1. Definition of
DN80 Galvanized Steel Pipe
DN80 galvanized steel pipe refers to a galvanized steel pipe with an outer diameter of 80 mm and a wall thickness of 3.5 mm. It is a medium-sized steel pipe primarily used for transportation and structural applications in industries such as liquids, gases, petroleum, chemicals, shipbuilding, and machinery.
2. Standards for DN80 Galvanized Steel Pipe
DN80 galvanized steel pipe has both domestic and international standards. The main domestic standards are GB/T 3091-2015 "Welded Steel Pipe" and GB/T 13793-2016 "Long Straight Welded Seam Steel Pipe." International standards include ASTM A53, BS1387, EN10255, and DIN2440. These standards specify the material, chemical composition, mechanical properties, dimensions, weight, and markings of DN80 galvanized steel pipe, ensuring the quality and performance of the pipe.
3. DN80 Galvanized Steel Pipe Size Range
The size range of DN80 galvanized steel pipe is determined according to national and international standards. According to the domestic standards GB/T 3091-2015 "Welded Steel Pipe" and GB/T 13793-2016 "Long Straight Welded Seam Steel Pipe," the size range of DN80 galvanized steel pipe is as follows: outer diameter: 76.1-81.0 mm, wall thickness: 3.0-3.5 mm, length: generally 6 meters, but custom lengths are also available.
4. Advantages and Disadvantages of DN80 Galvanized Steel Pipe
The advantages of DN80 galvanized steel pipe include excellent corrosion resistance, long service life, low cost, and easy installation. However, its disadvantages are its heavy weight and susceptibility to rust. However, galvanizing significantly improves its corrosion resistance, effectively preventing rust and corrosion, and ensuring a long service life.
5. Applications of DN80 Galvanized Steel Pipe
DN80 galvanized steel pipe is widely used in industries such as construction, transportation, petroleum, chemical engineering, metallurgy, machinery, and aerospace. It is primarily used to transport media such as water, gas, oil, and steam. It can also be used in the construction of bridges, building structures, and mechanical parts.
In short, DN80 galvanized steel pipe is a commonly used type of steel pipe with excellent corrosion resistance and a long service life. It is one of the preferred materials for transportation and structural applications in various industries.
