Maintenance and storage of titanium pipe and titanium alloy welded pipe:

1、Titanium alloy pipes and elbows shall be inspected regularly to keep the surface clean and remove the dirt. They shall be stored in an indoor ventilated place without stacking or outdoor storage.

2、When the ball valve, stop valve and gate valve of titanium alloy pipe elbow are used, they are only used for full opening or full closing, and are not allowed to be used for regulating flow, so as to prevent the sealing surface from erosion and accelerate wear.

3、The gate valve and upper thread stop valve are equipped with reverse sealing equipment, and the hand wheel is screwed to the surface of the highest head to ensure that it will not rust or fall. Keep the environment of titanium pipe fittings for storing titanium alloy pipes, titanium elbows, titanium big and small heads, titanium tees, etc. dry and ventilated, keep the surface of pipes and pipe fittings clean and neat, and store them accurately.

Precautions for installation and transportation of titanium pipes and fittings:

1. When titanium and titanium alloy pipes are installed, the titanium pipe manufacturer shall pay attention not to contact or collide with iron materials during transportation and storage.

2. Titanium and titanium alloy pipes shall be cut mechanically at a low speed. When titanium pipes are cut or repaired with grinding wheels, special grinding wheels shall be used. Flame cutting is not allowed. The groove should be machined by mechanical method.

3. Inert gas or vacuum welding shall be used for the welding of titanium alloy welded pipe, oxygen acetylene welding or carbon dioxide gas welding shall not be used, and ordinary manual arc welding shall not be used.

4. During the installation of titanium and titanium alloy pipes, iron tools and materials shall not be used to knock or squeeze; rubber plate or soft plastic plate shall be padded between carbon steel supports and hangers and titanium and titanium alloy pipes to prevent them from directly contacting with titanium and titanium alloy pipes; when titanium and titanium alloy pipes pass through walls and floors, casings shall be added with a clearance of not less than 10 mm and filled with insulation, which shall not be included There are iron impurities.

5. Titanium and titanium alloy pipes should not be directly welded with other metal pipes. When connection is needed, looper flange can be used. The non-metallic gasket used is generally rubber or plastic gasket, and the chloride ion content shall not exceed 25ppm.
