1. Titanium alloy pipes and elbows should be regularly inspected to keep the surface clean, remove dirt, and store them in a ventilated place indoors, not stacked or stored in the open air.
2. The ball valves, stop valves and gate valves of titanium alloy pipe elbows are only fully opened or fully closed, and are not allowed to adjust the flow rate to prevent the sealing surface from being eroded and accelerated wear.
3. The gate valve and the upper thread prevent the valve from having reverse sealing equipment. The hand wheel is turned to the surface of the uppermost head to ensure that it will not rust and fall. Keep the titanium pipe fittings such as titanium alloy pipes, titanium elbows, titanium heads, and titanium tees dry and ventilated. Keep the surfaces of pipes and fittings clean and neat, and store them accurately.
Matters needing attention in the installation and transportation of titanium pipes and fittings:
1. Installation of titanium and titanium alloy pipes When transporting and depositing titanium and titanium alloy pipes, titanium pipe manufacturers should take care not to contact or collide with ferrous materials.
2. The cutting method of titanium and titanium alloy tubes should be mechanical, and the cutting speed should be low speed. When cutting or grinding titanium tubes, special grinding wheels should be used; flame cutting should not be used. The groove should be processed by mechanical methods.
3. Welding of titanium alloy welded pipe should use inert gas shielded welding or vacuum welding. Oxygen-acetylene welding or carbon dioxide gas shielded welding cannot be used, nor can 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 inserted to make them Do not directly contact with titanium and titanium alloy pipelines; when passing through walls and floor slabs, the titanium and titanium alloy pipelines should be installed with a sleeve, the gap should not be less than 10mm, and the 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-metal gasket used is generally rubber or plastic, and the chloride ion content should not exceed 25ppm
