Conventional and maximum sizes of stainless steel seamless elbows
The standard sizes of stainless steel seamless elbows usually cover DN15 (1/2 inch) to DN500 (20 inches), of which DN500 (outer diameter of about 508mm) is the largest common industrial seamless forming size.
Stainless steel seamless elbows of different calibers are also suitable for different occasions. For example, small calibers (such as DN15-DN50) are mostly used for precision instruments or food equipment, and large calibers (such as DN300-DN500) are suitable for chemical pipelines or energy delivery systems.
In addition, some manufacturers can also expand stainless steel seamless elbows to DN600 (24 inches) through cold processing mandrel forming technology, but special thick-walled pipes are required to avoid thinning of the wall thickness during the forming process.
