Custom Flanges

Does Texas Flange do Custom Flanges?

We get many calls asking for large blind flanges accompanied by the question, “can you bore that out to X for me?”.  What many engineers, estimators, and purchasing agents might not realize is how easy it is to get a custom flange from Texas Flange.

For a custom ring flange, all we need is the OD, ID, thickness, bolt pattern, and grade of material. Get us that information, and we can quote for as few as ONE piece – yes, there’s no minimum quantity even on customs (though large quantities will of course receive discounts due to set up costs being distributed more widely).

Here’s a base flange template which many of our customers have used for reference/guidance. Call us or shoot us an email to discuss your flange application, and we will send you the right template for you to use:

We also provide custom flange templates for you to modify to your liking to get a better understanding of your application.

Additionally, drawings for approval can be requested prior to actual manufacturing, provided an order already stands.

This gives you an opportunity to have one final review of your incoming product before we throw your forging onto the machines.

Anyone can provide standard commodity B16.5 flanges, but not everyone can make them in small quantities with a quick turn-around when something needs to be modified past typical industry requirements.

That’s where Texas Flange comes in. Non-stock material grades, custom faces, or threaded bolt holes? We like to say that specials are our specialty! We are here to help you hit those project deadlines.

Although we do not directly design custom flanges, we do provide custom flanges to your requirements. We do not always have a standard for reference if your job isn’t to ASME code, and so we have to confirm all the dimensions with you.

When you order a custom flange, please show all the details or requirements to our sales staff to ensure our quotation will be accurate.

Frequently Asked Questions (FAQs)

A duplex flange is a pipe flange made from duplex stainless steel, which consists of a balanced microstructure of austenite and ferrite. This composition provides high strength, excellent corrosion resistance, and durability, making it suitable for industries such as oil and gas, chemical processing, and marine applications.
The three main types of flanges are weld neck, slip-on, and blind flanges. A weld neck flange has a long tapered hub that is welded to the pipe, providing high strength and reducing stress concentration. A slip-on flange slides over the pipe and is welded in place, offering easy installation but lower strength compared to a weld neck flange. A blind flange is a solid flange used to close the end of a pipeline, preventing flow.

FF (Flat Face) and RF (Raised Face) flanges refer to the type of sealing surface on the flange. An FF flange has a flat surface across the entire face, making it suitable for applications where gasket seating must be fully flush.

These are often used in low-pressure applications. An RF flange has a raised surface around the bore, which helps concentrate gasket compression for a better seal, making it more common in high-pressure and high-temperature applications.

Flanges are specified based on several factors, including their nominal pipe size (NPS), pressure class (e.g., 150, 300, 600, etc.), face type (FF, RF, or RTJ), material (such as carbon steel, stainless steel, or duplex steel), and standard compliance (such as ASME B16.5 or EN 1092-1).
Flanges are manufactured by specialized companies worldwide, including major industrial suppliers and manufacturers such as Weldbend, Texas Flange, Metline Industries, and Viraj Profiles. These companies produce flanges that comply with international standards and serve industries like oil and gas, petrochemicals, power generation, and construction.
