Ordinary tee; three links to the production method can be divided into the top system of three links, to suppress the three links, forged tee, butt welded tee, casting tee, etc .. Tee by the shape of two, And the diameter of the three links is equal to the size of the three holes. Reduced tee is a section with a small branch of the tube, obviously, two large size is the main, the middle of the small size is out of the branch . In the pure oxygen pipeline, the pressure is generally. Second, the three-way welding, four-way GB12459 inch Nominal diameter DN end of the outer diameter of the center to the end D1 D2 CMA Series B Series A Series B Series 1/2
