What is Titanium Flange?
A titanium flange is a type of component which is utilize to join pipes that are attached to pipe ends and are constructed of the non-ferrous metal titanium or a titanium alloy. The titanium flange has holes, and bolts firmly fasten the two flanges together. The gasket is utilize to seal the flange. Pipe fittings with flanges are known as flange pipe fittings (flange or adapter).
Many various industrial applications call for the use of titanium flanges. Providing a safe attachment point between two pieces of metal or other materials is the most typical application for titanium flanges. For this reason, titanium flanges are frequently employ in plumbing applications to join pipes and other components together. Titanium flanges can take a lot of pressure because of their extreme strength without accidentally being harmed or destroyed. They may be move around without any issues because they are also incredibly light in weight.
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 known 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 systems, high or low temperature conditions.
Titanium Slip On Flange
Titanium Slip on flange is a type of titanium flange that 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 strength and no leak. Slip-on flanges can be easily fitted and welded into different pipes. It is perfect for lower-pressure applications.
Titanium Threaded Flange
Titanium-threaded flanges are employed in exceptional circumstances because they can be fastened to a pipeline without welding. These titanium flanges are used in high-pressure systems with small diameter pipes, and the bigger the titanium flange is, the more challenging it is to form a thread. This distinct flange type is more convenient to install and maintain than titanium flat welding and butt-welding flanges and can be used in pipelines that do not permit welding on-site.
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 permits 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.
Titanium Spectacle Flange
A titanium spectacle blind, or a figure-8 blind, is usually a cut-out of metal crafted to fit between two titanium pipe flanges. This item is typically sandwiched between two gaskets and made up of two metal discs connected with a piece of steel. The unique shape of the spectacle blind is said to be reminiscent of a pair of glasses, giving the blind its distinct name.
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 is far from the ring to avoid bending stresses and weld stress being combined.
Titanium Orifice Flange
These flanges are nearly identical to titanium weld neck and slip-on flanges. However, they come with either raised faces or RTJ (Ring Type Joint) facings. They feature additional machining in radial tapped holes for meter connections and orifice plate carriers for fitting the meters. Orifice meters rely on titanium orifice flanges to measure the flow rate of liquids or gases in a pipeline.
Titanium Socket Weld Flange
A titanium socket weld flange has a distinctive inner bore which permits a better stream of fluid accomplished through precise welding and grinding techniques. Developed initially for smaller-sized pipes that necessitate greater pressure, these flanges are known for creating a smoother bore.
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
Titanium flanges 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 are 24" to 60" are available up to 900# class. Pressure-temperature ratings are the maximum allowable working gage pressures in the bar & the temperatures in degrees Celsius. The higher the rating, the 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.

Titanium Flange Has High Strength
The density of titanium alloy is about 4.51g/cm3, which is only 60% of that of steel. The density of pure titanium is close to that of ordinary steel. Some high-strength titanium alloys exceed the strength of many alloy structural steels. Therefore, the specific strength (strength/density) of titanium alloy is much higher than that of other metal structural materials.
Titanium Flange Has High Thermal Strength
Titanium alloy can still maintain the required strength at medium temperature, and can work at 450 ~ 500 ℃ for a long time.
Titanium Flange Has Good Corrosion Resistance

Titanium Flange Has Good Low-Temperature Performance
The mechanical properties of titanium alloy can be maintained at low and ultra-low temperature. Titanium alloys with good low-temperature properties and very low interstitial elements, such as TA7, can maintain a certain plasticity at - 253 ℃. Therefore, titanium alloy is also an important low-temperature structural material.
Titanium Flange Has High Chemical Activity
When the carbon content is more than 0.2%, the hard tic will be formed in the titanium alloy; when the temperature is higher, the hard tin surface will be formed; when the temperature is above 600 ℃, the titanium absorbs oxygen to form a hardened layer with high hardness; when the hydrogen content increases, the brittle layer will also be formed. The depth of hard and brittle surface layer can reach 0.1-0.15mm and the hardening degree is 20% - 30%.
The Thermal Elasticity of Titanium Flange is Small
The thermal conductivity of titanium is 15.24w / (m.k), which is about 1 / 4 of that of nickel, 1 / 5 of that of iron and 1 / 14 of that of aluminum. The elastic modulus of titanium alloy is about 1 / 2 of that of steel, so its rigidity is poor and it is easy to deform.

