Quiz 2: What is the standard number for titanium welded pipes?

National standard: GB/T 26057—2010; Japanese standard: TIS9634

GB/T 26057-2010

What standards are used for the design of large-diameter titanium pipes and fittings? https://bbs.hcbbs.com/thread-1018164-1-1.html (Source: Haichuan Chemical Industry Forum) GB/T 26057-2010: Welded tubes of titanium and titanium alloys (maximum outer diameter ~38 mm); GB/T 3624-2010: Seamless tubes of titanium and titanium alloys (maximum outer diameter ~110 mm); HG/T 3651-1999: Butt-welded seamless titanium fittings (maximum nominal diameter DN300). What standards are used for the design of titanium pipes with a DN greater than 100, and titanium fittings with a DN greater than 300? Thank you!

I just saw it; I turned off the computer. I’ll send it to you tomorrow

Titanium pipe fittings are currently specified in GB/T27684-2011, and those with a diameter larger than DN300 are available. For titanium pipes, I haven’t been able to find any corresponding standards at the moment; however, there is a construction specification and acceptance standard for titanium pipes, namely SH3502-2000. Common standards for pressure vessels: https://bbs.hcbbs.com/thread-1195490-1-1.html (Source: Haichuan Chemical Industry Forum). Standards related to titanium: 17. GB/T16598-1996 “Titanium and titanium alloy ingots and rings”; 18. GB/T6611-2008 “Terms and microstructural diagrams for titanium and titanium alloys”; 19. GB/T6614-1994 “Castings of titanium and titanium alloys”; 20. GB/T3620.1-2007 “Designations and chemical compositions of titanium and titanium alloys”; 21. GB/T3620.2-2007 “Chemical compositions and compositional tolerances of processed products made of titanium and titanium alloys”; 22. GB/T3621-2007 “Plates of titanium and titanium alloys”; 23. GB/T3622-1999 “Strips and foils of titanium and titanium alloys”; 24. GB/T3624-2010 “Tubes of titanium and titanium alloys”; 25. GB/T3625-2007 “Tubes of titanium and titanium alloys for use in heat exchangers and condensers”; 26. GB/T2965-2007 “Rods of titanium and titanium alloys”

This is a small-diameter welded pipe with a maximum outer diameter of 38 mm

For titanium welded pipes larger than DN150, there are currently no specific standards available. The ones that are relatively similar are these two: JB/T4745, Welded Titanium Vessels SH3502, and Specifications for the Construction and Acceptance of Titanium Pipelines
