Read MoreThere are five main methods for detecting surface defects of square and rectangular tubes: 1. Eddy current inspection Eddy current testing includes basic eddy current testing, far-field eddy current testing, multi-frequency eddy current testing, and single-pulse eddy current testing. Using the eddy current sensor to magnetically induce metal materials, the type and shape of the surface defects of the…
Read MoreFor carbon steel pipe (CS pipe), it should be degreased first and then pickled, because grease is insoluble in acid solution. If pickling is performed first, neither the oil stains nor the rust covered by the oil stains can be removed. Degreasing pickling method for carbon seamless steel pipe: At present, the tank immersion method is often used in…
Read MoreDecarburization is a phenomenon in which the surface carbon content of the steel pipe (CS seamless pipe) decreases during the heat treatment process. The essence of decarburization is that the carbon atoms in the steel tube react with the furnace atmosphere such as hydrogen or oxygen at high temperature to form methane or carbon monoxide. Decarburization is the result…
Read MoreThe pickling solution used in the pickling process of seamless square tubes is generally a mixture of various acids, mainly sulfuric acid, nitric acid and hydrofluoric acid, etc. These mixed acids are highly corrosive and have strong oxidizing properties. The temperature is also relatively high, which puts forward high requirements on the corrosion resistance of anti-corrosion materials. There are…
