Titanium flange hot processing should pay attention to details

1. The cutting of titanium and titanium alloy pipes should be carried out by mechanical methods, and the cutting speed should be kept at a low speed; When cutting or grinding titanium tubes with grinding wheels, special grinding wheels should be used; Flame cutting is not allowed. Grooves should be machined by mechanical methods.

2. Titanium and titanium alloy tubes should be careful not to contact or collide with iron materials during transportation and storage.

3. The welding of titanium and titanium alloy pipes should be done by inert gas shielded welding or vacuum welding. Can not use oxygen acetylene welding or carbon dioxide gas welding, can not use ordinary manual arc welding.

4. Titanium and titanium alloy pipes should not be welded directly with other metal pipes. When it is necessary to connect, you can use the ring flange connection. The non-metallic gasket used is generally rubber or plastic gasket, and the chloride ion content should not exceed 25ppm.

5. Titanium and titanium alloy pipes shall not be hit or squeezed with iron tools and materials during installation; Rubber or soft plastic sheets should be inserted between carbon steel support and titanium and titanium alloy pipes to prevent direct contact between titanium and titanium alloy pipes; When a titanium or titanium alloy pipe passes through a wall or floor, the casing installation gap should be no less than 10mm, and the pipe should be filled with thermal insulation materials. Insulation materials should not contain iron impurities.
