Background
The heat exchanger is a device for realizing heat exchange between media, is widely applied to the fields of petroleum, chemical industry, food and other industrial production, and especially plays an important role in the petroleum and chemical industry. At present, a common pressure test mode for a tube head of a floating tube plate heat exchanger is generally to use an equipment shell as a pressurizing shell, a pressure test ring is manufactured to be used for fixing a fixed tube plate on the shell, a tube bundle extends out of a double-cylinder structure tool for a floating tube plate end of the shell, an outer cylinder is sleeved outside an inner cylinder, a baffle ring is arranged on the inner wall of the outer cylinder, a packing or an O-shaped ring is placed on the baffle ring, the packing or the O-shaped ring is pressed by using one end of the inner cylinder, and the inner cylinder is connected with the outer cylinder through a flange and a.
For some construction specific heat exchangers, for example: the two ends of the heat exchanger are tube plates, one end of each tube plate is fixed on a tube box flange through a cone flange, and the end tube plate is called a fixed tube plate; the other end is not connected to the shell and the end tube sheet is called a floating tube sheet. When being heated, the tube bundle and the floating tube plate can move freely in the shell, and the tube bundle can be drawn out, thereby being convenient for maintenance and replacement. After the fixed tube plate, the floating tube plate and the heat exchange tube are welded, a hydrostatic test is usually carried out on the tube head of the heat exchange tube, whether a welding seam between the heat exchange tube and the tube plates at two ends is leaked is detected, the special-form heat exchanger cannot utilize the original equipment shell and a common pressure test tool to carry out the hydrostatic test of the tube head because the fixed tube plate end cannot be fixed on the shell, the length of the tube bundle is smaller than that of the shell, and the floating tube plate end does not extend out of the shell, so that the pressure test tool is required to be manufactured according to the length and the diameter of the.
