In the soda ash industry, heat exchangers and tray plates are often made of titanium, as are valves
The last edit to this post was made by diwu0205 on 2011-2-24 at 09:45; in the caustic soda/PVC system, the valves and pipes used for high-temperature caustic solutions are made of pure nickel； In TDI (toluene diisocyanate) synthesis plants, nickel-based valves and pipes such as Monel and Hastelloy are used in many places ； In acetylene (C2H2) plants, many of the high-pressure components are made of titanium pipes and valves ；
It should be corrected that there are no pipes or valves made of titanium in the acetylene installation
Reply to 4# diwu0205: In acetylene plants, there is no high-pressure section either, as the acetylene plant I was responsible for constructing didn’t have one
Nickel-based alloy and titanium equipment, pipes, and valves for PTA plants.
In the titanium dioxide industry using chlorination methods, nickel-based alloys are widely used, and titanium materials are also applied to some extent.
On the 4th floor, do you know that there are many different processes for producing acetylene? If you use the calcium carbide method, it’s impossible to obtain special materials, because the process is too simple, understand? You can go and ask at the acetylene unit of Plant 103 at CNPC Jilin Petrochemical Company. If you want, I can give you their contact information. I sold titanium check valves, globe valves, and plug valves from the Dutch company Redpoint there for over 100,000 euros, and they are still working well to this day. What I want to say is that if you want to draw a conclusion, it’s better to understand the process first. Don’t just draw conclusions as if you’re the moderator – do you really have the ability to do that? There’s also my name, which I decide myself. If you have the authority to delete me, then go ahead and do it. With moderators like you around, I don’t even need to use HaiChuan anymore.
Titanium is widely used, and can be found in chemical processing equipment, anti-corrosion equipment, and other types of equipment.
Recently, we worked on a formic acid project for Luxi Chemicals; the client required many titanium (TA10) valves, in total over 150 of them.
Titanium materials are used in chlor-alkali processes, heat exchangers, and sodium hypochlorite cooling. Also, the methanol recovery tower used in glycine production is lined with titanium, and its internal components are made of titanium as well.
