jobsCareersWhy should Q345B seamless steel pipe be surface treated, and the new Q345B seamless steel pipe steel grades are also diverse. The surface treatment of Q345B seamless steel pipe is one of the important factors to choose the life limit of steel pipe anti-corrosion application. The standard for strong combination of anti-corrosion layer and Q345B seamless steel pipe. Certified by scientific research institutions, the life of the anti-corrosion layer depends on factors such as the type of coating used in the construction of the project, the quality of the coating and the natural environment. Therefore, it is not optimistic, according to the Q345B seamless steel pipe surface anti-corrosion layer standard, continue to explore and summarize, and constantly improve the Q345B seamless steel pipe surface treatment method. Its soothing reactivity has a good impact in real-world commodity applications. And it all stems from the sound technicality of its seamless splicing process. The whole process of Q345B seamless steel pipe poisoning is first to pickle and passivate Q345B seamless steel pipe. In order to better remove the compound on the surface of Q345B seamless steel pipe, the appearance of Q345B seamless pipe has high corrosion resistance. After pickling passivation, it is cleaned in a solution tank according to ammonium chloride or magnesium chloride solution or a mixture of ammonium chloride and magnesium chloride, and then sent to the dip plating tank. Carbon steel pickling passivation solution combines pickling and passivation into one, which greatly improves labor productivity. The pickling passivation solution is very convenient to use and operate. The tank body is cleaned with small and medium-sized carbon steel pipe fittings, or operated by brush or spray, and then rinsed with clean water. The use temperature is 5-30 degrees Celsius, and the pickling passivation can be achieved for about 5-15 minutes. Passivation, sometimes referred to as "pickling", occurs when the corrosion products of the metal due to the action of the medium have a dense structure, forming a thin film that closely covers the surface of the metal, thereby changing the surface state of the metal and causing the electrode potential of the metal to change. Jumps in the positive direction and becomes corrosion-resistant passive. Exhibits corrosion-resistant performance. This film is called a passivation film, and the passivation of the metal can also be a spontaneous process.
