ASME SA135/SA135M
ASME SA135/SA135M is the standard specification for electric-resistance-welded steel pipe. It covers two grades of ERW steel pipe in NPS 2 to NPS 30 [DN 50 to DN 750], with nominal (average) wall thickness up to 0.500″ [12.7 mm], and in nominal sizes NPS 3/4 to NPS 5 [DN 20 to DN 125] with nominal (average) wall thickness 0.083″ [2.11 mm] to 0.134″ [3.40 mm], depending on size. Pipe having other dimensions may be furnished provided such pipe complies with all other requirements of this specification.
