Titanium And Titanium Alloy Pipe Installation Considerations
Jun 04, 2018

When transporting and depositing titanium and titanium alloy tubes, care should be taken not to contact or collide with ferrous materials.

(1) Titanium and titanium alloy tubes should be cut by mechanical methods, and the cutting speed should be suitable at low speeds. When cutting or grinding titanium tubes with special wheels, special grinding wheels should be used; no flame cutting is allowed. Grooves should be machined.

(2) Titanium and titanium alloy tubes are to be welded by inert gas or vacuum welding. Oxygen-acetylene welding or carbon dioxide gas welding cannot be used, nor can manual welding be used.

(3) Titanium and titanium alloy pipes shall not be struck and pressed with iron tools and materials; rubber plates or soft plastic plates shall be interposed between the carbon steel supports and hangers and the titanium and titanium alloy pipes. It shall not be in direct contact with titanium and titanium alloy pipelines; titanium and titanium alloy pipelines shall be installed with sleeves when passing through walls and floors, and the gap shall not be less than 10mm, and the insulator shall be caulked, and the insulation shall not contain iron impurities.

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