L245NS seamless steel pipe is a high-strength, low-alloy steel pipe widely used in pipeline systems in the oil, natural gas, chemical, power, and other industries. Due to its excellent mechanical properties and corrosion resistance, the L245NS seamless steel pipe has become the preferred material in many engineering projects.


① Standard GB/T9711 PSL2 Steel pipes for oil and gas industry pipeline transportation systems.

② The product should meet the requirements of TSG D7002 pressure pipeline original form test rules.

③ Seamless steel pipes are delivered in the following states: normalized rolling, normalized forming, normalized or normalized, and tempered.

④L245NS seamless steel pipe mass fraction, based on smelting analysis and product analysis, maximum %: carbon C: 0.14, silicon Si: 0.40, manganese Mn: 1.35, phosphorus p: 0.020, sulfur S: 0.003, titanium Ti: 0.040

⑤L245NS pipeline seamless steel pipe: yield minimum 245MPa, maximum 450MPa, tensile strength: minimum 415MPa, maximum 655MPa, yield ratio maximum 0.93


First of all, the high strength of the L245NS seamless steel pipe is one of its most prominent features. Its tensile strength reaches more than 410MPa, and its yield strength is also more than 245MPa, which enables it to maintain good stability and safety under harsh environments such as high pressure and high temperature. At the same time, the low alloy composition of L245NS seamless steel pipe also makes it have good toughness and weldability, which facilitates processing and installation at the project site.


Secondly, the corrosion resistance of the L245NS seamless steel pipe is also one of the reasons why it is so popular. When transporting media such as oil and natural gas, steel pipes are often corroded by various chemical substances, and the corrosion resistance of L245NS seamless steel pipe can effectively resist these corrosions and ensure the long-term stable operation of the pipeline. In addition, the inner and outer walls of L245NS seamless steel pipe are precisely processed, smooth, and flawless, which reduces the friction and resistance of the medium in the pipeline and improves transportation efficiency.


In addition to the above characteristics, the L245NS seamless steel pipe also has good plasticity and machinability. It can be formed by bending, expanding, shrinking, and other processing processes to meet various complex engineering needs. At the same time, the welding performance of L245NS seamless steel pipe is also excellent, and it can be connected by a variety of welding methods to ensure the sealing and safety of the pipeline system.


In practical applications, L245NS seamless steel pipe is widely used in the transportation pipeline systems of oil, natural gas, chemical industry, electric power, and other industries. In terms of oil and gas transportation, the high strength and corrosion resistance of L245NS seamless steel pipe can effectively ensure the safety and stability of the pipeline, and improve the transportation efficiency and economic benefits. In the chemical industry, the corrosion resistance and machinability of L245NS seamless steel pipe make it an important part of many chemical equipment, providing a reliable guarantee for chemical production. In the power industry, L245NS seamless steel pipe is widely used in the manufacture and installation of equipment such as boilers and steam turbines, ensuring the normal operation and power generation efficiency of power equipment.


In short, as a high-strength, low-alloy steel pipe material, L245NS seamless steel pipe has broad application prospects in the oil, gas, chemical, power, and other industries. Its excellent mechanical properties and corrosion resistance enable it to maintain good stability and safety in various harsh environments, making it the preferred material in many engineering projects. In the future, with the continuous advancement of science and technology and the continuous improvement of engineering needs, L245NS seamless steel pipe will be applied and promoted in more fields.
