Four characteristics of alloy steel tee
Alloy steel tees are often used in pipeline connection.Here is a brief introduction to the four characteristics of alloy steel tee.
Alloy steel tee is generally a device used for regulating valve drainage.Concentric pipe with different diameters is beneficial to fluid flow,and the disturbance of fluid flow pattern is less at the time of changing diameters.
Alloy steel threaded equal tees
Gas and vertical flow of liquid pipes use concentric pipe with different diameters.Alloy steel tees are flat on one side,which is conducive to exhaust or drainage,and is convenient for driving and maintenance.Therefore,alloy steel tees are commonly used in horizontal liquid pipelines.
Alloy steel tees are formed by hot pressing or forging of steel.Its connection mode is butt welding directly between tees and steel pipes.The primary manufacturing specifications of alloy steel tees are generally ANSI/ASME B16.9,DIN EN 10253,GOST 17376,JIS B2311,KS B1541,MSS SP-43,GB/T 12459, GB/T 13401,SH3408, SH3409, HG/T 21635, HG/T 21631,SY/T 0510.
Alloy tees generally can be classified as equal-diameter tees and reducing tees. When the content of chromium in steel reaches about 1.2%, the oxygen effect of chromium and corrosive medium forms a very thin oxide film (self-passivation film) on the surface of steel. Alloy tees can prevent further corrosion of steel matrix. In addition to chromium, commonly used alloy elements include nickel, molybdenum, titanium, niobium,copper,nitrogen,etc,to satisfy different functions and requirements. Selection of production and processing technology for concentric tees ensures that good effect and function can be displayed.
