When transporting corrosive liquids, choosing the right material is critical to ensure the safety, stability and long-term operation of the system. The following are some materials suitable for transporting corrosive liquids and their characteristics:

Pipe material
Fiberglass pipe:
Features: It has excellent corrosion resistance and can resist the erosion of corrosive liquids such as strong acid and alkali.
Application scenario: Suitable for conveying all kinds of corrosive fluids, especially in chemical, pharmaceutical and other fields.
Note: The price is relatively high, but considering its long-term corrosion resistance and maintenance costs, the overall cost performance is still high.
Polyethylene pipe:
Features: With excellent corrosion resistance and fluidity, can transport all kinds of acid, alkali, salt and other corrosive liquids.
Application scenario: Widely used in chemical industry, environmental protection, water supply and drainage.
Note: Although the price is relatively low, additional protection may be required in some extremely corrosive environments.
Fluoroplastic pipe:
Features: Has very high corrosion resistance, can resist almost all strong acids, alkali and organic solvent corrosion.
Application scenario: It is suitable for transporting highly corrosive and high-purity liquids, such as chemical transportation in the semiconductor industry.
Note: High price, but excellent performance, suitable for extremely high material requirements.
Stainless steel pipe:
Features: With good corrosion resistance and mechanical strength, suitable for a variety of corrosive liquids.
Application scenario: Widely used in food, pharmaceutical, chemical and other fields.
Note: The corrosion resistance of stainless steel in different media is different, and the appropriate grade should be selected according to the specific medium.
Other materials
High silicon cast iron pump:
Features: The material is very hard, suitable for conveying sulfuric acid, hydrochloric acid and other media. But processing and cutting is difficult, brittle and fragile.
Application scenario: Used in specific corrosive liquid transportation occasions.
Lining pump:
Features: The substrate metal surface of the pump in contact with the liquid is lined with corrosion-resistant materials (such as natural synthetic rubber, stainless steel, titanium, plastic, etc.).
Application scenario: Suitable for the transportation of a variety of corrosive liquids, suitable lining materials can be selected according to the specific medium.
Stainless steel metal hose:
Features: Made of stainless steel corrugated pipe with one or more layers of steel wire or steel belt mesh sleeve, with excellent corrosion resistance, high temperature resistance, low temperature resistance.
Application scenario: It is one of the preferred hoses for conveying highly corrosive materials.
Polytetrafluoroethylene (PTFE) hose
Features: With very high corrosion resistance, can resist almost all strong acids, alkali and organic solvent corrosion.
Application scenario: Widely used in the conveying of highly corrosive materials.
