The American Petroleum Institute API standard specifically targets oil and gascasing, tubing and line pipe standards used in industry. In the standard, the casing and tubing steel grades are divided into several grades, namely H 40, J 55, K 55, N 80, L 80, C 90, T 95, P 110, Q 125, each level has a different heat process.
Oil Casing Function： Petroleum casing is a large diameter pipe that plays a role in fixing the walls or boreholes of oil and gas oil wells. Casing is lifeline to maintain oil well operation. Due to the different geological conditions and the complex state of the downhole force, the combined effects of tensile, compressive, bending, and torsional stresses act on the pipe body, which places
Casing Pipe. The shape of the casing section is round, in large diameter pipes and is inserted into the oil well, fixed with cement to protect other equipment that is mostly made of iron and steel. The oil well must be designed to withstand the force different from the external power, such as crushing, explosion, stress and chemical corruption.
P110 oil well casing is used to transport clean and clear water from the boreholes. This casing pipe is made of P110 steel. It is often used to reinforce the wall of oil well.
OCTG Casing and Tubing Pipe U. S. Steel Tubular Products has an annual capacity of 1.9 million net tons for tubular products, much of which is used by the oil and gas industries. Our facilities can provide a wide range of high quality, high strength, high toughness, seamless and high frequency electric weld (ERW) pipe.
After the casing is down, the cement is to be cemented. It is different from the oil pipe and the drill pipe and cannot be reused. It is a disposable material. Therefore, the consumption of casing accounts for more than 70% of all oil well pipes. Casing can be divided intoconduit, surface casing, technical casing and oil casing.

Casing pipe is a steel pipe commonly used in underground construction to protect utility lines of various types from getting damaged. 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. It is widely used in petroleum industry.

The corrosion problem of downhole oil casing pipe in China's offshore oil and gas fields is extremely serious, which seriously affects the service life of downhole oil casing and normal production of oil and gas fields. Through cement sealing, corrosion resistant alloy pipes, injection of corrosion inhibitors, use of anti corrosion coating pipes, and enhanced monitoring, the oil casing can be

Outside diameter of our oil casing and tubing is from 114.3mm to 339.72mm, our steel pipes have been tested with water pressure.
Oil casing pipe is large diameter pipes, so as to promote the drilling, have fixed the role of oil and gas oil casing or hole.Casing is inserted into the hole and fixed with cement, in order to prevent the borehole and separated strata borehole collapse, and ensure the drilling mud circulating flow.
The conventional production of TP110T steel grade oil pipe sets is 29CrMo44 and 26CrMo4. Relative toThe latter two, 27MnCrV contains less Mo element, which can greatly reduce production costs. However, after the production of 27MnCrV by normal austenitizing quenching process, there is obvious high temperature temper brittleness, resulting in low impact toughness and instability.
Seamless pipes are extensively applied for the nuclear device, gas, petrochemical, ship building and boiler industries. Bestar is a dedicated provider and exporter for high performance price ratio welded and seamless steel pipes covering various steel grades,such as tubing and casing, drill pipe, OCTG pipe,ERW pipe, LSAW pipe, SSAW pipe.
Casing Coupling Casing coupling is a short pipe used for connecting two casing pipes which have threads. This pipe coupling has internal threads (box thread) machined to match the external threads (pin thread) of the long joints of casing. The two joints of casing pipes are screwed into opposite ends of the casing coupling.

Well casing is Steel tubing that is threaded. Pin on bottom and box on top. TerminologyOCTG – oil country tubular goods, API – American petroleum institute The pipe is either steel plate that is welded or seamless tube that is formed. The well is drilled to a depth that is considered ‘as deep as possible’.
