Production Size Range
Outside diameter: 21.3 mm – 323.9 mm · Wall thickness: 2 mm – 10 (13) mm · Length: 1/2"–3" = 5–8 m (1/2"–1 1/2" = 4–8.5 m); 6"–10" = 5–13 m (2"–6" = 5–14 m; 6"–12" = 5–14.6 m).
Production and Test Properties
Natural gas pipes are produced to API 5L. Natural gas installation pipes are manufactured with beveled ends. The pipes are varnish-coated. Ultrasonic and Eddy Current non-destructive tests are applied; they are tested twice. All pipes undergo a 100% hydrostatic pressure test and a magnetic test to check their leak-tightness and any defect in their metallographic structure.
