Titanium TH Flange Class 150 ANSI/ASME for Chemical Industry
Titanium threaded flanges are pipe end fittings made of non-ferrous
titanium or titanium alloys. They utilize threaded connections
rather than welding, using the internal bore of the flange machined
to form pipe threads. Advantages include ease of installation and
maintenance, and they are suitable for piping systems where welding
is not permitted, particularly in low-pressure environments.
Titanium threaded pipe flanges are widely used in piping systems in
industries such as chemical processing, petroleum refining,
offshore engineering, power generation, pharmaceuticals, and food
processing. They are particularly well-suited for handling highly
corrosive media such as hydrochloric acid, sulfuric acid, and
seawater. Titanium's high corrosion resistance allows it to
maintain structural integrity and sealing reliability in harsh
environments, significantly reducing maintenance costs and
extending equipment life. Furthermore, compared to traditional
stainless steel or carbon steel flanges, titanium flanges offer
lower weight, making them valuable for high-end applications
requiring weight reduction.
Titanium alloy threaded flanges are available in sizes from NPS 1/2
to NPS 6, and custom designs are also available based on customer
specifications or drawings. Our titanium flanges are manufactured
in strict accordance with ASME international standards to meet the
diverse requirements of our global customers.

Frequently Asked Questions
1. What are the outstanding performances of titanium threaded
flange in terms of corrosion resistance?
Titanium threaded flanges have extremely strong resistance to
corrosive media such as seawater and chloride ions. Their corrosion
resistance far exceeds that of stainless steel and carbon steel,
and they are especially suitable for harsh environments such as
marine and chemical industries.
2. Do titanium threaded flanges need additional anti-rust measures?
No need. Titanium threaded flanges can be used for a long time
without coating or cathodic protection, avoiding the risk of rust
and significantly reducing maintenance requirements.
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.
