Description

A take over structure for titanium steel composite sheet equipment
Technical Field
The invention belongs to the technical field of connection of connecting pipes of titanium steel composite plate equipment, and particularly relates to a connecting pipe structure for titanium steel composite plate equipment.
Background
The extremely low solubility of iron in titanium causes severe embrittlement of weld joints formed by fusion welding of iron-based materials and titanium materials, and loss of pressure bearing and corrosion resistance. Therefore, in the manufacturing process of the titanium steel composite plate equipment, the welding joint does not allow the mutual fusion of the coating titanium material and the base steel material, and the indirect welding method is adopted in the current common practice. For the connecting pipe of the titanium composite board equipment, the commonly adopted treatment method comprises the following steps: the method comprises the steps of locally stripping a coating titanium material at the position, close to the welding position of a connecting pipe, of a shell, forging the connecting pipe by using the same type of material of a titanium composite plate base material, welding a titanium steel composite ring plate serving as a flange sealing surface at the end part of a flange of the connecting pipe, covering a titanium lining plate with a certain thickness on the inner wall of the connecting pipe after the connecting pipe is welded with the titanium composite plate shell base material, completely covering the surface of the connecting pipe, which is possibly contacted with corrosive media, of the connecting pipe but not welded with the connecting pipe by using the titanium lining plate, welding the top end of the titanium lining plate with the coating of the titanium steel composite plate serving as the flange sealing surface, forming the bottom end of the titanium lining plate according to the intersecting surface of the connecting pipe and the shell, welding the coating of the titanium steel composite plate shell, and achieving isolation of the base material and internal corrosive operation media.
The conventional treatment method for the titanium steel composite board equipment connecting pipe mainly depends on the welding reliability of the titanium lining board for the anti-corrosion protection of the connecting pipe. In fact, titanium materials are very active and are very easy to oxidize at high temperature, welding is greatly influenced by environment, welding method and welding process, and if the titanium materials are not properly treated, the welding quality of the titanium lining plate cannot be guaranteed. If the titanium lining plate has welding defects, the strong corrosive operating medium breaks through the barrier of the titanium lining plate and reaches the gap between the titanium lining plate and the inner wall of the connecting pipe, and the corrosive medium directly corrodes and damages the connecting pipe because the titanium lining plate and the connecting pipe are not welded. The corrosion damage phenomenon is very easy to ignore under the shielding of the titanium lining plate, if the structure is not improved, the corrosion damage of the connecting pipe finally endangers the safe operation of equipment, threatens the long-term operation of the device, and causes unnecessary potential safety hazard and economic loss.
