The standard of titanium pipe fittings first appeared in the United States aerospace standards. The only standard that can be found internationally for titanium machined pipe fittings in the chemical industry is ASTM B363 . It is also a document that is often followed in the international trade of titanium pipe fittings. ASTM B363 was established in 1961, the first modification was in 1978, and it has been revised many times since then (such as 83 years and 87 years). The latest version is 1995, which makes the standard more complete. .
In 1994, the Northwest Nonferrous Metal Research Institute issued the enterprise standard Q / XB1507 — 94 “Titanium Machining Seamless Pipe Fittings”. Was warmly welcomed by the design department, the introduction of this standard represents the beginning of the standardization of titanium pipes in China. It is the main reference document for the production, distribution, design and construction of titanium pipe fittings in China.
