We use stainless steel seamless pipes many times now, and many customers face a lot of problems when selecting materials, looking at the uneven prices on the market and related problems, there is no final solution. Here are some tips to share with you, so as to improve the cost-effectiveness of products when selecting finished products in the later…
Read MoreProduction methods Stainless steel tube according to the production method is divided into two categories of stainless seamless pipe and stainless welded pipe, stainless seamless steel pipe can be divided into hot-rolled tube, cold-rolled tube, cold-drawn tube and extrusion pipe, cold drawing, cold rolling is the second Processing; welded pipe is divided into straight seam welded pipe and spiral welded pipe. Section shape…
Read MoreComparison of ERW pipe and seamless pipe (SMLS): (1) Superior tube blank quality Compared with the tube blank of SMLS steel pipe, the design of chemical composition of high frequency welded pipe (ERW) is more scientific and reasonable. ERW special steel grades are characterized by high purity. Through de-S, de-P, degassing, Ca treatment and other methods, the content of…
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 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 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…
