
