Knowledge About Carbon Steel Seamless Elbow

Apr 27, 2020

1. The manufacturing process can be divided into push the system, pressing, forging, casting and so on.

2. In manufacturing standards it can be divided into GB, electricity standard, ship standard, of the standard, water standard, American standard elbow, the German standard, Japanese standard, the Russian standard and so on.

3. According to its radius of curvature of points: it can be divided into long radius elbows and short radius elbow. Long radius elbow refers to its radius of curvature equal to 1.5 times the outer diameter of the pipe, that R = 1.5D; short radius elbow refers to its radius of curvature equal to the pipe diameter, ie R = 1.0D.

Carbon steel seamless elbow in the process should pay attention to the problem

Carbon steel elbow determining principle of the heating temperature is less than the elbow inner wall of the main stress yield limits of the material at this temperature austenitizing temperature or higher, and when to push the system. Material austenitizing temperature, the higher the heating temperature; the higher the yield limit of the material temperature, the heating temperature is higher

What are the advantages of carbon steel seamless elbow

1. Seamless elbow all the material is composed of carbon, hydrogen composed of two elements, will not add any toxic substances, and seamless elbow material is the result of the detection of relevant state departments, so it can be assured of health sex.

2. Seamless elbow weight of just one-tenth of the steel pipe, you can imagine how light it is, but also greatly reduces the cost of transportation, at the time of installation and construction is also very convenient.

3. Heat resistance seamless elbow, but good none, Why? For example, when the working temperature is 70 ° when the softening temperature is 140 °. So it's nothing to worry about heat problems.

4. Seamless elbow corrosion resistance is also very strong, not only will not rust, will not breed bacteria, of course, but a few of the hydrogenating agent addition.

5. Good insulation properties, which should be known to everyone. Because of the low thermal conductivity seamless elbow material, so with respect to insulation performance is very good.

6. Impact strength properties seamless elbow more stronger than other solid-wall pipe, compared with a solid wall, then it is 1.3 times. So it has a strong impact resistance.
