Description

Technical Field

Traditional connection methods for three-way pipe fittings mostly rely on welding, threaded connection or flange connection. These methods are not only time-consuming and laborious during installation, but also have certain safety hazards, such as unstable welding quality and easy loosening of threads. Therefore, developing a new, convenient and reliable connection method for three-way pipe fittings has become an urgent need in the industry. Content of the Utility Model
