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..

OCGT PIPE

Q: Can steel pipes be used for wastewater systems?: Yes, steel pipes can be used for wastewater systems. Steel pipes are known for their durability, strength, and resistance to corrosion, which makes them a suitable choice for transporting wastewater.

Q: How are steel pipes coated for insulation purposes?: Steel pipes are commonly coated for insulation purposes through a process called external coating. This involves applying a layer of insulating material, such as polyethylene or epoxy, onto the surface of the steel pipe. The coating is carefully applied to ensure a uniform and continuous layer, which helps to prevent heat transfer and protect the pipe from corrosion.

Q: What are the different coating materials used for steel pipes?: There are several different coating materials used for steel pipes, including epoxy, polyethylene, polyurethane, and zinc. These coatings are applied to the exterior of the pipes to provide protection against corrosion, abrasion, and other environmental factors. Each coating material has its own specific characteristics and is chosen based on the intended application and the level of protection required.

Q: What is the difference between hot dip galvanized steel pipe and galvanized steel pipe?: The difference between the process is that the hot dip galvanized pipe is dipped in the molten zinc bath and the galvanized pipe is plated with a metallic surface by means of unidirectional current in the plating bath. Hot plating process is fast, the coating is thick and consumes more zinc. Ordinary galvanized slow speed, thin coating.

Q: Are steel pipes suitable for underground drainage systems?: Indeed, steel pipes prove to be a fitting choice for underground drainage systems. The multitude of qualities possessed by steel pipes contributes to their popularity in this field. Firstly, their robustness and endurance enable them to withstand high levels of pressure and heavy loads. Moreover, steel pipes are resistant to corrosion, which prolongs their lifespan and reduces the need for frequent maintenance or replacement. Furthermore, steel pipes possess the advantage of adaptability and versatility in various soil conditions. They can be easily customized to match the specific requirements of the drainage system, encompassing different diameters and lengths. Additionally, steel pipes can be welded together, ensuring a secure and tight connection that effectively prevents leakage and the infiltration of groundwater. Another benefit of utilizing steel pipes in underground drainage systems lies in their capability to handle a wide range of temperatures. Their resistance to extreme heat or cold renders them suitable for diverse climates and environments. Nevertheless, it is important to acknowledge that steel pipes can be more costly compared to alternative materials such as PVC or HDPE pipes. Additionally, their weight and installation process may pose challenges, necessitating specialized equipment and expertise. In conclusion, steel pipes provide a dependable and long-lasting solution for underground drainage systems, particularly in regions where durability and strength are vital considerations.

Q: How do steel pipes handle seismic expansion joints?: Steel pipes handle seismic expansion joints by incorporating flexible components, such as bellows or expansion joints, which can absorb the movement caused by seismic activity. These flexible components allow the pipes to expand and contract without causing stress or damage to the system, ensuring the integrity and longevity of the pipeline during seismic events.

Q: How are steel pipes classified based on pressure ratings?: Steel pipes are classified based on pressure ratings into different categories such as schedule numbers or pressure classes, which indicate their ability to withstand different levels of pressure.

Q: What are the main aspects of precision steel tubes?: Its inside and outside diameter size can be accurate to less than 0.2mm, and it is widely used in the manufacture of precision machinery parts and engineering structure when the bending resistance and torsion strength are the same. It is also used to produce all kinds of conventional weapons, guns, shells, bearings and so on.

Q: How are steel pipes used in the manufacturing of food processing equipment?: Steel pipes are commonly used in the manufacturing of food processing equipment due to their durability, strength, and resistance to corrosion. These pipes are used to transport various food products such as liquids, powders, and gases within the equipment. They are also utilized in the construction of frames, supports, and structures for food processing machinery, ensuring stability and longevity. Additionally, steel pipes are often employed in the creation of heat exchangers, which are crucial for heating or cooling purposes in food processing equipment.

Q: Are steel pipes resistant to UV degradation?: In general, steel pipes lack resistance to UV degradation. When exposed to ultraviolet (UV) radiation for extended periods, steel pipes may experience different types of degradation. The steel can become prone to brittleness, resulting in cracks and potential failure. Moreover, UV radiation can induce corrosion and discoloration on the surface of the steel pipes. To counteract the effects of UV degradation, it is possible to apply protective coatings or paint to create a barrier against UV radiation. Regular maintenance and inspections are crucial to detect any indications of UV degradation and implement necessary actions to prevent further deterioration.
