The axial section of the stainless steel clamp is concave. On the two upper and lower surfaces on the inner side, there are inclined planes. The inclination angle of these planes relative to the horizontal plane should be less than the friction angle, usually ranging from 5° to 7°. At the groove area, to alleviate stress concentration, the larger the turning radius, the better.
The head and the flange of the cylinder connected by the stainless steel clamp both have raised shoulders. The inclination angle of the inclined plane on the raised shoulder is the same as that of the clamp's inclined plane. When tightened, several clamp pieces are firmly connected together. By relying on the action of the cooperating inclined planes, the head and the cylinder flange are brought closer together, thereby achieving sealing.
Stainless steel clamps are generally divided into two types. One is connected by bolts. This type of clamp can be further divided into half-matching type, three-piece matching type, or more-piece matching type. They are fastened by connecting bolts. The other type is a quick-release clamp. It is fastened by two pairs of bevel gears through two bolts.
