In which applications within petrochemical production are cast iron pipes, water-gas pipes, and seamless steel pipes used? 【Video】@ChemicalKnowledgeE017

In petrochemical production, different pipe materials are suitable for specific applications due to their varying properties: 1. **Cast iron pipes**: They have strong corrosion resistance but lower toughness; they are often used for buried pipelines or to transport corrosive substances such as acidic or alkaline fluids. They are suitable for low-pressure, non-shockful environments such as sewage disposal or underground piping systems. 2. **Water-gas pipes (galvanized welded pipes)**: They have low costs and are easy to process, and are commonly used for transporting low-pressure water, air, or gas, such as in factory water systems and HVAC systems. However, due to the limitations of the galvanized coating, they are not suitable for use in high-temperature or highly corrosive environments. 3. **Seamless steel pipes**: Free of welds and possessing high strength, they are the preferred choice for high-pressure and high-temperature applications such as oil and gas main lines, reactor pipelines, and steam systems. They can withstand severe pressure fluctuations and extreme temperatures, ensuring safe operation.
