OCTG

OCTG means Oil Country Tubular Goods, which refers to steel used in oil and gas extraction and production processes, including Drill pipe, Casing, Tubing, Couplings, Connections and Accessories, for the oil and gas industry on land and offshore. API 5CT is the most common and important standard to ensure the normal production and exploitation of oil and gas.

Casing & Tubing

Casing

Casing and Tubing are both used in the process of drilling for petroleum.

Casing is placed before drilling begins and completely surrounds the wellbore. Its purpose is to protect the soil layers and groundwater from contamination by drilling mud and/or frac fluids. Additionally, casing stabilizes the wellbore. Drilling and casing operations alternate – the drill string is removed at predetermined intervals and the wellbore is lined and cemented with casing.

Casing Range of Sizes: 5 1/2” to 20” Length: R2, R3

Ends Type: BTC (Buttress Thread Coupling), LTC (Long Buttress Thread Coupling), Premium connection

Tubing

Tubing is used to carry petroleum from the well’s depths to the surface. This is the third phase of the wellbore process. Oil and gas occasionally self-elevate to the surface; however, pumps are typically required to bring the fluids to the surface. Besides the 4 1/2-inch diameter, tubing is normally smaller in diameter than casing. Consequently, tubing must be affixed to external support structures, such as a rig or platform, in order to prevent collapse due to pressure differentials.

Standard:API 5CT Grade: J55, K55, N80-1, N80Q, C90, C95, P110, Q125

Tubing range of Sizes: 1.05”, 1.315”, 1.66”, 1.9”, 2 3/8”, 3 1/2” and 4 1/2” Length: R2, R3
