1. When installing titanium and titanium alloy pipes, please pay attention not to contact or collide with iron materials when transporting and storing titanium and titanium alloy pipes.
2. The cutting of titanium and titanium alloy pipes should be made by mechanical methods, and the cutting speed should be low; when titanium welded pipes are cut or reground with grinding wheels, special grinding wheels should be used; flame cutting should not be used. The groove should be processed by mechanical methods.
3. Inert gas shielded welding or vacuum welding should be used for welding titanium and titanium alloy pipes. Oxygen-acetylene welding or carbon dioxide gas shielded welding should not be used, and ordinary manual arc welding should not be used.
4. When installing titanium and Grade 9 Ti3Al2.5V Titanium Tubes, it is not allowed to use iron tools and materials to knock and squeeze; rubber or soft plastic plates should be padded between the carbon steel supports and hangers and the titanium and titanium alloy pipes to make them Do not directly contact with titanium and titanium alloy pipelines; when the titanium and titanium alloy pipelines pass through walls and floors, casings should be installed, the gap should not be less than 10mm, and the insulation should be filled. The insulation should not contain iron impurities.
5. Titanium and titanium alloy pipes are not suitable for direct welding connection with other metal pipes. When the connection is required, a loose flange connection can be used. The non-metallic gaskets used are generally rubber gaskets or plastic gaskets, and the chloride ion content should not exceed 25ppm.
