Product classification
API petroleum casing galvanized wire steel pipe 3PE anti-corrosion steel pipe
API 5CT petroleum casing 660 × 18 API5CT petroleum casing can be divided into seamless steel pipes and welded steel pipes, and large-diameter petroleum casing is generally submerged arc welded straight seam steel pipes. Mainly used for transporting liquids and gases such as oil, natural gas, coal gas, water, etc. The main application countries of this product are mainly distributed in the Middle East, Europe and America. The api5ct petroleum casing can be divided into three specifications based on its length: R-1, R-2, and R-3. The main materials are J55 K55 N80 L80 P110, etc. In extreme high-temperature and high-pressure environments, pipelines made of petroleum casing materials have their own unique natural advantages. Api5ct petroleum casing requires relevant inspection and testing from raw materials to products before leaving the factory, including flattening test, tensile test, impact test, tensile test, etc.

Oil casing is the lifeline for maintaining the operation of oil wells. Due to different geological conditions, the stress state underground is complex, and the combined effects of tension, compression, bending, and torsion stress on the casing body pose high requirements for the quality of the casing itself. Once the casing itself is damaged for some reason, it may lead to a reduction in production or even scrapping of the entire well.
According to the strength of the steel itself, the casing can be divided into different steel grades, namely J55, K55, N80, L80, C90, T95, P110, Q125, V150, etc. The steel grade used varies depending on the well condition and depth. In corrosive environments, it is also required that the casing itself has corrosion resistance. In areas with complex geological conditions, it is also required that the casing has anti collapse performance.
Technical specifications for petroleum casing:
(1) According to SY/T6194-96 regulations, the length of domestically produced casing is not fixed, with a range of 8-13m. But sleeves no less than 6m can be provided, and their quantity should not exceed 20%.
(2) The inner and outer surfaces of the casing must not have folds, wrinkles, delamination, cracks, creases, or scars. These defects should be completely removed, and the removal depth should not exceed 12.5% of the nominal wall thickness.
(3) The outer surface of the coupling must not have defects such as folding, hairlines, delamination, cracks, creases, scars, etc.
(4) The surface of the casing and coupling threads should be smooth, without burrs, tears, or other defects that could interrupt the thread and affect the strength and tight connection.

A casing is a large-diameter pipe that serves to fix the walls or wellbore of oil and natural gas wells. The casing is inserted into the wellbore and fixed with cement to prevent the wellbore from separating rock layers and collapsing, and to ensure the circulation of drilling mud for easy drilling and extraction. Different types of casings used in oil extraction:
Surface oil casing:
-Protect drilling from contamination by shallow water and gas layers,
-Support wellhead equipment and maintain the weight of other layers of casing.
Technical petroleum casing:
-Separate the pressure at different levels to ensure smooth and normal drilling fluid flow and protect the production casing.
-In order to install anti burst devices, leak prevention devices, and tail pipes in the drilling.
Oil reservoir casing:
-Export oil and natural gas from underground reservoirs.
-Used to protect drilling and separate drilling mud into layers.
-When producing oil casing, the outer diameter is usually 114.3 millimeters to 508 millimeters
