The stainless steel tee has a main pipe and a branch pipe perpendicular to the main pipe and connected to the main pipe on one side of the main pipe. A valve is set at the corner where the main outlet direction intersects with the branch pipe outlet direction. The valve is provided with a circular valve disc, and the closed state of the lumen is sealed with the inner wall of the lumen, which simplifies the pipeline layout, saves the number of pipeline components, is convenient for operation, and is convenient for pipeline branch maintenance and sectional supply of each branch. The utility model not only has the function of a traditional pipe fitting tee, but also plays the role of a double station valve, that is, the output of the main pipe and the branch pipe can be closed at will, the other is in a stable working state, and the output flow ratio of the main pipe and the branch pipe can be changed arbitrarily, which can be realized by adjusting the angle of the valve plate in the pipe cavity. Tee can be used to change the direction of fluid, as well as water pipelines, oil pipelines and various liquid chemical material pipelines. It is mainly used in medicine, water conservancy (water-saving irrigation, water supply and drainage), energy (oil, natural gas, nuclear energy) and construction projects.
Forging method. Machining flanges through forging can be divided into two types: free forging and die forging. Free forging involves compression processing under a forging press
