Non-ferrous titanium or titanium alloy helps craft a Titanium flanges. A pipe-connecting part attaches to the pipe end and is replete with a series of holes for secure attachment through bolts. Gaskets are positioned between the two titanium flanges for proper sealing.

The titanium flanges are combined with lugs or adapters. Each is either cast, threaded, or welded alongside a gasket and several bolts and nuts. After fastening the nuts, a specified pressure deforms the gasket and fills any imperfections on the seal to create a tight bond, maximizing the flange&#;s weight capacity.

Different Types of titanium flanges &#; An Overview 

• Titanium Weld Neck flange

Titanium weld neck flanges have a distinct advantage over other types, with their tapered hub and seamless transition from flange thickness to pipe wall thickness. This design ensures excellent deformation resistance and makes them the perfect choice for systems exposed to high pressure, temperature changes, and hazardous substances. The downside to titanium weld neck flanges is their large size, complex assembly, and cost. Furthermore, they are susceptible to damage during transport.

• Titanium Slip On flange

The Titanium Slip On Flange is a flange that fits over the end of a steel pipe and is welded in place as it slides onto the pipe. This process creates a low hub that can be welded from the inside and outside, granting the flange great strength with no leaks. Slip-on Flanges can be attached easily to various types of piping and are optimal for applications involving lower pressure.

What are flange dims for slip-on types?

Slip-On Flanges come in a range of sizes and pressure classes, with standard outer diameters of 1/2&#;, 2&#;, 3&#;, 4&#;, 6&#;, 8&#;, 10&#;, 12&#; up to 24&#; and special sizes up to 60&#;. Their pressure classes range from 2.5 PN to 250 PN, covering classes from 150 to (# or LB).

The major benefits of this flange are the convenience for welding or processing as it can be used with materials like plastic and glass steel pipes, and also in terms of construction as the flange bolt hole can be easily aligned and helps prevent any replacement needs for the titanium equipment flange. It can help reduce expenses when a high price is in place, as the titanium flange with the same material can be expensive.

• 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

Made of titanium, the blind flange is an often-used pipe flange distinguished by its lack of a bore in the center. Primarily utilized to cap off pipelines, this flange allows easy access to the line once sealed. With the ability to be machined, it is possible to fit a standard-sized pipe to which a threaded or welded downsize is connected.

• 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

The Titanium Integral Flange, or Titanium Long Weld Neck Flange (LWN Flange), is a high-pressure application solution. This flange features an integral hub with a weld neck far from the ring to minimize bending and welding stress concentration risk.

• 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

Constructing junctions, tees, and joints is made possible through a titanium plate flange, a flat circular disk welded to the end of a steel pipe. When two titanium flanges are joined, they are secured with a gasket and bolts through the surrounding holes. Typically used for water and fuel pipelines, these plates are invaluable.

• Titanium Non-Standard flange

• Titanium flange Pressure-Temperature Class (Service Rating)

Titanium flanges are rated by their pressure-temperature characteristics, categorized as 150#, 300#, 400#, 600#, 900#, #, and #. Flanges of 24&#; to 60&#; diameter can support a 900# rating. This translates to the maximum operating pressure of the bar and temperature of degrees Celsius.

A heavier flange allows for a higher pressure-temperature rating, with an inverse relationship between temperature and pressure. Note that different materials have different pressure tolerances.

• Titanium Flange Facing Types

Titanium flange facing has five distinct types: flat face, raised face, ring joint, tongue and groove, and male and female.

Material Used in Titanium Flanges

ASTM International standard on titanium and titanium alloy seamless pipe includes alloys such as Grades 5, 23, 24, 25, 29, 35, and 36, which can be supplied as annealed or aged, cold-worked and stress-relieved or annealed, transformed-beta condition, and solution-treated or solution-treated and aged, respectively.

The unalloyed grades, ranging from 1 to 4, are classified as commercially pure or &#;CP.&#; These grades usually feature higher tensile and yield strength with the increase in grade numbers, the difference in their physical properties mainly results from the interstitial elements, which makes them applicable in corrosion-resistance tasks.

Grade 5, often referred to as Ti6Al4V, Ti-6Al-4V, or Ti 6-4, has 5% aluminum and 2.5% tin, making it ideal for aircraft and jet engines because of its superior weldability, strength, and stability under high temperatures.
