OCTG

Seamles OCTG Materials

Nippon Steel's OCTG Materials cover the largest range of applications from Carbon steel to Nickel based alloys. Whether you are looking for corrosion resistance to CO2 or H2S, high strength, high collapse, heavy wall, special drift and so on, SM series will safely tackle with your most severe drilling environments. 

Seamless OCTG Connections

VAM® product line provides You with the most reliable way to connect OCTG tubulars. VAM® Premium connections are not only field proven, but qualified against the most stringent testing procedures and benefit from the largest worldwide support.

Large OD ERW Casing Material

Welded) OCTG material. This material provides superior impact toughness properties with YS (Yield
Strength) ranging from 95 to 110 ksi and with a guaranteed min. wall thickness 92.5% of specified nominal
WT. The high dimensional control & accuracy of wall
thickness and outside diameter provide better
drift
ability, internal yield pressure (burst) and collapse resistance.
This material is a cost effective alternative to API 5CT / ISO 11960 R95 seamless material.
OD & Weights:
as per API 5CT/ISO 11960, pleas e refer to Table 1. Material can be delivered in plain end
conditions, API Connections or NSMAX
TM GR Connections.
Special application:
Please contact NIPPON STEEL engineers, should you require any specific size,
weight, drift or any other information.

NT-95DE is a NIPPON STEEL proprietary Carbon Steel HF ERW (High Frequency Electric Resistance Welded) OCTG material. NT-95DE provides superior impact toughness properties with YS (Yield Strength) ranging from 95 to 110 ksi and with a guaranteed min. wall thickness 92.5% of specified nominal WT. The high dimensional control & accuracy of wall thickness and outside diameter provide better drift-ability, internal yield pressure (burst) and collapse resistance. NT-95DE is a cost effective alternative to API 5CT / ISO 11960 R95 seamless material.

Large OD ERW Casing Connections

Nippon Steel has developped prorietary connection for Large OD ERW Casing named NSMAXTM-GR.                      NSMAXTM-GR is available on 18", 18-5/8" and 20" OD. This new connection provides Fast & Stable Running (lower risk of cross-threading and galling) and Reliable Seal Performance (100% VME Liquid + 2,000 psi Gas) trough improved thread design.                                                                    NSMAXTM-GR has been already adopted by Norwegian customer and run successfully at the North Sea's offshore project.

Line Pipe

Nippon Steel masters both seamless and welded line pipe technologies with high purity steel, high quality pipes to fulfill the requirements of all applications and hostile environments whether onshore, offshore, corrosive, large diameters, high strength, heavy wall and so on.

Specialty Tubes

From carbon steel to high corrosion resistant alloys, Nippon Steel's Specialty Tubes does precisely fit your purposes : thermal and nuclear power plants, oil refineries and petrochemical, chemical and automotive industries.
