    Introduction to Steel

    Stainless steel pipe (Stainless Steel) is a kind of hollow long strip cylindrical steel. Its scope of application is used as a pipeline for conveying fluid. It is mainly used in petroleum, chemical industry, medical treatment, food, light industry, mechanical instrument and other industrial transportation pipelines, as well as mechanical structure components. Stainless steel pipe is made of steel billet of acid and heat resistance, which is heated, perforated, fixed diameter, hot rolled and cut.

    Classification

    Classification of stainless steel pipe: stainless steel seamless steel pipe and stainless steel welded steel pipe (sewn steel pipe) basic two categories. According to the shape of the outer diameter of the steel pipe, it can be divided into round pipe and special-shaped pipe. The circular steel pipe is widely used, but there are also some square, rectangular, semicircular, hexagonal, equilateral triangle, octagonal and other special-shaped steel pipes.

    For steel pipes under fluid pressure, hydraulic test and ray inspection are carried out to test their pressure resistance and quality. No leakage, soaking or expansion occurs under the specified pressure. Some steel pipes are also required to carry out crimping test, flaring test, flattening test and so on according to the standard or requirements of the demand side.

    Seamless stainless steel pipe, also known as stainless steel seamless pipe, is made of steel ingot or solid pipe billet through perforation, and then hot rolled, cold rolled or cold dial. The specification of seamless steel pipe is expressed by outer diameter * wall thickness millimeter number.

    304 stainless steel pipe full name SUS304 stainless steel pipe.

    SUS304 stainless steel pipe belongs to the stainless steel pipe of American grade, the domestic grade is equivalent to 0 Cr19Ni9 stainless steel pipe, usually replaced by 0 Cr18Ni9.

    The rust-proof mechanism of stainless steel is that alloy elements form dense oxide film, insulate oxygen contact and prevent further oxidation. So stainless steel is not "stainless ".

    There may be several reasons for the rusting of 304 materials:

    Chloride ions exist in 1. use environment.

    Chloride ions exist widely, such as salt, sweat, sea water, sea breeze, soil and so on. Stainless steel in the presence of chloride ions in the environment, corrosion quickly, or even more than ordinary low carbon steel.

    Therefore, the use of stainless steel environment requirements, and often need to wipe, remove dust, keep clean and dry.

    316 and 317 stainless steel (317 stainless steel properties see below) are molybdenum-containing stainless steel. The molybdenum content in 317 stainless steel is slightly better than that in 316 stainless steel. Because of the molybdenum in the steel, the total performance of the steel is better than that of 310 and 304 stainless steel. At high temperature, when the concentration of sulfuric acid is less than 15% and higher than 85%,316 stainless steel has a wide range of applications. 316 Stainless steel also has good chloride erosion properties, so it is usually used in the marine environment.

    With the development of social economy, stainless steel pipe has been widely used. Will certainly bring new changes in various fields.

    Theoretical Weight of Stainless Steel Tube: W= Outer Diameter - Wall Thickness x x0.02491. Wall Thickness

    Since the invention of stainless steel at the beginning of this century, stainless steel has combined the image of modern materials and the outstanding reputation in architectural applications, which has made its competitors envy. Stainless steel does not produce corrosion, pitting, corrosion or wear. Stainless steel is also one of the highest strength materials in building metal materials. Because stainless steel has good corrosion resistance, it enables structural components to permanently maintain the integrity of engineering design. Chromium-containing stainless steel also integrates mechanical strength and high extensibility, and is easy to process and manufacture components, which can meet the needs of architects and structural designers.
