Types Of Octg Pipes

Oil Country Tubular Goods (OCTG) is a steel pipe that finds its applications in the oil and gas industries

. These pipes can be used for drilling and other operations of oil wells. Available in casing, drilling and tubing forms, OCTG ensures smooth operations in the sectors of oil and gas.

OCTG that stands for Oil Country Tubular Goods is basically used in the oil and gas industries. These pipes are extensively used in the operation of oil wells. OCTG pipe can be divided into three main categories, named as, drill pipes, casing and tubing pipes, however, these pipes are also called as line pipe or other kind of pipes that are used to transport and produce oil as well as gas.

Drill pipe is a heavy seamless tube that is used for the rotation of drill and circulation of the drilling fluid. It has 30ft (9m) long joints that are fixed with tool joints. Casing pipe comes in different sizes and its diameter ranges from 30 to 3 . Generally, it is used in the oil and gas industries to line the hole. On the other hand, tubing pipe is used for the production of oil or gas from the well bore. It is 30ft long and has a diameter of 4 to 1 . The tubing joints have a thread connection on each end.

The connectors that are used to fix the joints of casing and tubing pipes come in varying sizes and features as per the usage. Further, these connections can also be used as individual items that are referred to as couplings. Casing and tubing pipes are used more in the oil and gas industries than drill pipe, which is less expensive than these two.

Drill pipe and casing pipes have similar chemical composition and in fact, the minimum requirements for external diameter and wall thickness as per the API (American Petroleum Institute) standards are also similar to each other. Moreover, the requirements for mechanical strength in casing and tubing pipes also match to drill pipe. However, the API strength of high-end drill pipe is greater than the casing and tubing pipes.

The exceptional features of OCTG pipes account for their extensive use in the field of oil and gas industries. These pipes have excellent mechanical properties at high temperature and also have high precision in terms of size and shape. Besides this, OCTG pipes are corrosion resistance that makes it popular for operations in industrial sectors. These have high collapse strength and high connection strength, which makes it easy to connect with each other.

Oil Country Tubular Goods have number of applications in the field of oil and gas industries. These pipes are used in the petroleum cracking, ship-building and even construction work that involves deep foundations. The casing pipe of OCTG can be used in the form of open cut casing, culverts casing, tunnel casing, road bore casing, tunnel casing, high temperature casing and premium thread connection casing. Further, these are also used to construct drawing oil equipment as well as for other structural purposes.

Although there are suppliers that offer OCTG pipe, API pipe, ERW pipe and CSA pipe, but it is imperative for the industries to rope in a supplier that is reputable in the construction, oil and gas industries. Reliable suppliers can provide you OCTG pipe in varying specifications as per the project requirements. They make sure that the OCTG pipes offered are of premium quality and factory end finish in LTC, STC, Premium and Buttress connections.
