Equal diameter hot pressing pipe tee forming process the thickness of the equal diameter tee and the reducing tee is used to express the detailed reducing main type, while the American Standard reducing tee uses Sch to express the pressure of the reducing tee. Before the reproduction of American Standard reducing tee and pressing cold extrusion, we must implement the wall thickness of reducing tee before further cold extrusion of reducing tee. If we don't know the wall thickness of the reducing tee, what if we make the cold extrusion reducing tee to meet the customer's requirements. This is a huge difference in wall thickness between our most common national standard reducing tee and American Standard reducing tee.
