Precautions for the installation, use and welding of titanium pipes

1. Titanium alloy pipes and elbows should be inspected regularly to keep the surface clean and remove dirt. They should be stored indoors in a well-ventilated area, not piled up or stored outdoors.

2. When using ball valves, stop valves, and gate valves for titanium alloy pipes, they should only be fully opened or closed. They should not be used for regulating flow, as this can cause erosion of the sealing surface and accelerate wear.

3. Gate valves and threaded stop valves have reverse-sealing devices inside. The handwheel should be rotated to the top position to ensure that the surface does not rust or deteriorate. Maintain a dry and well-ventilated environment for storing titanium alloy pipes, titanium elbows, titanium reducers, titanium three-way valves, etc. Keep the surfaces of the pipes and pipe fittings clean and neat, and store them according to the correct method.

Precautions for the installation and transportation of titanium and titanium alloy pipes:
1. When installing titanium and titanium alloy pipes, titanium pipe manufacturers should avoid contact with iron materials and collisions during transportation and storage.

2. For the cutting of titanium and titanium alloy pipes, mechanical methods should be used. The cutting speed should be low. When using a grinding wheel to cut or polish titanium pipes, a special grinding wheel should be used. Flame cutting is not allowed. Grooves should be processed by mechanical methods.

3. Titanium alloy welded pipes should be welded using inert gas protection welding or vacuum welding. Oxygen-acetylene welding or carbon dioxide gas protection welding should not be used. Ordinary manual arc welding is not allowed.

4. When installing titanium and titanium alloy pipes, do not use iron tools or materials to strike or squeeze. Rubber plates or soft plastic plates should be placed between carbon steel supports and hangers and titanium and titanium alloy pipes to prevent direct contact. When titanium and titanium alloy pipes pass through walls or floors, sleeves should be installed. The gap should not be less than 10mm and insulating materials should be filled. Insulating materials should not contain iron impurities.

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