There are various ways to manufacture DIN V pipe fittings, such as pushing, pressing, forging, casting, etc. These methods categorize the fittings based on the process used to create them.
According to the pressure level classification, DIN V pipe fittings have approximately seventeen types, which align with the American pipe standards. These types include: Sch5s, Sch10s, Sch10, Sch20, Sch30, Sch40s, STD, Sch40, Sch60, Sch80s, XS; Sch80, SCH100, Sch120, Sch140, Sch160, XXS. Among them, the most commonly used types are STD and XS. It is worth noting that this classification system provides a wide range of options to cater to various pressure requirements in different applications.
The pipe fittings for DIN V are differentiated based on the radius of curvature. They are classified into two types of elbows: long radius and short radius elbows. Long radius elbows are those in which the outside diameter of the pipe has a radius of curvature that is 1.5 times, or R=1.5D. On the other hand, short radius elbows have a radius of curvature that is equal to the outside diameter of the pipe, with R=1.0D. Here, D represents the diameter of the elbow, while R represents the radius of curvature.
