Rubber hoses are indispensable in modern industry, and while most hoses on the market are designed to be corrosion-resistant, they can still succumb to corrosion over time. Why do even corrosion-resistant hoses corrode? Everflex is here to break down the key factors.
Factors Causing Corrosion in Corrosion-Resistant Rubber Hoses
1. Pickling Process Issues
Pickling is commonly used to remove the thin oxide layer formed on welds and heat-affected zones. However, controlling the pickling time and temperature is tricky. At high temperatures, prolonged pickling can excessively corrode the bellows, leaving the surface dark, dull, or even iron-gray. If the pickling temperature is too high, the surface may become rough and dark gray, with corrosion zones potentially forming in the weld’s heat-affected zone. All these issues can lead to corrosion and eventual perforation.
2. Poor Hose Material Quality
As demand for rubber hoses grows, so does the number of suppliers. Unfortunately, not all provide high-quality products. Many factories use recycled materials instead of premium raw materials, introducing impurities into the hose. These impurities significantly reduce the hose’s corrosion resistance and other vital properties.
3. Corrosive Media and Active Anions
When corrosive substances (like acids, alkalis) or active anions (such as chloride or sulfide ions) flow through the hose, they can attack weak points in the passivation film, particularly at the edge of the weld fusion line. This creates tiny corrosion pores, leading to pitting corrosion and leaks.
How to Prevent Hose Corrosion
The key to avoiding these issues starts with choosing a reliable supplier. Orientflex uses top-grade raw materials in all our rubber hoses, ensuring every product meets strict quality standards before delivery. Our corrosion-resistant hoses are built to withstand harsh environments, offering cost-effective solutions that prioritize durability and performance.
