How to identify the magnetism of stainless steel welded pipes?Stainless steel welded pipes are also widely used in production. Many people only know that stainless steel welded pipes have anti-oxidation and anti-corrosion properties, but few know that stainless steel welded pipes can be magnetic. So, how to identify the magnetism of stainless steel welded pipes?…
Anti-corrosion is a measure to alleviate or reasonably prevent corrosion or mold caused by the chemical and photo-catalytic effects of internal and external substances or by the metabolic activities of microorganisms. This technology is applicable to civil, general public buildings, and anti-corrosion construction applications. Metals are subject to a series of damages due to the…
① Chemical composition of steel: The chemical composition of steel is one of the most significant factors influencing the performance of seamless steel pipes, and it is also the main basis for determining the process parameters of tube rolling and the heat treatment parameters of steel pipes.a. Alloy elements: Intentionally added, depending on the application….
Difference 1: Different raw materials used for productionThe materials for seamless steel pipes include ordinary and carbon structural steel (such as Q215-A to Q275-A and 10 to 50 grade steel), low alloy steel (such as 09MnV, 16Mn, etc.), alloy steel, and stainless acid-resistant steel, etc.The welded pipe is made by rolling and shaping the steel…
In the application of stainless steel pipes, stainless steel pipes are one of the most common raw materials. However, many people do not know how to select stainless steel pipes. So, how can we distinguish the quality of stainless steel pipes? Let’s take a look together with the stainless steel pipe manufacturer.Methods for distinguishing the…
There are also times when stainless steel welded pipes are of poor quality during production, which is a very normal phenomenon. We should promptly carry out repair work. The steps for repairing different problems are also different. Now let’s talk about how to operate the repair of stainless steel seamless pipes.When steam leaks from the…
304 stainless steel pipe is the most commonly used stainless steel pipe material in our daily life. 304 stainless steel pipe is a grade of stainless steel produced in accordance with the American ASTM standard. 304 is equivalent to 0Cr19Ni9(0Cr18Ni9) stainless steel in China. 304 contains 19% chromium and 9% nickel. 304 stainless steel pipe…
The surface of stainless steel plates is smooth and clean, with high plasticity, toughness and mechanical strength. They are resistant to corrosion by acidic, alkaline gases, solutions and other media. It is an alloy steel that is not prone to rust, but it is not absolutely rust-free. Stainless steel plates refer to steel plates that…
