Representation of the length of carbon/alloy steel pipes
Specified in ISO 4200, EN10220 or DIN2448, the specified size of steel pipe refers to the length, outside diameter, inside diameter and wall thickness of the steel pipe . The range size of steel is an effective measure to save materials. Today we will discuss the length of steel pipe. Delivery length is also known as customer required length or contract length. Steel pipe manufacturers or suppliers can supply according to standard length. The legal units of measurement for the length of steel pipe are “m”, ” cm” and “mm”. Random length Indefinite length refers to the length of steel pipe in the standard range and does not require fixed length, also known as the usual length. The steel pipes delivered by indefinite scale shall be delivered within the specified length range. For example, the standard of structural pipes stipulates: the length of hot-rolled (extruded and expanded) steel pipes is 3000mm ~ 12000mm; Cold drawn (rolled) steel tubes with a length of 2000mm ~ 10500mm ...
