OCTG Pipe & Tubing 

Steel Alloys & Services (SAS) strives to offer high-quality steel products for a variety of industrial markets, such as oil line pipes for the oil & gas industry. 

Oil Country Tubular Goods, or OCTG for short, is the term used primarily to describe the piping materials used in the production of oil and gas (drilling activities). OCTG pipe is typically produced in accordance with API or associated standard specifications.

It may also be used as a collective term for several petroleum industry products utilized in both onshore and offshore environments, such as:

• Drill Pipe
• Steel Casing Pipe
• Tubing Pipe
• Couplings
• Connections
• Accessories.

OCTG pipes require dependable hardness to meet their standard requirements. Thus, regardless of the type of octg - tubing, pipe, or drill pipe - there is an established level of super hardness that must be achieved.

Dependable hardness is a standard requirement for all OCTG pipes. OCTG tubing, OCTG pipe, and OCTG drill pipe all have to meet a specific requirement that is constantly focused on extreme hardness. Manganese and chromium are the primary alloys utilized to check cohesion and durability in order to achieve the requirement. Thus, regardless of the type of OCTG - tubing, pipe, or drill pipe - there is an established level of super hardness that must be achieved.

The main issue with manganese and chromium, sulfide stress cracking, has been resolved with recent advancements. Chromium and manganese limits are addressed by combining molybdenum and alloy. As a result, there is no longer any need to worry about sulfide stress cracking because OCTG pipes are stronger than before.

We stock OCTG products for a variety of down hole tools in the following grades, connections, and conditions.

Outside Diameter Range: 1.315” (33.4 mm) to 20.000” (508 mm)

Manufacturing Process:

Seamless (SMLS): SMLS pipe process begins by heating a solid steel billet and then piercing it with a mandrel to shape it into a tube, it is then stretched or rolled into the desired diameter, length, and wall thickness.

Welded (ERW): ERW pipe is made by taking hot rolled steel coils and forming them into a cylinder followed by welding the edges together.

Connections: Plain end, API (STC/LTC/BTC), Premium Threaded/Coupled/Flush/Semi-Flush

Grades: H40, J55, N80, L80, T95, C95, P110, C110, Q125, 13cr80, 13cr85, S13cr-95, S13cr-110
