Product Description
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.
