Introduction to Titanium Flange

Titanium flange is a kind of part made of non-ferrous metal titanium or titanium alloy to connect the pipe with the pipe, which is connected to the pipe end. There are holes on the titanium flange, and bolts make the two flanges tightly connected. The flange is sealed with gasket. Flange pipe fittings refer to the pipe fittings with flange (flange or adapter). It can be formed by threaded connection or welding. The flange connection is composed of a pair of flanges, a gasket and several bolts and nuts. The gasket is placed between the two flange sealing surfaces. After the nut is tightened, the specific pressure on the gasket surface reaches a certain value, and the deformation occurs, and the uneven parts on the sealing surface are filled, so that the connection is tight. According to the structure type, there are titanium lap Joint flange, titanium weld neck flange, titanium threaded flange and titanium blind flange, etc.

Titanium Flange Performance Characteristics

A novel type of metal is titanium. Its characteristics depend on the presence of impurities including carbon, nitrogen, hydrogen, and oxygen.

Titanium Flanges are Very Strong
Only 60% as dense as steel, titanium alloy has a density of roughly 4.51g/cm3. Pure titanium is quite similar in density to regular steel. Some extremely strong titanium alloys are stronger than many alloy structural steels. As a result, titanium alloy has a substantially higher specific strength (strength/density) than other metal structural materials.

High Thermal Strength
Titanium alloy can operate for extended periods at 450–500 °C while still maintaining the needed strength at mild temperatures.

Flange Made of Titanium Resists Corrosion Well
The corrosion resistance of titanium alloy is much better than that of stainless steel when used in humid environments and seawater environments. It has strong resistance to pitting corrosion, acid corrosion, and stress corrosion, as well as excellent corrosion resistance to alkali, chloride, chlorine organic materials, nitric acid, sulfuric acid, and other acids.

Titanium Flange Performs Well at Low Temperatures
Low and ultra-low temperatures allow titanium alloy to preserve its mechanical characteristics. Titanium alloys like TA7, which have excellent low-temperature characteristics and relatively little interstitial material, can maintain some plasticity to – 253 °C. Titanium alloy is a crucial low-temperature structural material as a result.

The Advantages of Titanium Flanges

Titanium flanges stand out as exceptional components in various industries, owing to a host of advantages that make them a preferred choice for critical applications. These advantages stem from the unique properties of titanium, which offer a range of benefits in terms of performance, durability, and overall system efficiency. In this section, we’ll delve into the key advantages of titanium flanges and why they are highly sought after.

Exceptional Corrosion Resistance

One of the most remarkable advantages of titanium flanges is their exceptional resistance to corrosion. Unlike many other metals, titanium forms a stable oxide layer on its surface when exposed to air or moisture. This oxide layer acts as a protective barrier, preventing further corrosion from occurring. This property makes titanium flanges highly desirable for industries that deal with corrosive environments, such as chemical processing, offshore drilling, and marine applications. The ability to resist corrosion ensures that piping systems remain robust and reliable over time, reducing maintenance costs and minimizing downtime.

This advantage has revolutionized the medical field, enabling the development of implants that can replace damaged bones or joints. The corrosion resistance of titanium ensures the longevity of these implants, offering patients improved quality of life and reduced need for replacements.

Types of Titanium Flanges

Titanium Weld Neck Flange

A titanium weld neck flange is a type of titanium flange designed to transfer stresses to the pipe to reduce high stress concentrations at the base of the titanium flange. Compared with other types, titanium weld neck flanges are know for their tapered hub and gentle transition from flange thickness to pipe wall thickness. They are deformation-resistant, and are normally used for high pressure piping system, high or low temperature conditions.
Advantage:
The connection is not easy to be deformed, the sealing effect is good, and it is widely used. It is suitable for pipes with large fluctuation of temperature or pressure or pipes with high temperature, high pressure and low temperature. It is also used for pipes conveying expensive medium, inflammable and explosive medium and toxic gas.
Shortcomings:
The titanium flange with neck butt welding is bulky, cumbersome, expensive and difficult to locate. Therefore, it is easier to bump in transportation.

