What is the purpose of Q345C seamless steel pipe

　　Q345C seamless steel pipe is a kind of seamless steel pipe. Alloy pipe is divided into seamless pipe for structure and high-pressure heat-resistant alloy pipe.

　　It is mainly different from the production standard and industry of alloy tube. The mechanical function of Q345C alloy tube is modified by annealing and tempering. Meet the required processing conditions. Its function is higher than that of the ordinary seamless steel pipe. The chemical composition of the alloy pipe contains more Cr. It has the function of high temperature resistance, low temperature resistance and corrosion resistance.

　　The common carbon seamless pipe does not contain alloy components, and may have few alloy components. The reason why alloy pipes are widely used in petroleum, aerospace, chemical, power, boiler, military and other industries is that the mechanical functions of alloy pipes are changed and adjusted.

　　① No matter what steel pipe is carbon steel pipe, it is just that the carbon content of steel pipes of different specifications is different, and whether other trace elements are added to form steel pipes with special performance, such as stainless steel pipes

　　② Ordinary carbon steel pipes are very easy to rust in humid and corrosive environments, so surface treatment is usually required. The general treatment includes galvanizing, plastic plating, painting anti-corrosion paint, etc. Galvanizing is divided into hot galvanizing and cold galvanizing. The processing process is different. Hot galvanizing has better corrosion resistance and longer service life than cold galvanizing, but the price is high

　　③ Steel pipes are divided into welded steel pipes and seamless steel pipes according to different processing technologies. Generally, the steel pipes we use are welded steel pipes, and the seamless steel pipes are rarely used. Please refer to the design requirements, design documents, or consult the designer.
