Definition of radius of curvature for carbon steel elbows
The definition of the curvature radius of carbon steel elbow: the curvature radius of carbon steel elbow is a term used in the field of engineering, that is, the radius of bending, which expresses the degree of bending.
Carbon steel elbow bending radius: 45 degrees of air pipe carbon steel elbow turning radius is the bending radius by 0.785;90 degrees is the bending radius times 1.57;
The bending radius R of the carbon steel elbow of the pipe is the curvature radius corresponding to the center line of this section of the elbow.It is generally determined by multiples of pipe diameter.Such as: hot pressure elbow is generally one to two times the bend, fire simmering elbow is generally three to four times the bend.
Cable diameter R = 100, turning radius is 20 * R = 2000 mm, if the actual cable turn 90 ° bend, power cable in the transportation, installation or operation, should be strictly prevent flexion sprain and cable, cable small allowed bending radius and the ratio of outer diameter, shall not exceed the given value of table 1 table 1 the bending radius of the cable and the ratio of cable diameter.
Ring volume = 2x3.14x3.14 (r^2)Rr-- Ring radius r-- Ring volume = 2x3.14x3.14 ((r^2)-(r '^2))Rr' -- Inner circle radius of the ring 90,60,The volume of the elbow (elbow pipe) of 45 degrees is 1/4, 1/6 and 1/8 of the volume of the ring of the corresponding hollow pipe.Steel density engineering weight calculation according to 7.85 kg/cubic decimeter, density X volume = weight (mass).