Titanium Slip On Flange

Titanium Slip on flange is a type of titanium flange which slides over the end of steel piping and then welded in place.Because the pipe slips into the titanium flange before welding,it has a low hub.The inside and outside of the titanium flanges are both welded,resulting in sufficient strengh and no leak. Yaang slip on flanges can be easily fitted and welded into different pipes.It is perfect for lower pressure applications.
Advantage:
It is convenient for welding or easy to process or require strong strength, such as plastic pipes, glass steel pipes and so on. Easy construction, such as connecting the titanium flange bolt hole corresponding to facilitate the alignment or prevent future replacement of titanium equipment flange bolt hole change. When the price is high, save money. When the pipe material is special, the titanium flange with the same material is expensive.
Shortcomings:
Accept low pressure.
The strength of the weld ring is low (especially below 3mm thickness).

Titanium Threaded Flange

A titanium threaded flange is used for special circumstances with their main advantage being that they can be attached to the pipewithout welding. Sometimes a seal weld is also used in conjunction with the threaded connection. This special type of titanium flange is generally used for high pressure piping system, yet smaller diameter applications. Obviously, the larger the titanium flange is, the harder the ability to machine a thread would be.
Advantage:
Compared with titanium flat welding flange or titanium butt welding flange, titanium thread flange has the characteristics of easy installation and maintenance, and can be used in some pipelines which are not allowed to be welded on site. Titanium flange has enough strength, but it is not easy to weld, or welding performance is not good, can also choose titanium thread flange.
Shortcomings:
It is recommended that no titanium threaded flange be used to avoid leakage when the temperature changes rapidly or the temperature is higher than 260 C below -45 C.

Titanium Blind Flange

A titanium blind flange is a popular type of titanium pipe flanges.It has no bore in the center,and is primarily used to close the ends of piping systems.This titanium flange premits easy access to a line once it has been sealed.It sometimes can be machined to accept a nominal sizes pipe to which a threaded or welded reduction is being made. Yaang titanium blind flanges are available in various sizes and material for you to choose from.

Titanium Spectacle Flange

A titanium spectacle blind, also known as a titanium figure-8 blind-is generally a piece of metal that is cut to fit between two titanium pipe flange and usually sandwiched between two gaskets. A spectacle blind is often made from two metal discs that are attached to each other by a small section of steel. The shape is similar to a pair of glasses or “spectacles” – hence the name spectacle blind. One end of the blind will have an opening to allow flow through the pipe during operation and the other end is solid to block flow during maintenance. They are generally installed as a permanent device to separate process piping systems.

Titanium Integral Flange (Titanium Long Weld Neck flange)

A titanium Integral flange which is also called titanium long weld neck flange (LWN flange), is used for high pressure situations, titanium integral hub weld neck flanges are used and for very high pressure cases titanium long welding neck flanges are preferred. In this case, the weld are far from the ring to avoid bending stresses and weld stress being combined.

Titanium Plate Flange

A titanium plate flange is a flat, circular disk that is welded onto the end of a steel pipe and allows it to be bolted to another pipe. Typically used in fuel and water pipelines, the two titanium flange plates will be bolted together with a gasket in between them. The titanium flange plate will have bolt holes all around the perimeter and will be used to create junctions, tees and joints.

Titanium Non-Standard Flange

Size of titanium flange
Titanium flange: 1/4″-160″, DN8-DN4000
Titanium flange Pressure-Temperature Class (Service Rating)
Titanium flange are classified as per their pressure-temperature ratings which are designated as 150#, 300#, 400#, 600#, 900#, 1500# and 2500#. Large diameter titanium flanges that is 24” to 60” are available up to 900# class. Pressure-temperature ratings are maximum allowable working gage pressures in the bar & the temperatures in degrees Celsius.
Higher the rating, heavier the titanium flange and can withstand higher pressure and temperature. When the temperature goes up, the pressure goes down, and vice versa. Please note that different material has different pressure ratings.

How to Select the Right Flanges?

Apart from the type, you have to pay attention to some important characteristics when selecting the best flange for your specific applications. These include the size, the pressure class and the material. Let’s take a closer look to some of them.

Selecting the Size
To select the flange size, you need to refer to ANSI/ASME standards. These standards provide the sizing of the flange for the specific pipe diameter that will be connected to the flange. They usually include tolerances together with requirements and recommendations for flange bolting and flange gaskets.

