1. 6 meters (m): This is a common length, including European standard (EN), Japanese standard (JIS), etc. The 6 meter length is typically suitable for a variety of applications such as construction, piping, structural engineering, etc.
2. 12 meters (m): The 12-meter length is usually used in some large-scale engineering projects, such as long-distance transmission pipelines, high-pressure pipelines, etc., which can reduce the number of connecting joints.
3. 20 feet (ft): 20 feet is a common standard length, approximately 6.1 meters, usually used in the manufacture and supply of rolled pipes.
4. 40 feet (ft): 40 feet is twice the length of 20 feet, which is approximately 12.2 meters. This length is commonly used for international shipping and export to allow for easy loading in containers or transport vehicles.
5. Other customized lengths: In addition to the common standard lengths mentioned above, rolled pipes can also be manufactured into customized lengths according to customer needs. These lengths can be made to suit specific project requirements to reduce waste and the number of connecting joints.
