Both 15CrMoG boiler steel pipe and 15CrMoG high-pressure steel pipe involve the material 15CrMoG. The following is a detailed introduction to these two steel pipes:
First, details of the 15CrMoG boiler steel pipe
15CrMoG boiler steel pipe is an alloy high-pressure boiler steel pipe, which is an alloy steel. It is based on high-quality carbon structural steel, and one or more alloy elements are appropriately added to improve the mechanical properties, toughness, and hardenability of the steel. Products made of this type of steel usually need to be heat treated (normalizing or quenching and tempering); the parts and components made of it usually need to be quenched and tempered or surface chemically treated (carburizing, nitriding, etc.), surface quenching or high-frequency quenching before use.
According to the different chemical composition (mainly carbon content), heat treatment process, and use of 15CrMoG boiler steel pipe can be roughly divided into three types: carburizing, quenching tempering, and nitriding steel. This type of steel is mostly rolled (forged) into round, square, flat profiles and seamless steel pipes. It is mostly used to make important and larger parts and components in mechanical products, as well as high-pressure steel pipes and containers. It has better comprehensive mechanical properties than high-quality carbon structural steel.
Second, the details of 15CrMoG high-pressure steel pipe
15CrMoG high-pressure steel pipe is a seamless steel pipe. Due to its different manufacturing processes, it is divided into hot-rolled (extruded) seamless steel pipes and cold-drawn (rolled) seamless steel pipes. Cold-drawn (rolled) pipes are divided into round pipes and special-shaped pipes.
15CrMoG steel is a pearlite heat-resistant steel with high thermal strength (δb≥440MPa) and oxidation resistance at high temperatures, and has a certain resistance to hydrogen corrosion. Due to the high content of Cr, C, and other alloying elements in the steel, the steel has a more obvious tendency to harden and poor weldability.
In addition, 15CrMoG high-pressure steel pipes are recyclable, which is in line with the national strategy of environmental protection, energy saving, and resource conservation. National policies encourage the expansion of the application field of 15CrMoG high-pressure steel pipes.
Third, the application and standards of 15CrMoG boiler steel pipes and 15CrMoG high-pressure steel pipes
15CrMoG boiler steel pipes and 15CrMoG high-pressure steel pipes are widely used in various high-pressure, high-temperature, and corrosion-resistant occasions. They comply with a series of national and industry standards, such as GB53102008 (seamless steel pipes for high-pressure boilers). These standards specify the materials, manufacturing processes, performance requirements, etc. of steel pipes, ensuring the quality and reliability of steel pipes.
Fourth, summary
15CrMoG boiler steel pipes and 15CrMoG high-pressure steel pipes are both high-quality high-pressure steel pipe materials with excellent performance and a wide range of applications. They comply with national and industry standards, ensuring the quality and reliability of steel pipes. When selecting and using, the appropriate steel pipe material and specifications should be selected according to the specific use environment and requirements.
