Pipes : Annual Spend

  • Additional Requirements to Standard Specifications

  • ASTM A333 Grade 6 Seamless up to 14” NPS

    • Normalized; NACE MR 0175 / ISO 15156 Certification;

    • CE = 0.42% max; Carbon (C) content = 0.23% max; Sulphur (S) = 0.010% max;

    • Phosphorous (P) = 0.020% max; Limits to Niobium (Nb) & Vanadium (V)

    • Cr, Mo, Ni, Cu, Nb, V shall be determined in chemical analysis and reported

  • ASTM A333 Grade 6 Welded or ASTM A671 CC 60 Cl.22 16” NPS & Larger only

    • In addition to above requirements: EFW/SAW; 100% RT;

    • ASTM A516 Gr. 60 plate shall be vacuum treated normalized; CE(llW) = 0.43%;

    • S = 0.003% max; P = 0.008% max; Nb + V = 0.020% max; HIC testing required

  • API 5L X60 PSL 2 Seamless (incl. Annex H and K)

    • Product Chemistry: C = 0.140% max; P = 0.018% max; Nb = 0.040% max;

    • Ti = 0.025% max; V = 0.080% max; Nb+Ti+V = 0.120% max; CE(llW) = 0.380% max

    • Charpy impact testing to -40C; min avg energy value 47 Joules/ 35 Joules min individual

    • Hardness testing per every 25 joints; Max hardness 250 HV10

    • HIC testing per NACE TM0284 using solution A of one pipe from each heat and size

    • SSC Tests (one per heat) per Annex H and clause H.2h

  • API 5L X60 PSL 2 Welded (for API 6A 5000/ASME class 2500 larger diameters)

    • SAW/DSAW only; Same requirements as seamless with slight modifications: C = 0.10%;

    • Si = 0.35%; S = 0.002%; P = 0.012%; Al = 0.06%; V = 0.040%; Nb+Ti+V = 0.10%

    • Max hardness 220 HV10

  • ASTM A312 316/316L Seamless

    • Solution heat treated and pickled

    • Estimated Annual Spend is over $ 200 MM by the Industry
