EN 10217-2 is a European standard for welded steel tubes for pressure purposes. The standard specifies the technical delivery conditions for electric welded tubes made of non-alloy and alloy steel with specified elevated temperature properties.

The tubes covered by EN 10217-2 are intended for use in pressure systems at room temperature or at elevated temperatures. They can be used for conveying fluids, gases, and steam, as well as for structural purposes.

The standard covers tubes with diameters ranging from 17.2 mm to 1,420 mm and with wall thicknesses up to 40 mm. The tubes can be supplied in either circular, square, or rectangular shapes.

EN 10217-2 distinguishes between two classes of tubes: Class A and Class B. Class A tubes have a welded seam that is 100% radiographically tested, while Class B tubes have a welded seam that is either 100% radiographically tested or subjected to an ultrasonic test in accordance with the standard.

The standard also specifies the types of steel that can be used for the manufacture of the tubes, as well as the heat treatment processes that can be applied. The types of steel include P235TR1, P235TR2, P265TR1, P265TR2, and P355N. The heat treatment processes include normalized, normalized and tempered, and quenched and tempered.

EN 10217-2 also specifies the tolerances on dimensions and shape, as well as the inspection and testing procedures that must be carried out on the tubes before they can be delivered. The inspection and testing procedures include visual inspection, dimensional inspection, flattening test, tensile test, impact test, and non-destructive testing such as ultrasonic testing and radiographic testing.

In summary, EN 10217-2 specifies the technical delivery conditions for electric welded tubes made of non-alloy and alloy steel for use in pressure systems at room temperature or at elevated temperatures. The standard covers tubes with a wide range of dimensions and shapes, and specifies the types of steel that can be used, as well as the heat treatment processes and inspection and testing procedures that must be carried out.
