        *- it may be manufactured by agreement

        The pipes of sizes, non-specified in the Table as well as with the changes in mechanical properties may be manufactured under the Supplement Agreement.

        The pipes being delivered by length are as follows:

        • random length from 6 to 12.0 m;
        • specified length within the range of random length;
        • multiple specified length within the range of random length with an allowance of 5 mm for each cut

        At the Customer’s request, it is possible to carry out the following:

        • hydraulic pressure or nondestructive testing;
        • one or some tests as follows: bend, drift expanding, flanging, and flattening tests, 
        • impact bending test;
        • chamfering (to be agreed by the wall thickness);
        • heat treatment;
        • control of macrostructure (for pipes with the wall thickness of 12 mm and over)

        * The wall thickness of 14 mm for pipes with the diameter of 114 mm made of steels 10 and 20 is assured under the Supplement Agreement

        There may be manufactured the pipes of sizes, non-specified in the Table.

        The pipes delivered by length are as follows:

        • - random length from 1.5 to 11.5 m;
        • -  specified length from 4.5 to 9 m;
        • -  multiple specified length from 1.5 to 9

        Mandatory Requirements:

        • carrying out the hydraulic pressure or nondestructive testing;
        • carrying out the bend test;
        • carrying out the flattening test (for pipes with the wall thickness non-exceeding 15 % of the outer diameter)

        At the Customer’s request, it is possible to carry out the following:

        • carrying out the nondestructive testing;
        • carrying out the impact bending test (for pipes with the wall thickness of 5 mm and over);
