Casing and Tubing

The American Petroleum Institute (API) and the International Organization for Standardization (ISO) have established two basic types of pipes used for exploration and production in the oil and gas industry: casing and tubing. Casing and Tubing also known as OCTG. Casing and tubing strings are the main parts of the well construction. All wells drilled for the purpose of oil or gas production (or injecting materials into underground formations) must be cased with material with sufficient strength and functionality. Well casing pipe is a pipe used in oil, gas, or water wells to protect the well walls and stabilize the wellbore.Casing pipe is used to line the drilled borehole that is being utilized for oil extraction. Similar to drill pipes, oil well casing pipe is also subjected to axial tension and therefore needs to be made from high-quality, strong steel. Casing (well pipe casing) is a large-diameter pipe fixed in the borehole using cement.Tubing is the pipe used after drilling is completed to transport crude oil and natural gas from the oil or gas reservoir to the surface.

Application of Casing and Tubing

Casing and tubing are essential oil drilling equipment with various functions such as sealing perforations, supporting wellbore walls, preventing formation collapse, and controlling well flow. Casing and tubing are widely used in petroleum exploration, extraction, and transportation. During the exploration phase, casing and tubing are used to obtain geological samples and assess the properties of underground oil reservoirs. In the extraction phase, casing supports the wellbore walls, prevents wellbore collapse, and controls well flow. In the transportation phase, tubing is used to transport oil and natural gas.

Manufacturing Process of Casing and Tubing

Our casing and tubing are not only manufactured strictly in accordance with API standards, but we also develop proprietary grades for special application environments such as sour, high collapse, chrome and CRA. With these proprietary grades, we are able to provide the best solution for each customer's specific well conditions. All of our products are produced in accordance with the most stringent quality standards. Our operations have been globally ISO 9001 certified, implement a unified quality policy, and adopt a rigorous quality management system. If you need customized oil casing, choose us OASIS and we will provide you with satisfactory service.
