Decarburization 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…
Read MoreHaving been in the steel pipe industry for many years, Xinyue has already transformed from a single steel pipe manufacturing & exporter to a first-class supplier of professional comprehensive services. Customer’s demand is the driving force behind Xinyue’s continuous innovation and self-improvement. Xinyue’s reputation attracts more and more EPC and oil company end user to establish close cooperation with…
Read MoreThe quality and performance of seamless pipes are determined according to needs. According to different needs, different element contents and types must be matched with them. (1) Carbon: The higher the carbon content, the higher the hardness of steel, but the worse its plasticity and toughness. (2) Sulfur: It is a harmful contaminant in steel. When steel with high…
Read MoreOil casing pipe is the lifeblood of keeping oil wells running. Due to different geological conditions, the downhole stress state is complex, and the comprehensive action of tension, compression, bending and torsional stress acts on the pipe body, which puts forward higher requirements on the quality of the casing itself. Once the casing itself is damaged for some reason,…

Read MoreThe hot-dip galvanizing process is a relatively stable and reliable steel surface treatment solution to resist environmental corrosion. There are many factors that affect hot-dip galvanizing, such as: steel substrate composition, surface state (such as roughness), substrate internal stress, geometry The thickness of the base material has a greater impact on the thickness of hot-dip galvanizing, and generally the…
