API 5CT L80-1(L809Cr,L8013Cr) OIL FIELD CASING PIPE

We have the ability to detect the whole process. We can fully guarantee the high quality of the products.The API 5CT L80 oilfield casing pipe be made of three Grades,including L80-1 ,L80 9 Cr ,L80 13Cr. these three Grades keep the consistent mechanical properties,but different heat treatment method and chemical composition.

It is well known that oil casing is the important lifeline for maintaining oil wells’ operation. But geographical environment is totally different in different areas and the connection of underground force is very complex. A variety of forces acting on the pipeline together, for example: tension, pressure, bending and twisting stress, all of which require oil casing should reach a higher level of quality. Oil casing’s damage for some reason will cause the oil wells’ production decline; some time seriously it will make well abandonment. So our company produces L80 steel grade oil casing strictly according to the API 5 CT standards.

Usage:

The API 5CT L80 oilfield casing pipe is an advanced type in the process of oil drilling.the mechanical performance is higher than the casing made of J55,N80. with relatively hight price,the product applies to more complicated geological conditions,and runs down deeper into the well. in the exploitation of oil and gas,the use of L80 is less frequent than J55,N80 and other Grades..

Q: How are steel pipes used in desalination plants?: Steel pipes are used in desalination plants to transport water, brine, and chemicals throughout the facility. They are highly durable and corrosion-resistant, making them ideal for handling the high-pressure and corrosive nature of the desalination process. Steel pipes ensure efficient and reliable water distribution, contributing to the overall effectiveness of desalination plants in converting seawater into fresh water.

Q: Are steel pipes suitable for semiconductor manufacturing plants?: Yes, steel pipes are suitable for semiconductor manufacturing plants. Steel pipes are known for their durability, strength, and resistance to corrosion, making them an excellent choice for various industrial applications, including semiconductor manufacturing. In semiconductor manufacturing plants, various chemicals and gases are used throughout the production process. Steel pipes are highly resistant to corrosion and can withstand the harsh chemicals and gases commonly found in semiconductor manufacturing environments, ensuring the integrity and longevity of the piping system. Furthermore, steel pipes can handle high-pressure applications, which are often required in semiconductor manufacturing plants. They have excellent mechanical properties and can withstand heavy loads and stress, making them reliable for transporting fluids and gases at high pressures. Another advantage of steel pipes is their flexibility in terms of size and shape. Semiconductor manufacturing plants often require a complex and intricate piping system to accommodate different processes and equipment. Steel pipes can be easily customized and fabricated to fit specific requirements, allowing for efficient and seamless integration into the plant's infrastructure. Overall, steel pipes offer the necessary qualities and characteristics required for semiconductor manufacturing plants. Their durability, corrosion resistance, high-pressure capabilities, and flexibility make them a suitable choice for transporting chemicals and gases in this industry.

Q: How do you determine the pipe schedule for steel pipes?: The pipe schedule for steel pipes is determined based on various factors such as the pipe's nominal size, wall thickness, and the application requirements. The pipe schedule is a standardized system that indicates the thickness of the pipe's wall, which affects its pressure rating and suitability for different applications. Factors like the fluid type, temperature, and pressure it will be subjected to help determine the appropriate pipe schedule to ensure safe and efficient operation.

Q: How can two smooth steel pipes be joined? The size of the two pipe is different (except for welding): Rectangular fastener: used for the connection of two vertical intersecting steel tubes. It relies on the frictional force between the fastener and the steel tube to carry the load.Swivel fastener: used for connecting two steel tubes intersecting at any angle

Q: How are steel pipes used in the agriculture industry?: Steel pipes are used in the agriculture industry for various purposes such as irrigation systems, drainage systems, and livestock handling equipment. They provide a durable and reliable solution for transporting water, nutrients, and effluents, ensuring efficient and effective operations in farm settings.

Q: How are steel pipes measured and categorized?: Steel pipes are typically measured and categorized based on their outer diameter, wall thickness, and length. The outer diameter refers to the measurement of the pipe's cross-sectional width, while the wall thickness refers to the thickness of the pipe's walls. These measurements are usually expressed in millimeters or inches. Categorization of steel pipes is done based on their purpose and specifications. The most common categorization is based on the pipe's pressure rating, which determines its ability to withstand different levels of internal or external pressure. Pipes are classified into various pressure classes, such as Schedule 40, Schedule 80, and Schedule 160, among others. The higher the pressure class, the thicker and stronger the pipe. Another way to categorize steel pipes is based on their manufacturing process and material composition. For example, seamless steel pipes are produced through a process that involves piercing a solid bar of steel to form a hollow tube, while welded steel pipes are made by rolling and welding a flat steel sheet or strip into a cylindrical shape. Additionally, steel pipes can be categorized based on their material composition, such as carbon steel pipes, stainless steel pipes, or alloy steel pipes. Steel pipes are also categorized based on their end connections or fittings. Common types of pipe ends include threaded ends, which are suitable for screwing fittings onto the pipe, and plain ends, which are typically used for welding or flanging connections. Overall, the measurement and categorization of steel pipes play a crucial role in ensuring their proper selection and usage in various industries, such as construction, oil and gas, plumbing, and manufacturing.

Q: How to make the steel pipe spray paint is not easy to fall off?: First, clean the surface of the object to be sprayed (pay attention to whether or not to paint off, which is the key):Remove rust stains, oil and so on, when spraying, the nozzle and spray the best distance is 20cm, should be two times forming, first thin spray again, dry, and then spray second times, this is more uniform, and not easy to hang

Q: How do you calculate the weight of steel pipes?: To calculate the weight of steel pipes, you can use the formula: weight = volume × density. The volume of a steel pipe can be calculated by multiplying its cross-sectional area (πr²) with its length. The density of steel is typically known, or you can refer to a density table. By plugging in these values, you can determine the weight of steel pipes.

Q: Are steel pipes resistant to fire?: Yes, steel pipes are highly resistant to fire due to their high melting point and ability to withstand intense heat and flames.

Q: What are the different methods of lining steel pipes?: There are several methods of lining steel pipes, including cement lining, epoxy lining, polyethylene lining, and bituminous lining. These methods are used to protect the inside surface of the steel pipes from corrosion, erosion, and other forms of damage, ensuring their longevity and optimal performance.
