Description of titanium WN welding neck flange
Titanium WN (welding neck) flange is a type of flange used in
piping systems to provide a connection point between two pipes. It
consists of a circular flat plate with a central hole, and a long
tapered hub that extends from the plate. The inner diameter of the
hub matches the inner diameter of the pipe, while the outer
diameter of the hub is larger than the outer diameter of the pipe.
The titanium WN flange is designed to be welded to the end of the
pipe, providing a strong and reliable connection. The tapered hub
of the flange helps to reduce stress concentration at the base of
the weld, improving the overall strength of the joint. The flat
plate of the flange provides a mounting surface for bolts, which
are used to attach the flange to another flange or piece of
equipment.
Titanium is an excellent material for use in WN welding neck
flanges due to its high strength, corrosion resistance, and
durability. It is particularly well-suited for use in harsh
environments where other materials may corrode or degrade over
time. Titanium WN flanges are commonly used in applications such as
the oil and gas industry, desalination plants, power generation,
and the food and beverage industry.

Type of titanium flange
Titanium flanges are used in various industries due to their
excellent strength, corrosion resistance, and durability. Here are
some common types of titanium flanges:
1.Weld Neck Flanges: Weld neck flanges are the most commonly used
type of flange in piping systems. They have a long tapered hub that
is welded to the pipe, providing a smooth transition between the
pipe and the flange. Titanium weld neck flanges are commonly used
in critical applications where high strength and corrosion
resistance are required.
2.Slip-On Flanges: Slip-on flanges have a bore slightly larger than
the outer diameter of the pipe, allowing the pipe to slip into the
flange. The flange is then welded to the pipe, providing a strong
and reliable connection. Titanium slip-on flanges are commonly used
in low-pressure applications where welding is not a concern.
3.Threaded Flanges: Threaded flanges have internal threads that
allow them to be screwed onto the pipe. They are commonly used in
small-diameter piping systems and low-pressure applications.
Titanium threaded flanges provide excellent corrosion resistance
and are commonly used in seawater and chemical processing
applications.
4.Blind Flanges: Blind flanges are used to close the end of a pipe
or a valve, providing a seal against pressure and preventing the
flow of fluid. Titanium blind flanges are commonly used in
applications where the pipe or valve needs to be closed temporarily
or permanently.
In summary, the most common types of titanium flanges are weld neck
flanges, slip-on flanges, threaded flanges, and blind flanges. The
choice of flange type depends on the specific application
requirements, such as pressure, temperature, and fluid
compatibility.
Application case of titanium WN welding neck flange
Titanium WN welding neck flanges can be used in various
applications where high strength, corrosion resistance, and
durability are required. Here are a few examples:
1.Oil and gas industry: In the oil and gas industry, titanium WN
welding neck flanges are used in offshore drilling platforms,
subsea pipelines, and other critical equipment. The excellent
corrosion resistance of titanium makes it an ideal material for use
in harsh environments.
2.Desalination plants: Desalination plants are used to remove salt
and other impurities from seawater, producing fresh water for
drinking and irrigation. Titanium WN welding neck flanges can be
used in desalination plants due to their excellent resistance to
saltwater corrosion.
3.Power generation: In power generation applications, such as
nuclear power plants, titanium WN welding neck flanges can be used
in critical systems, including cooling water systems and steam
turbines. The high strength and corrosion resistance of titanium
make it an ideal material for use in these applications.
4.Food and beverage industry: Titanium WN welding neck flanges can
be used in the food and beverage industry where hygienic and
corrosion-resistant materials are required. They can be used in
equipment such as tanks, pumps, and valves, ensuring the safe and
reliable transport of food and beverages.
In summary, titanium WN welding neck flanges are widely used in
various industries, including oil and gas, desalination, power
generation, and food and beverage, among others. The excellent
strength, corrosion resistance, and durability of titanium make it
an ideal material for use in harsh environments and critical
applications.
