What is the Material of N80 in N80 Casing Pipe?
Generally speaking, when you're talking about the material of an N80 casing pipe and 20" API 5L X60 Pipeline, it's usually steel. The material of N80 can be very different depending on what kind of process is used for its manufacture. Some are heat treated, while others are oil quenched. The tensile properties of the steel can vary depending on how the steel is heated. So before you buy a casing pipe, it's important to know what kind of metal is used in the pipe.

Application
Among all the sleeve pipes in the world, the petroleum casing pipe is a tad over 50% of the total pie. The sleeve octocentic is a long threaded pipe with an integral seam that is heat treated. The best part is it's not hard to find a good supplier. The most common grade of petroleum casing is ASTM A106. The material is a high-strength low-alloy steel, which is known for its excellent resistance to oxidation and other decomposition processes.
The most important function of the oil casing pipe is to provide fluid transport for oil and gas wells. The material is also used for supporting the sidewall of an oil well during drilling. The petroleum casing is often supplied by welded tube manufacturing. The tube's quality is quite impressive for its price point. The pipe has a small diameter and is capable of transporting a variety of fluids, ranging from water to oil.

Tensile properties
Several different forces influence the tensile properties of casing pipe. They include flexing and torsional tension. These forces are important in the oil and gas industry, where casing pipes are used like LSAW Steel pipes.
The American Petroleum Institute sets specifications for tubing used in oil and gas wells. They are graded according to tensile strength and hardness. Depending on the temperature of the service environment, casing properties change.
Grade N80 is the oldest of the API tubing grades. It is available in various sizes. It is suitable for wells that have sweet oil and gas. It has a tensile strength of 689MPa.
The N80 casing pipe is used for natural gas and coal bed methane extraction. It has a higher mechanical property than the J55. However, it is less expensive. It is also less expensive than the K55. It is used in shallow wells.
N80 is divided into two types, N80-1 and N80-Q. These two are characterized by their chemical composition and heat treatment. Compared with the other grades, N80-1 is cheaper to produce. The heat treatment process for N80-Q involves quenching and tempering. This results in a higher internal pressure and higher
collapsing strenared with API 5CT J55 and K55, N80 casing pipe has better mechanical properties. It is widely used in coal bed methane extraction, natural gas extraction, geothermal wells, and middle level oil extraction. Besides, it is able to perform complex dvelopment in deeper holes.
The basic characteristics of N80 casing pipe are tensile strength, yield strength, tensile strength at a low temperature, tensile strength at a high temperature, and elongation. It is widely used in geothermal wells, sweet oil and gas wells, middle level oil extraction, and coal bed methane extraction.
The mechanical properties of N80 casing pipe can be improved through heat treatment. However, it is important to select the appropriate heat treatment process. If the heat treatment process is improper, it may lead to defects and affect the strength of the product.
During the heat treatment process, the temperature should be adjusted according to the situation of the stove coal gas. After the final heat treatment, the steel grade M65 and L80 should not be cold worked.
Oil quenching process
During the process of production, temperature control is the most important link like 316 stainless steel tubing. The quality of finished product depends on the results of the heat treatment process. It is important to prevent high-temperature brittleness of the oil casing pipe. The most effective way to achieve the purpose is to carry out low-temperature quenching.
The heat treatment process can make the oil casing more resistant to corrosion and destroy. In addition, it can also improve the mechanical properties. The oil casing can be divided into several types, including L80, N80, K55 and H40. Each grade has a unique color. These grades are used in various wells.
Generally, the mechanical properties of N80 casing are higher than those of K55 and J55. The N80 casing pipe can be used in more difficult formations. It is widely used in coal bed methane extraction and natural gas extraction. It is produced in compliance with the API requirements.
