Carbon steel elbow
Carbon steel elbow is used in common a kind of material, the price is cheap, easy to use, according to the material can be divided into: low carbon steel, medium carbon steel, high carbon steel, 20 # steel q235a, q235b, is characterized by relatively high carbon content, carbon steel elbow manufacture non-standard can be divided into: gb, non-standard, gb standard, Germany standard, Japanese standard, American standard, British standard elbow, etc.
Carbon steel elbow is divided into two kinds: straight seam elbow and seamless elbow. The raw material of carbon steel seamless elbow is seamless steel pipe. The main production process is round tube billet, heating, perforation, three-roll cross rolling, continuous rolling or extrusion, pipe removal, sizing, cooling, straightening, hydraulic test, marking, storage.Carbon steel elbow wall thickness grade, carbon steel elbow is divided into long radius elbow and short radius elbow.
The carbon steel elbow heating temperature is determined according to the material, and the main compressive stress of the inner wall of the elbow is less than the yield limit of the material at temperature. The higher the temperature of the material, the higher the heating temperature, the higher the yield limit of the material, the higher the heating temperature, the higher the heating temperature to provide the advantages of seamless elbow.
The material of the seamless elbow is composed of carbon and hydrogen, and it will not add any toxic substances. And the material of the seamless elbow has been tested by the relevant departments, so the use of the carbon steel elbow can be assured.
The weight of the seamless elbow is only one tenth of the steel pipe, you can imagine how light the seamless elbow is, but also greatly reduce the cost of transportation, in the installation and construction is also very convenient.
