Casing Pipe

Description: Casing pipe is a special tubular product for oil (gas or water) extraction. Casing pipe is particularly exposed to axial tension and internal pressure by the pumped oil or gas emulsion. Casing pipes comply with Specifications on Casing and Tubing (API Spec 5CT), Specifications on Processing, Measuring and Inspecting Casing, Tubing and Threads (API Spec 5B) and other related standards.

Saigao Steel casing pipe Saigao Steel casing pipe, also known as encasement pipe, is most commonly used in underground construction to protect utility lines of various types from getting damaged. Such damage might occur due to the elements of nature or human activity. Saigao Steel casing pipe is used in different types of horizontal underground boring, where the pipe is jacked into an augered hole in segments and then connected together by welding or by threaded and coupled ends, or other proprietary pipe connectors such as the interference-fit Permalok interlocking push-on joint. The Saigao Steel casing pipe can also be set up and welded into a "ribbon" and then directionally pulled through a previously drilled hole under highways, railroads, lakes and rivers Saigao Steel casing pipe protects one or many of various types of utilities such as water mains, gas pipes, electrical power cables, fiber optic cables, etc. The utility lines that are run through the Saigao Steel casing pipe are most commonly mounted and spaced within the Saigao Steel casing pipe by using "casing spacers" that are made of various materials, including stainless steel or carbon steel and the more economical plastic versions. The ends of a Saigao Steel casing pipe "run" are normally sealed with "casing end seals", which can be of the "pull-on" or "wrap-around" rubber varieties. Saigao Steel casing pipe is also used in the construction of deep foundations. Specification Saigao Steel casing pipe generally has no specific specifications, other than the need for the material to be extremely straight and round. In some areas A.S.T.M. specifications may be required by project engineers. The specification most commonly called for is A.S.T.M. 139 Grade B. This specification gives parameters for minimum yield and tensile strength of the steel pipe being used for casing, and tolerances of straightness and concentricity. Saigao Steel casing pipe is often specified as ASTM A-252 which is a structural grade material that does not require hydrostatic testing and the inspection requirements are not stringent and it usually costs less than other grades such as A-53, A-139 or API 5L. Used natural gas line pipe is also used as casing on many projects because it is often reclaimed in very good condition and can offer a significant cost savings when compared to new steel pipe. Used pipe is most likely to not have any testing data associated with it and is generally used when the only required specification is a given diameter and wall thickness of Saigao Steel casing pipe.

Casing is a large-diameter pipe that serves as the structural retainer for the walls of oil and gas wells, or wellbore. It is inserted into a well bore and cemented in place to protect both subsurface formations and the wellbore from collapsing and to allow drilling fluid to circulate and extraction to take place. The following different types of casing are used in the extraction process: Surface casing - Protects the well from contamination in shallow water and gas layers. - Supports the wellhead equipment and sustains the weight of the other layers of casing. Intermediate casing - Isolates different layers of pressure to facilitate normal circulation of drilling fluid and protect the production casing. - Intermediate casing facilitates the installation of blow-out preventers, anti-leakage devices and tailpipes in the well. Production casing (oil string) - It is the conduit through which oil and gas pass from a below surface reservoir. - It protects the well and separates fluids into various layers. For the manufacture of casing, green pipes are threaded on each end at first. The threading is then inspected and, if necessary, rethreaded to ensure that the thread accurately connects to the coupling. The casing are strengthened by surface treatment and are subject to various inspections, including drifting and hydrostatic tests before they are coated and packaged into casing.
