The diameter of the pipe fitting cap is related to factors

　　Through the test surface, the diameter of the blank is bigger, and the volume of the blank will be larger in the process of processing, and his tangential stress is greater. If it is a thinner pipe fitting cap then his stress will be lost and there will be a wrinkle.

　　When the pipe fitting cap of the ellipsoid cap is launched, the diameter of the blank will be judged. If we meet the size of the En 10253-1316 Stainless Steel Pipe Fitting Cap, we have to make the diameter of the blank a little smaller. In the stamping, we also have to press the edge, and we have to make the force of the edge larger, which will make the loss of friction larger, and the pressure will also be lost. In addition, if the surrounding compression thickens the pipe fitting cap, then the tensile resistance becomes larger, which makes the pipe fitting cap thinner and easier to break.

　　We do not need to make the diameter of the blank bigger. The edge of the head is cut off when it is loved. It is not only a waste to the material, but also a large increase in the cost. If possible, we should enter and reduce the blank diameter of the pipe fitting cap. It is calculated that the diameter of the pipe fitting cap will be larger after the pipe fitting cap is unfolded, and there will be an error and a larger one. As a result, we can know that if the pipe fitting cap is used to determine the diameter of the blank, there will be a waste.
