        It is possible to manufacture pipes of sizes in the range of EN 10220 (DIN 2448).

        By agreement, the pipes are manufactured with the outer diameter as follows: 229, 254, 267, 298.5, 305, 330, 368, and 377 mm.  

        The pipes are delivered by length as follows:

        • technological length from 6.0 to 12.0 m (with the maximum length difference of 2000 mm per order item), less than 6 m by agreement;
        • the length of 10 % of delivered pipes may be less than the minimum value, but not shorter than 75 % of the minimum length;
        • fixed length from 6.0 to 12.0 m (with the deviations of ± 500 mm), less than 6 m by agreement;
        • precise length  from 6.0 to 12.0 m to a tolerance of + 15 mm within the range of technological one (should be stipulated at the time of entering into a purchase order)

        Mandatory Requirements:

        • carrying out the chemical composition control by the mechanical properties;
        • delivery of pipes with standardized carbon equivalent
