Threaded tee is a pipe fitting used in industrial pipeline systems to achieve medium diversion through threaded connections. The main body is made of stainless steel materials such as 304 and 316, and can be divided into equal diameter and reduced diameter types according to the size of branch and main pipes. Its structure includes two straight through openings and a vertical/angled branch pipe, which complies with domestic and foreign industrial standards such as GB/T14626 and ASME B16.11, and is suitable for pipeline systems in the fields of petroleum, chemical, and power. The patented technology improves the sealing and installation flexibility of traditional threaded tees, such as the groove design allowing for 360 degree rotation installation, and the clamping structure achieving mixed connection scenarios
