Advantages of carbon steel seamless elbow

Carbon steel seamless elbow is a common elbow material that is cheap and easy to use. According to the standard, it is divided into: national standard, non-standard, international standard: German standard, Japanese standard, American standard, British standard elbow. According to the material, it is divided into: low carbon steel, high carbon steel, medium carbon steel, 20 steel (20g), Q235a, q235b, etc., carbon steel seamless elbows are characterized by relatively high carbon content; let’s take a look at the advantages of carbon steel seamless elbows for your reference.

The raw material of carbon steel seamless elbow is seamless steel pipe. The production process is round tube blank → heating → piercing → three-roll cross rolling, extrusion or continuous rolling → tube removal → sizing (or diameter reduction) → cooling → straightening →Hydraulic test (or flaw detection)→Marking→Storage. 45e (L) means a long radius 45 degree elbow, 45e (S) means a short radius 45 degree elbow, 90e (S) means a short radius 90 degree carbon steel elbow, 90e (L) means a long radius 90 degree elbow, 180 e (S) represents a short radius 180 degree carbon steel elbow, and 180 e (L) represents a long radius 180 degree elbow.

The principle for determining the heating temperature of carbon steel elbows is that the austenitization temperature of the material is above this temperature, and the principal compressive stress on the inner wall of the elbow is less than the yield limit of the material at this temperature. The higher the austenitization temperature of the material, the higher the heating temperature. , the higher the yield limit of the material, the higher the heating temperature will be.

advantage:

1. Carbon steel seamless elbows do not add any toxic substances, and the materials are entirely composed of carbon and hydrogen. Seamless elbow materials have been inspected by relevant national departments, and hygiene is guaranteed.

2. The weight of the carbon steel seamless elbow is only 1/10 of the weight of the steel pipe, which greatly reduces the transportation cost. You can imagine how light it is and is easy to install and construct.

3. The heat resistance of carbon steel seamless elbow is very good. When the working water temperature is 70°, the softening temperature is 140°. So there is no need to worry about its heat resistance at all.

4. The corrosion resistance of carbon steel seamless elbow is also very strong. Except for a small amount of hydrogenating agent, it not only does not rust, but also does not breed bacteria.

5. Good thermal insulation performance, everyone knows this. Because the thermal conductivity of seamless elbow material is very low, its thermal insulation is very good compared with thermal insulation materials.

6. Carbon steel seamless elbow has strong impact resistance. Because the impact strength is much stronger than other solid wall pipes, 1.3 times that of solid wall.
