Theoretical weight of carbon steel elbow

Theoretical weight of carbon steel elbow  

Our company on the theory of carbon steel elbow pipe to make a brief introduction: the weight of carbon steel elbow is generally based on customer customized material, carbon steel elbow pipe wall thickness to calculate the weight of carbon steel elbow pipe, of course, the material and wall thickness refers to the comparison of the same size of carbon steel elbow pipe.  

Carbon steel elbow pipe fittings in the pipeline system, carbon steel elbow pipe fittings is to change the direction of the pipe, according to the Angle is divided into: 45 degrees, 90 degrees 180 degrees three long Angle, in addition, according to the needs of the project also includes 60 degrees and other abnormal Angle carbon steel elbow pipe fittings.  The difference between carbon steel elbow pipe fittings and stainless steel elbow pipe fittings is mainly the difference of material.  Carbon steel elbow pipe fittings can be directly welded in the process of use.  

Calculation formula of carbon steel elbow pipe fitting:  

Ring volume = 2x3.14x3.14 (r^2) r  

R -- the radius of the circle  

R-- radius of rotation of ring  

The volume of the middle hollow pipe ring = 2x3.14x3.14 ((r^2)-(r '^2)) r  

R '-- the radius of the inner ring  

The volume of 90, 60 and 45 degrees elbow (elbow) is 1/4, 1/6 and 1/8 of the corresponding hollow pipe ring volume respectively.  

The density of steel is calculated by 7.85 kg/cubic decimeter in engineering, density * volume = weight (mass).  

1. 180° elbow shall be calculated as shown in table 2, and 45° shall be calculated as 1/2;
