Application and manufacturing process of carbon steel tee

　　Carbon steel pipe fitting tee is located on the intersecting line between the main pipe and the branch pipe. The shape and position are more complex than the butt weld, and the quality of the weld is not easy to control when welding. According to statistics, the leakage rate of this kind of Carbon Steel Butt Weld Seamless Pipe Fitting Tee seam accounts for 80% of all welding seam leakage rate, the main defects are incomplete penetration, blowhole, slag inclusion, etc..
