How to select titanium pipe specifications
Thread Content
For titanium pipes and fittings used for brine and wet chlorine, how should the diameter and wall thickness be selected? Which standards can provide guidance on this?
The selection of titanium pipes requires determining the pipe diameter and wall thickness based on factors such as the properties of the medium being transported, pressure, and temperature. Reference can be made to GB/T3624-2010 \"Tubes of titanium and titanium alloys\" and HG/T3651-2016 \"Design codes for chemical equipment and pipelines made of titanium and titanium alloys\" when making a selection. It needs to be determined based on the actual operating conditions and design requirements. .
Recommendations for titanium pressure vessels: GBT 3624-2023 for seamless tubes of titanium and titanium alloys, GBT 27684-2011 for seamless and welded fittings of titanium and titanium alloys
Thank you for sharing! According to GBT3624, the maximum outer diameter of seamless tubes is 110 mm. Does this mean that titanium seamless tubes cannot have a larger diameter?
Fittings can reach DN1200, and what is the maximum outer diameter of GBT3624 seamless pipes – 110 mm?
Fittings can be welded, that is, made by welding titanium steel plates, and sealed titanium tubes can also be formed from titanium plates, with larger dimensions possible. GBT3624 refers to seamless pipes, which can have smaller dimensions. Finally, you can understand by looking at the names of the two standards above.

What’s bothering me now is the wall thickness; I have a DN400 titanium tube in my project and I’m not sure what thickness to choose for it, as the pressure is slightly positive. If the standard wall thickness specified in GBT27684 is followed, it would have to be 9 mm thick, which seems too thick.
