Carbon steel tee
山东群英会怎么玩Carbon steel tee is also a kind of pipe piece, usually have two kinds. Equal diameter tee, the two diameters are the same, and the branch tube is different from the other two diameters.
Carbon steel tee is pipe fitting and pipe connecting piece. It is also called pipe fitting or three-way pipe fittings, stainless steel, etc., three-way joint, which is used in the main pipe to branch the pipe.
Carbon steel tee is three cut, namely one import and two exits; Or two imported, one of the export of a chemical pipe, with t-shaped and y-shaped, with equal diameter pipe, and with a reducer, for three identical or different piping. The main function of tee is to change the direction of the fluid.
The corrosion resistance of carbon steel tee is due to chromium, but because chromium is one of the components of steel, the protection method is different. This tightly adhering rich chromium oxide protects the surface to prevent further oxidation. This layer of oxide is extremely thin, and through it can see the natural sheen of carbon steel tee, making carbon steel tee has a unique surface.
The performance of carbon steel tee depends mainly on the carbon content and microstructure of steel. Under annealing or hot rolling, with the increase of carbon content, the strength and hardness of the three pass are increased, while the plasticity and impact toughness decrease, the welding property and the cold bending are worse.
Classification of three - pass material of carbon steel:
1, 10 #, # A3, Q235A 20g 20g 20g 16Mn ASTM A234 ASTM A234 ASTM A403 etc.
2. The standard of GB/T12459-2005 is generally implemented in DN15 to DN800.
3。 The big one belongs to the seam welding, and the standard is GB/T13401-2005。
