titanium flange:1/2"-48"

Product Description

Titanium welding neck flanges are used in pipe systems made of titanium to provide strong and leakproof connections between pipes. Their design features include long tapered necks that act like extensions of their respective pipe; as well as an easily weldable faceplate to allow welding with other piping pieces.

Here are a few key benefits and features of titanium welding neck flanges:

Material: Titanium welding neck flanges are constructed using titanium, an exceptionally corrosion-resistant metal with exceptional corrosion resistance, high strength-to-weight ratio and excellent heat resistance properties that makes it suitable for various industries including chemical processing, oil & gas and marine applications.

Leakproof Connection: The welding neck design offers a smooth transition from pipe to flange, eliminating leakage or weak spots within the joint and helping ensure leak-free connections.

Titanium welding neck flanges offer superior tensile strength while being lighter compared to other metals, making them the ideal choice when weight reduction is paramount without compromising strength.

Titanium's versatility means it is compatible with an extensive array of corrosive fluids such as seawater, acids and chemicals - making titanium welding neck flanges well suited for use in highly acidic environments.

Temperature Resistance: Titanium has proven its ability to withstand elevated temperatures without degrade or lose strength, making it the perfect material choice for applications involving higher heat loads.

Titanium's corrosion resistance and durability contributes to their long lifespan as welding neck flanges, eliminating frequent repairs or replacement.

According to ASME B16.5, the standard dimensions for titanium welding neck flanges (also known as WN flanges) are as follows:

Nominal Pipe Size (NPS): 1/2" to 24"
Flange Class Ratings: 150, 300, 400, 600, 900, 1500, and 2500
Flange Facings: Raised Face (RF), Flat Face (FF), Ring Type Joint (RTJ)
Flange Materials: Titanium (grade 1, 2, 5, 7, 12), with the grade specified based on the application requirements

The dimensions for titanium welding neck flanges, such as outside diameter (OD), bolt circle diameter (BCD), neck diameter (ND), and thickness (T), vary depending on the nominal pipe size and the flange class rating.

Manufacturing titanium welding neck flanges usually involves three main steps. These include:
Prep Step: Acquire high-grade titanium material (typically bars or plates), clean or treat its surfaces to remove impurities, and perform any required surface treatments in order to clean off impurities from it. Flange Design: Determine required dimensions, welding neck length, class rating and facing type (RF, FF or RTJ) depending upon application requirements and ASME B16.5 standards. Cutting and Shaping: Use cutting techniques such as sawing or shearing to transform titanium material into the ideal shape and size for the flange, such as drilling out an opening for pipe passage and creating the neck of the flange. Turning and Machining: Incorporating turning and machining processes can help refine dimensions, smooth surfaces and meet precise tolerances more precisely than other means can. These operations might include facing, chamfering, drilling bolt holes or beveling welding ends - among many others. Heat Treatment: When necessary, subject the titanium flange to heat treatment processes such as annealing or stress relieving to enhance its mechanical properties and alleviate residual stresses.
