EN 10216 part 1 specifies the technical delivery condition for two qualities TR1 and TR2 of seamless tubes of circular cross section with specified room temperature properties made of non-alloy quality steel.

Manufacture: tubes to EN 10216-1 shall be manufactured by hot formed or cold finished.
Heat Treatment: the tubes shall be supplied in normalized or normalising-formed delivery condition.
Inspection & Test: tensile test, NDT, surface inspection and dimension check.
Optional Test: impact test for TR2.

Length: 5800mm; 6000mm; 10000mm; 11800mm; and so on.
Max length: 18000mm
