Seamless Pipes

Seamless pipes and tubing in carbon, alloy, stainless, duplex, nickel-alloys, non-ferrous grades according to the API 5L, ASME B36.10/B36.19, and EN dimensional specifications.

We supply the following seamless pipes grades and specifications ex-stock or ex-mill:

Seamless carbon steel pipes (API 5L/ASME B36.10/EN10220)

  • API 5L carbon steel pipes grade B (L245)/X42 (L290)/X52 (L360)/X60 (L405)/X65 (L450) PSL1/PSL2 plain and threaded ends
  • ASTM A106 carbon steel pipes grade B/C for high-temperature service
  • ASTM A53 carbon steel pipes grade B for fluids and general application (type “S”)
  • ASTM A333 carbon steel pipes grade 3/6 for low-temperature service
  • API 5CT OCTG casing and tubing pipes grade API H40, J55, K55, L80, N80, P110, and Q125
  • Clad pipes (CRA): carbon steel pipes with the application of other layering materials in the inside wall (example stainless steel or nickel alloys)
  • EN 10208-½ carbon steel line pipes grade L235
  • EN 10216-1 carbon steel pipes for general application grade P235
  • EN 10210 carbon steel pipes for structural applications grade S355 J0H/S355 J2H
  • EN 10224 carbon steel pipes for water applications grade L235
  • EN 10255 carbon steel pipes for gas applications grade S195T
  • EN 10297 carbon steel pipes for mechanical applications grade E355/E470
  • UNI 7683 carbon steel pipes for cable conduits grade FE360

Seamless alloy steel pipes (ASME B36.10)

  • ASTM A335 alloy pipes  grade P5/P9/P11/P22/P91 for high temperature (power generation plants)

Seamless stainless, Duplex, Nickel-alloy pipes (ASME B36.19)

  • ASTM A312 stainless steel pipes  Gr. TP304/304L/316/316L/321/321H/347 for corrosive service
  • ASTM A790 Duplex and Super Duplex pipes (UNS S32205-UNS S32803)
  • Seamless nickel-alloy pipes ASTM B161 (Nickel 200/201, seamless), B165 (Monel, seamless), B167 (Inconel 600, seamless), B444 (Inconel 625, seamless), B407 (Incoloy 800, seamless), B423 (Inconel 825, seamless), B622 (Hastelloy C276, seamless), otherwise called superalloy pipes

Tubing for Boilers, Heat-Exchangers, Superheaters (ASME)

  • Seamless tubing for boilers, heat exchangers and superheaters (ASTM A179 carbon steel, A209 alloy steel, A213/A269 stainless steel, A789 duplex, nickel-alloy grades, titanium B338)
  • EN 10216-2 carbon steel pipes for boilers grade P235 GH/ P265 GH

Seamless pipes are available in single random length (“SRL”: 5-7 meters, generally for pipes under 4″) or double random length (“DRL”: 11-13 meters, pipes above 4″), with plain ends (PE), beveled ends (BE), threaded ends (TE), or threaded and coupled ends (T&C). We can provide externally coated pipes (3PL), or internal lining in various materials (example PTFE-Teflon).

Pipe dimension charts: ASME B36.10 for carbon/alloy pipes, ASME B36.19 for stainless/duplex/nickel alloy/non-ferrous pipes, EN 10220 for carbon/alloy European pipes (EN 1127 for stainless and nickel alloys).
