Advantages of carbon steel seamless elbow

Advantages of carbon steel seamless elbow

Carbon steel seamless elbow is a very common material used in elbow, cheap, easy to use. According to the material is divided into: low carbon steel, medium carbon steel, high carbon steel, No. 20 steel (20g), q235a, q235b, etc., characterized by a relatively high carbon content; According to the standard is divided into: national standard, non-standard, international standard: German standard, Japanese standard, American standard, British standard elbow.

The raw material of carbon steel seamless elbow is seamless steel pipe, and the main production process is round tube billet → heating → perforation → three-roll skew rolling, continuous rolling or extrusion → tube stripping → sizing (or reducing) → cooling → straightening → hydraulic test (or detection) → marking → storage. schxx is the wall thickness grade, 90e(s) indicates a short radius 90 degree carbon steel elbow; 90e(l) represents a long radius 90 degree bend; 45e(l) represents a long radius 45 degree bend; 45e(s) stands for short radius 45 degree elbow; 180e(s) represents a short radius 180 degree carbon steel elbow; 180e(l) represents a long radius 180 degree bend;

The principle of determining the heating temperature of carbon steel elbow is that the austenitizing temperature of the material is above, and the main compressive stress of the inner wall of the elbow is less than the yield limit of the material at this temperature. The higher the austenitizing temperature of the material, the higher the heating temperature; The higher the high temperature yield limit of the material, the higher the heating temperature

1. The material of the seamless elbow is all composed of two elements: carbon and hydrogen, absolutely no toxic substances will be added, and the material of the seamless elbow has been tested by the relevant departments of the state, so it can be assured of its hygiene.

2. the weight of the seamless elbow is only one-tenth of the steel pipe, you can imagine how light it is, but also greatly reduce the cost of transportation, in the installation and construction is also very convenient.

3. seamless elbow heat resistance is good, why do you say so? For example, when the working water temperature is 70°, the softening temperature is 140°. So there is no need to worry about its heat resistance.

4. seamless elbow corrosion resistance is also very strong, not only will not rust, but also will not breed bacteria, of course, in addition to a few hydrogenating agents.

5. good insulation performance, this should be known to everyone. Because the thermal conductivity of the seamless elbow material is low, it is very good relative to the thermal insulation performance.

6. The impact strength of the seamless elbow is much stronger than that of other solid wall tubes, which is 1.3 times higher than that of solid wall tubes. So it has very strong impact resistance.

7. another point is to mention that the service life of the stamping elbow is very long, it is said that it can reach more than 50 years, because it is under rated temperature and pressure, so that it not only emits radiation, emits ultraviolet light, but also makes the product never fade
