One of the materials often used in the construction site of construction projects is small diameter square steel pipe, which has a very wide range of applications, such as scaffolding, formwork support and other places. Today, let's learn about the small caliber Jinan square tube that can be used as a pipe for steelmaking and oxygen blowing.
Small diameter square tube is a kind of long steel with hollow section and no seams around. It is also called "bread tube" because of its hollow section. The specification is mainly a square with a side length of 50mm and a rectangle with a side length of 100mm.
The small diameter square pipe is used as the pipe for steelmaking and oxygen blowing, and the steel pipe for smelting and oxygen blowing is generally welded steel pipe with 8 specifications ranging from 3/8 inch to 2 inch. It is made of or Q195-Q235 steel strip. In order to prevent corrosion, some are aluminized.
It is developed on the basis of S series products and combines the actual needs of current electric arc furnace steelmaking. It is characterized by high refractoriness, low consumption and convenient operation. In electric arc furnace steelmaking, oxygen or other gases are transported, and steel is melted and refined in the electric arc furnace.
According to different welding methods, steel pipes for smelting oxygen blowing with small diameter square tubes can be divided into arc square tubes, high-frequency or low-frequency resistance square tubes. Electric welded steel pipe is used for oil drilling and production and machinery manufacturing, and can be used as water gas pipe, etc. Large diameter straight seam square pipe is used for high-pressure oil and gas transmission.
The strength of flares produced by manufacturers is generally higher than that of straight seam square tubes. Narrow billets can be used to produce square tubes with larger diameters, and billets with the same width can also be used to produce square tubes with different diameters.
However, compared with the straight seam pipe with the same length, the weld length increases by 30~100%, and the production speed is low. Therefore, small diameter square tubes are mostly used for small diameter square tubes, and spiral welding is mostly used for large diameter square tubes.
The small diameter square tube can be used as the tube for steelmaking and oxygen blowing as described above. I hope to give you some help. Please come to our website for more related matters http://www.jnhxtcg.com Consult and understand!
