Pipes are manufactured according to the requirements of the fol- lowing standards:
Pipes are manufactured in diameter range from 559 mm to 2032 mm, with plain or bevelled ends. Pipes in diameter from 559 mm to 914 mm are manufactured with one longitudinal weld and from diameter 1016 mm to 1620 mm with two welds, and above with three longitudinal welds.
Line pipes in diameter from 559 mm to 1219 mm are hydrosta- tically tested. The welds of pipes in diameters from 559 mm to 1422 mm are subject to non-destructive tests. Such tests are con- tinuously performed by X-ray.
Upon technical agreement, pipes may be delivered with different diameters and wall thicknesses that are specified in the table, in outside diameters from 559 mm to 2032 mm, in production lengths from 5,2 m to 8,2 m.
