1. During the transportation and storage of titanium and titanium alloy pipes, attention should be paid not to contact or collide with iron materials.

2. The cutting of titanium and titanium alloy pipes should be done using mechanical methods, and the cutting speed should be at a low speed; When cutting or grinding titanium pipes with grinding wheels, specialized grinding wheels should be used; Flame cutting is not allowed. The groove should be machined using mechanical methods.

3. Titanium and titanium alloy pipes should be welded using inert gas shielded welding or vacuum welding. Oxygen acetylene welding or carbon dioxide gas shielded welding cannot be used, and ordinary manual arc welding cannot be used.

4. During the installation of titanium and titanium alloy pipes, iron tools and materials should not be used to strike or squeeze them; Rubber or soft plastic sheets should be inserted between carbon steel supports and hangers and titanium and titanium alloy pipelines to prevent direct contact with titanium and titanium alloy pipelines; When titanium and titanium alloy pipelines pass through walls and floors, sleeves should be installed with a gap of no less than 10mm, and insulation materials should be filled. The insulation materials should not contain iron impurities.

5. Titanium and titanium alloy pipes should not be directly welded to other metal pipes. When connection is required, a looped flange connection can be used. The non-metallic gaskets used are generally rubber or plastic gaskets, and the chloride ion content should not exceed 25ppm.
