OCTG is the abbreviation for Oil Country Tubular Goods which refers to piping products which are used for oil and gas production, including drilling activities. The octg pipe can be manufactured based on API or other related standard specification. The tubing octg solutions are known for their hardness. It has chromium and manganese as their main alloys which confirms durability and cohesion. Molybdenum is added to the api octg products these days for eliminating sulphide stress cracking. These pipes can be used as drill pipes, casing, and tubing.

They are available in different grades and have different chemical compositions. It should undergo subsequent heat treatment. They are used in a wide range onshore and offshore applications. They have extremely high torque and high internal pressure. They are used in various heavy duty OCTG pipes. They are available in various dimensions and shapes, which can be customized according to the requirements of the client.
