A forged tee for natural gas pipelines comprises a tee body; a three-pipe connection of the tee body is provided with a compressive member, and surface connections of the compressive member and three pipes are provided with relief arcs. The forged tee meets the requirements on corrosion resistance, strength and safety; in order to impart high temperature resistance to the tee and high-content carbon dioxide for corrosion resistance, double-phase stainless steel is used; in order to impart high pressure resistance to the tee, the finite element analysis method is performed on stress analysis; in order to impact solider inner structure to the tee, forging is performed; at a place of flow speed changing, crossing line chamfers are made to reduce stress which is concentrated and great, and the compression member which is square is added to reduce the damage of the tee caused by stress.