Pressure Class
The pressure class makes reference to the pressure and temperature capacity of the flange. The term is used interchangeable with others, such as “pressure rating”, “class”, “#”, “Lb” or “Lbs”. ANSI/ASME standards are also applicable, and according to ANSI/ASME B16.5, there are seven flange pressure classes: 150, 300, 400, 600, 900, 1500, and 2500. These values are tightly related to sizing too. While two flanges may have the same bore size and the same material, having a higher class means it is bigger, heavier and more robust to withstand higher temperatures and pressures depending on the material. For example, ASME B16.34 takes care of the class for the most common flange materials which are carbon, alloy and stainless steels.

Selecting Material
The usual recommendation is to use a flange made of the same material as the pipes and fittings that will be connected to the flange or at least a compatible alloy. For example, in the case of titanium piping, the best choice would be titanium flanges or zirconium flanges. The idea is that the chemical composition of the materials does not create undesired reactions, especially when in contact with process fluids. ASTM standards apply for the specifications and requirements of the materials. ASTM standards assign a grade for easy identification of the material and describes the chemical composition in percentages. Common ASTM specifications for flanges are A105, A182 and A350. For titanium flanges, the ASTM standard gives specifications such as B363 and B381.

A: The main aim with flanges is to increase strength. They can also provide stabilisation or guidance. Plus, they can transfer the contact force with things like plumbing and fittings. One thing that is vital is that a flange must be strong and durable. With that in mind, it is essential to use the right material. Titanium flanges are really good here. They are one of the most common titanium machined parts. The metal has impressive strength so it can cater for high stress applications. Parts will also last a long time. Another huge advantage is the corrosion resistance. Titanium is known to be highly resistant, able to withstand a number of corrosive elements. This includes acids, alkaline materials, hydrogen, oxygen, and sulfur dioxide. As a result, it is an excellent choice for plumbing and pipework that has to move these resources. Plus, it can withstand marine and aerospace conditions. Titanium also has the distinction of having the best strength to weight ratio of any metal. That is really useful in a number of applications. What it can mean is you are adding less weight to pipelines and structures. In things like aerospace, it can mean a big improvement in performance. Specifically with a focus on titanium machined parts, the metal is a great option because it is good overall when it comes to formability and workability. Hot and cold working will not affect the mechanical properties. You can also use a number of methods to weld titanium.

The medical industry uses titanium fasteners as biophilic metals that are robust and not easily deformed and used for fixing clinical fractures and dislocations.
When building nuclear reactors, titanium is required for many pipelines, components, and other parts, and titanium fasteners are no exception. Ideally suited for fastening electronic equipment to electronic devices, titanium fasteners are nonmagnetic, strong, and lightweight.

Q: Is titanium stronger than steel bolts?

A: The strength and low weight of Titanium make it exceptionally unique, and some grades of Titanium can be anywhere from two to four times stronger than Stainless Steel. These features make Titanium ideal in some aerospace, medical and military applications. Titanium Fasteners are resistant to saltwater, making them suitable for use in maritime applications. They are also resistant to almost every chlorine or chloride solution, including chlorite, hypochlorite, chlorate, perchlorate and chlorine dioxide. If the chlorine is used with the absence of water though, or as a gas, this can cause rapid corrosion. Titanium screws and fixings are used in applications where a high strength to weight ratio, excellent resistance to stress corrosion cracking and high corrosion resistance are needed. A point to note: Whilst Titanium has excellent chloride resistance, it reacts badly to strong acids like hydrochloric acid or sulfuric acid, which attack the protective passive layer that Titanium forms when exposed to oxygen. This can cause corrosion.

Q: What are titanium screws used for?

A: It is more widely used in various industries. Ordinary stainless steel screws are more resistant to compression than titanium screws under high pressure environments. Therefore, titanium alloys are selected for aerospace metals, and titanium screws are used as the connection.

Q: Why are titanium bolts so expensive?

A: Casting or forging titanium drives its price up because these need to be done in an inert atmosphere such as helium or argon. Titanium will burn in an atmosphere of nitrogen as well as one of oxygen (this is where that gold-colored titanium nitride comes from that they use for coating drill bits).

Q: Do titanium bolts need anti-seize?

A: When it comes to using titanium bolts, it is important to choose the right lubricant to ensure that the bolts perform at their best and have a long lifespan. One of the best options for lubricating titanium bolts is a high-quality anti-seize lubricant.
