From the perspective of the male force gradually bad cap flat cap conical cap dealers from hemispherical cap, but the difficulty of making point of view, good manufacturing gradually. GB150 and relevant standard head is not reasonable to define the thickness of the conical cap manufacturers, mainly in the container and head thickness requirements after forming a spherical cap prices, forming convex head thickness and thermal requirements shall reel less than the nominal thickness less steel negative deviation (δn-C1), which may lead to the design and manufacture of twice the thickness increase on the basis of the design to ensure that the thickness of the molded thickness. To do this, who put forward the concept of a minimum thickness forming: "hot roll or convex cylinder head Forming the need to ensure the thickness, its value is not less than the design thickness." That should be marked in the name of the designer and minimum thickness forming thickness (ie the design thickness δd) in the drawing, which makes manufacturing units can be combined with manufacturers to decide whether thinning rounded amount based on the design and manufacturing process of the original design. This definition is the thickness of the cut-off in 2013 and marked a popular method of international pressure vessel industry, has its own rationale, but in our current standards in the following two issues to be resolved
