SEAMLESS  OCTG

OCTG includes threaded  drill pipe, casing and tubing that are used in drilling, equipping and  operating oil and gas wells. The Company is Russia’s leading supplier of  seamless pipe for the oil and gas industry and occupies a stable position in  international markets.


Oilfield tubulars (OCTG)


image001


The  broad product portfolio of Mannesmann Line Pipe GmbH also includes HFI-welded  plain-end oilfield tubes to API 5CT in the 4 ½" (114.3 mm) to  24" (610.0 mm) size range.

These  oilfield tubes – or OCTG products (Oil Country Tubular Goods) – can be either  casings or tubings. Their applications include classic oil and gas wells,  geothermal wells and water wells, i.e. underground caverns or aquifers.

Our manufacturing program comprises the following API 5CT standard grades
Cold finished

  • H40

  • J55

  • K55 (similar to J550 but with higher minimum tensile strength)

Heat treated (quenched and tempered)

  • N80 Q

  • L80 (compared to N80, this material is subject to more stringent requirements in terms of maximum yield strength and maximum hardness. According to NACE MR0175, grade L80 steel can also be used in wells with sour (H2S) environments.)

  • R95 (yield and tensile strength between N80/L80 and P110)

  • P110 (for general use in deep wells)

Besides the standard grades, we have developed and supplied other grade variants for these products in response to individual customer needs, such as:

  • Tubes for underground storage applications such as caverns, where the tubes are not threaded and coupled but welded together on the rig – usually supplied with beveled ends (with specified notch impact toughness at -20 °C and restricted carbon equivalent):

    • J55 weldable (CET as per SEW088)

    • N80 Q weldable (quench and temper heat treated, CET as per SEW088)

  • Normalized tubes: K55 FBN (FBN = full-body normalized. In addition to K55 requirements, this material meets Charpy V-notch impact energy requirements at 0 °C (32 °F) as per API 5CT SR16.)

  • High-collapse tubes – On request, depending on the size and grade concerned, we can also       check whether a given tube material and size can be produced with increased resistance to external pressure.

  • J55 UPG – J55 grade to API with an upgrade option. Similar to Green Tubes, these tubes can be upgraded to N80, L80, R95 or P110 by special heat treatment.

Our plant  in Hamm produces tubes in diameters of 12 ¾" (323.9) to 24" (610.0  mm) and has a heat treatment shop  for normalizing and quench & temper treatment of the tubes. In addition, a full-body ultrasonic testing facility has been installed downstream of the hydrostatic  pipe tester, so as to accommodate in-line non-destructive testing of the  heat-treated tubes as specified by the applicable standards.

Our  plant in Siegen covers the 4 ½" (114.3 mm) to 16" (406.4 mm) size  range. Any necessary heat treatment of these tubes is carried out at the Hamm  location.


Why  not take advantage of our expertise? Together with you and our partners, we  develop flexible and, if required, unconventional solutions that are perfectly  customized to your needs. With us, you can plan swiftly and reliably, for  response times at Mannesmann Line Pipe are deliberately kept short.
