Titanium Pipe Fitting Standards And Specifications
The titanium pipe fitting standard first appeared in the American Aerospace Standards. The only internationally available standard for titanium pipe fittings in the chemical industry is ASTM B363 [5]. It is also a document often followed in the international trade of titanium pipe fittings. ASTM B363 was established in 1961, the first revision was in 1978, and it was revised several times later (for example, in 83 and 87). The latest version was in 1995, which made the standard more complete.
In 1994, the Northwest Nonferrous Metals Research Institute issued the corporate standard Q/XB1507—94 "Titanium Butt Welding Seamless Pipe Fittings". It is warmly welcomed by the design department. The introduction of this standard represents the beginning of the standardization of titanium pipe fittings in my country. It is the main reference document for the production, distribution, design and construction of titanium pipe fittings in my country.
In order to enable the standard to better guide the standardized production, design and selection, procurement and distribution, installation and construction of my country’s titanium pipe fittings, the State Administration of Petroleum and Chemical Industry issued the "Titanium Butt Welding Seamless Pipe Fittings" industry on July 13, 1999 Standard. This standard was drafted by Quan Northwest Nonferrous Metal Research Institute. The standard number is HG/T3651-1999, which has been implemented on June 1, 2000. The dimensional tolerances of pipe fittings stipulated in this standard are equivalent to the American National Standard ANSI B16.9-1986 "Forged Steel Butt Welding Pipe Fittings" and my country's National Standard GB 12459-90 "Steel Butt Welding Seamless Pipe Fittings". The requirements for pipe fittings and finished products The material properties and surface quality of the pipe fittings are equivalent to the American Society for Testing and Materials standard ASTM B363-95 "Seamless and Seam Titanium and Titanium Alloy Butt Welding Pipe Fittings".
