What are the unique properties of aluminum alloy pipe elbow

Aluminum alloy pipe elbow material is carbon steel elbow called carbon steel elbow. Carbon steel elbow in the pipeline system, is to change the direction of the pipeline pipe fitting. Carbon steel elbow is made of carbon steel elbow. Low carbon steel has good plasticity and low strength. After adding appropriate amount of carbon element, it will become hard. Elbow connection may need to bear very high tensile, compressive, torsional, shear strength, carbon steel elbow is a better choice.

Carbon steel elbow first according to its radius of curvature to be divided into long radius elbow and short radius elbow. The long radius elbow refers to the outer diameter of the pipe whose radius of curvature is equal to 1.5 times, that is, R=1.5D. Short radius elbow means that its radius of curvature is equal to the outer diameter of the pipe, i.e. R= 1.0d. (D is the diameter of the elbow, R is the radius of curvature. D can also be expressed as a multiple.

Corner to reasonable use, can need not need not, when I was using the corner although looks orderly, but corner form 90 degree connecting two wires, wire at which it is difficult to twitch, if it is more than two corners, wire can not move, in meet with line out of the question, can't take out line inspection or replacement, lead to route invalid, by contrast, pipeline, there is no such problem, although adornment effect is poor, but very practical.

Let the diameter of the bend be D, the bending radius of the bend be R, and the bending Angle of the bend be 90°. In order to reduce the error, the elbow is divided into four sections, and the bending Angle of each section is 30°. The first section and the last section are respectively 15° and can be divided into more sections according to the engineering accuracy requirements.

Here, we take the four sections as an example to make a simple description and explanation. First, we divide the 90° bend into the first section and the tail section into 15° each, and then divide the 60° in the middle into 30° in each of the two sections, making the bisector OA of the middle section, passing AB to make the section circle of the pipe, and the center of the circle is P
