Seamless steel pipe knowledge: Steel pipe network introduced 27simn seamless steel pipe

November 19, 2018

27simn seamless steel tubes, ie 27SiMn seamless steel tubes, are one of the materials for seamless steel tubes. The carbon content is between 0.24 and 0.32%. The simn single row is because of the five elements (carbon C, silicon Si and manganese). In Mn, phosphorus P, and sulfur S, the content of silicomanganese is about 1.10 to 1.40%. 27simn Seamless Pipe is suitable for power plant, boiler plant, chemical industry, car, ship accessories.
27simn seamless steel theory weight formula seamless steel tube per meter weight W=0.02466*S(DS)
Symbol Meaning: D = Outer diameter S = Wall thickness calculation example: For a seamless Steel Pipe with an outside diameter of 60mm and a wall thickness of 4mm, calculate the weight per m.
Weight per m=0.02466*4*(60-4)=5.52Kg
