L290M pipeline steel pipe quality grade (PSL2) is made of pipeline steel plate, and when the steel pipe is a spiral steel pipe, it is not allowed to have a joint weld, which is mainly used for steel pipes for gas, water and oil transportation pipelines in the oil and gas industry. The yield strength of the steel pipe of L290M pipeline is 290-495, and the yield ratio is not more than 09. The delivery status of the steel plate is hot-rolled or controlled. The grade of pipeline steel, L is the symbol of the total elongation stress, and L290 means the total elongation stress of 290MPa, which is commonly used to manufacture pressure pipelines such as spiral welded pipes. The L290M pipeline steel pipe MB in the pipeline steel pipe is explained as: M (deformation heat treatment), which is a deformation process, in which the deformation is completed within a certain temperature range, so that the material has certain properties that cannot be achieved or repeated by heat treatment alone. If it is subsequently heated to 580 degrees Celsius, the intensity value will be reduced. To meet the basic quality requirements, on this basis, the requirements from the overall increase become Class B requirements, such as toughness and non-destructive testing, and in some special purposes, the quality and experimental requirements for steel pipes are very strict as Class C. L290M pipeline steel pipe implements GB T9711-2017PSL2 oil pipeline steel pipe standard. Pipeline steel is mainly used to manufacture pipelines that transport oil, natural gas and other media, especially high-pressure pipelines need to ensure a high safety factor, so compared with conventional products, pipeline steel should not only have the characteristics of height, high toughness, good welding performance, etc., but also need to have low Baucinger effect and good low anti-cracking performance.
L290m longitudinal seam steel pipe seamless steel pipe has good compressive performance, and the welded pipe is generally about 10 megapascals. Seamless tubes perform better and, of course, higher. L290M longitudinal seam steel pipe seamless pipe of different materials can be used in many fields and has a wide range of applications. The seamless design of alloy pipes ensures that there will be no leakage in the process of pipeline transportation, whether it is to transport oil or natural gas, the actual installation process of this type of pipeline material is also very simple, and a few simple steps can be easily done, alloy pipes are often widely praised in the market, becoming a pipeline material with surging demand in the market, and the production scale level of its manufacturers is also expanding. In recent years, the use rate of alloy pipes has been increasing, and at the same time, more people have begun to realize that L290M longitudinal seam steel pipes can have a positive impact on my life. L290M longitudinal seam steel pipe steel pipe is widely used in many fields, especially in the field of transportation, as a cost-effective pipeline material, the development prospect of alloy pipe will be broader and broader in the future. In the future production of the demand is very large, the role is also - very - large, the pipeline is also common, with the large-scale economic construction, L290M longitudinal seam steel pipe steel pipe in the pipeline will play a better and better role.
