1. Commonly used titanium and titanium alloy steel pipes
2. When installing titanium and titanium alloy pipes during transportation and storage of titanium and titanium alloy pipes, be careful not to contact or collide with ferrous materials.
(2) The cutting of titanium and titanium alloy pipes should be performed by mechanical methods, and the cutting speed should be at a low speed; when cutting or grinding titanium pipes, special grinding wheels should be used; flame cutting should not be used. The groove should be processed by mechanical methods.
(3) Welding of titanium and titanium alloy pipes should use inert gas shielded welding or vacuum welding. Oxygen-acetylene welding or carbon dioxide gas shielded welding should not be used, nor should ordinary manual arc welding be used.
(4) When installing titanium and titanium alloy pipes, iron tools and materials shall not be used to knock and squeeze; between the carbon steel supports, hangers and titanium and titanium alloy pipes, rubber plates or soft plastic plates shall be It is not in direct contact with titanium and titanium alloy pipes; when titanium and titanium alloy pipes pass through walls and floor slabs, bushings should be added, the gap should not be less than 10mm, and insulation should be filled, and the insulation should not contain iron impurities.
(5) Titanium and titanium alloy pipes should not be directly welded to other metal pipes. When connection is needed, loose flange connection can be used. The non-metallic gasket used is generally rubber or plastic, and the chloride ion content should not exceed 25ppm.
