1. Welded steel pipe: This is one of the most common types of iron cylinder pipes, made by welding. It can be used in a variety of applications, including water and natural gas transmission, as well as building structures.
2. Hot-dip galvanized steel pipe: This iron cylinder pipe is galvanized during the manufacturing process to improve its corrosion resistance. It is typically used in outdoor environments or in applications where protection from humidity and corrosion is required.
3. Black iron pipe: Also known as seamless steel pipe, this iron cylinder pipe is not galvanized. It is commonly used in low pressure water supply, gas and heating systems.
4. Stainless steel pipe: This iron cylinder pipe is made of stainless steel and has excellent corrosion resistance and strength. It is commonly used in chemical industry, food processing, medical equipment and other fields.
5. Cast iron pipe: This type of iron cylinder pipe is made of cast iron and has high strength and pressure resistance. It is commonly used in water supply systems, sewage treatment and drainage systems.
