3.Where does the lightweight advantage of titanium flanges lie?
Titanium has a strength close to that of steel, but its density is only 60% of that of steel, which enables it to significantly
reduce the weight of equipment in fields such as aerospace and shipbuilding while maintaining high load-bearing capacity.
4.How does titanium flange perform in low-temperature environments?
Titanium flanges can still maintain excellent toughness in ultra-low temperature environments (such as liquid nitrogen and
liquid oxygen), making them an ideal choice for cryogenic engineering.
5.How is the high-temperature resistance of titanium flanges?
Titanium alloys (such as TA2 and TA9) can maintain stable mechanical properties at high temperatures of 300-500℃, and
some materials can even withstand higher temperatures for A short period of time.
6.How do titanium flanges resist high-temperature oxidation?
At high temperatures, a dense oxide film forms on the surface of titanium, which can effectively isolate oxygen and prevent
further oxidation of the material.
7.Why is the service life of titanium flanges longer than that of stainless steel?
In corrosive environments, the lifespan of titanium flanges can be over ten times that of stainless steel, and they require
almost no maintenance, resulting in a lower total life cycle cost.
8.Why are titanium flanges still economical despite their high initial cost?
Although the initial purchase cost of titanium flanges is relatively high, their extremely long service life and very low
maintenance requirements significantly reduce the long-term usage cost, making their overall economic performance
better.
9.Are titanium flanges suitable for the pharmaceutical and food industries?
Yes. Titanium has non-toxic and harmless biocompatibility, and its material purity is high, fully meeting the strict hygiene
requirements of fields such as pharmaceuticals and food processing.
10.How are the processing and welding properties of titanium flanges?
Titanium flanges support various welding methods such as TIG welding and plasma welding, with high weld strength. They
can also be designed in interface forms such as flat welding, butt welding, and threaded welding, to meet the requirements
of different pipeline systems.
