The specification of steel pipes is represented by the nominal diameter (mm), which is an approximate value of the inner diameter. Traditionally, inches are commonly used, such as 11/2. Welded steel pipes for low-pressure fluid transportation are not only directly used for fluid transportation, but also widely used as raw pipes for galvanized welded steel pipes for low-pressure fluid transportation.