Process of Manufacturing Titanium Flange
Raw Material
Beginning with this process, the system controls the quality of all external supplies as per the raw material test certificate of the material. Titanium flanges are of premium quality that ensures high durability, strength and resistivity to varied non-supporting conditions.
Material Inspection
Incoming quality control (IQC) is the process of monitoring the quality of materials and parts for manufacturing a product before production starts. With incoming inspection, you can control for quality even before leading a first item inspection or a during production inspection.
Material Cutting
On the central plate, the disk with the internal diameter and the internal diameter of the flange with the processing amount is straight cut out, and the bolt hole and the water line are processed. The flange thus produced is called a cut flange, and the extreme diameter of such a flange is limited to the width of the central plate.
Flange Forging
Forged flanges usually have lower carbon content than cast flanges and are less disposed to rust. Forgings have better streamlined shapes, thicker structure and better mechanical properties. The forged flange is that the inner structure is uniform, and there are no harmful defects such as holes and presence in the casting.
Heat Treatment
The flange is in the process of heat treatment, the overall forging cooling speed is the slowest, the standardizing cooling speed is quicker, reducing cooling speed is faster. Flange are mutually connected and continuous in the process. Coating or packaging methods can protect heating molten salts and in vacuum.
Forging Rolling
Roll forging is a forging method that utilizes opposing rolls to shape a metal part. Even though roll forging uses rolls in order to achieve the deformation of the material, it is classified as a metal forging process and not a rolling process. The forging geometry of the rolls used to forge metal parts is only current over a portion of the roll's edge.
Final Inspection
Place one end of a tape measure on the inside of the flange. The diameter is used to control what size pipe a flange can be used with, so you must find this information by using the inside of the flange as different to the outside. Stretch your tape measure across the center of the circular shape of the flange until it touches the other side of the unit.
Rust Prevention
The standard rust prevention treatment for titanium flanges include yellow (Golden) paint Coating, black paint coating or black phosphating treatment, varnish paint coating, varnish antirust oil coating, electro galvanizing coating (Cold), hot dip galvanizing coating etc.
Well Packing
Titanium flanges must be packed with seaworthy packing method then delivery to customers, usually the packing way include wooden box, wooden pallet, iron & steel cage, iron & steel pallet etc. Because of the normal wooden boxes or wooden pallets have to do fumigation treatment, we usually use plywood pallet or plywood case or box to pack titanium flanges without fumigation treatment.
Calculating the Flanges Weight
While calculating the weight, it is necessary to understand that the construction of pipe flanges is directly connected to the material grade and the pressure it can handle. Just providing a few details like outside diameter and inside diameter, the thickness of the base, the number of drill holes, the diameter of the holes, and the chamfer can easily help calculate the flange weight in seconds.
Measuring Flange Thickness
Flange thickness calculation can be achieved through some techniques. In standard flanges, by understanding the design conditions, especially the pressure and temperature of the piping system and the kind of piping material, the thickness can be found. In this situation, no calculations are required to find the flange dims. Once you find out the flange rating (class), it is easy to find the standard flange dimensions from the ASME B16.5 table.
Flange Specifications
Many standard flange specifications are available depending on the variety of industries. Flange specifications indeed vary according to the industries and their applications. Most of the standard manufacturers offer popular flange specifications like ASME/ANSI flanges, DIN flanges, API flanges, and AWWA flanges. ANSI stands out as the best and most popularly used among the various flange specifications because of its ubiquitous mechanical designs amongst ASME engineers.
