Seamless pipe weight calculation table, the actual component of seamless pipe is calculated according to the nominal size of steel and density (formerly known as the proportion) of the calculated component called the actual component. This length and size of steel, cross-sectional area and size tolerances are indirectly related.
Seamless steel tube weight calculation
For steel pipes, I believe we all know that we can see it in house construction or decoration. In addition, there are many other uses of seamless steel pipe. Today, I will share with you the weight calculation method of seamless steel pipe.
What is seamless steel pipe?
Seamless steel pipe with hollow section, a large number of used for conveying fluid pipeline, such as conveying oil, natural gas, gas, water and some solid material pipeline. Compared to the steel pipe and round steel solid steel bending torsional strength phase at the same time, the weight is lighter, is a kind of economic cross section steel, widely used in the manufacture of structural and mechanical parts, such as petroleum drill pipe, auto transmission shaft, bicycle frame and construction of steel scaffolding is used with steel pipe manufacturing annular parts, such as can improve material utilization, simplifying the manufacturing process, material saving and processing time, Such as rolling bearing ring, jack sleeve, etc., has been widely used in steel pipe to manufacture.
The difference between theoretical weight and actual weight of seamless steel pipe
The theoretical weight of seamless steel pipe is calculated according to the nominal size and density of steel. This is directly related to the length and size of the steel, the section area and the allowable size deviation. Due to the allowable deviation of steel in the manufacturing process, the theoretical weight calculated by the formula differs from the actual weight to some extent, so it is only used as a reference for estimation. The actual weight of seamless steel pipe refers to the actual weight of steel to the actual weight, the actual weight is accurate than the theoretical weight.
Calculation formula of seamless steel tube weight
Calculation formula of steel pipe theory, including seamless steel pipe, welded pipe, unit: kg/m
W=0.02466*S (D-S) D= outer diameter S= wall thickness
The formula for calculating the theoretical weight of common profiles is m=F×L×ρ
M -- mass Kg; F -- Sectional area m2; L -- length m; Density of rho - * Kg/m3
Ordinary seamless steel tube weight calculation formula kg/m=(outer diameter mm- wall thickness mm)* wall thickness mm, the weight calculation formula per meter is in accordance with 0.02466× tube thickness x (outer diameter - tube thickness) to calculate, as long as the tube thickness, outer diameter and length into the formula, you can know the specific weight is how much. Different types of seamless steel pipe, wall thickness and diameter are different.
