Carbon Steel / Stainless / Alloy Flanges per ASME / ANSI / AWWA / API
Manufacturing and supplying a complete line of industrial pipe flanges with multiple materials available.
What We Supply
From standard ASME pressure classes to custom specialty flanges - we stock and supply what your project needs.
High-pressure and high-temperature systems. Butt-weld connection distributes stress across the joint. ASME B16.5 compliant.
Economical choice for lower pressure applications. Easy alignment and installation in water, utility, and HVAC systems.
Solid disc flanges to close off pipe ends or Vessel openings. Handles substantial bolt stress for pressure testing.
Single external fillet weld for small-diameter, high-pressure systems. Ideal for non-corrosive fluid service.
Used with stub ends for cost-effective connections. Full rotation for easy bolt-hole alignment during assembly.
No-weld connection for low-pressure services and areas where welding is restricted. Fast field installation.
Standards We Work To
Available in all standard pressure classes: 150, 300, 600, 900, 1500, and 2500.
"Alloy" is a bit of a blanket term we use to describe material grades that don't fall neatly into the carbon or stainless steel categories. Most nickel alloys land here: think Hastelloy, Inconel, Incoloy, and Monel, along with other commercially available materials we carry like aluminum, titanium, copper, and bronze. Texas Flange stocks a wide range of alloy flanges and fittings made to industry standard specifications. For high nickel alloys specifically, ASTM B564 is the primary spec to know.
These materials shine in applications where corrosion resistance or temperature extremes are a concern: corrosive processing environments, refineries, pressure vessel work, and similar demanding service conditions. Read our blogs for a closer look at some of the most commonly specified alloys and what makes each one a good fit for certain applications.
High yield carbon steel is essentially a heat-treated version of standard carbon steel - processed to significantly raise its yield strength, which is the point at which the metal starts to permanently deform under stress. The governing specifications are A694 and MSS-SP44, which cover grades F42 through F70.
These piping flanges mate and weld to high yield pipe grades X42 through X70. You'll typically see these flanges specified in higher-pressure, higher-temperature applications, usually Class 600 and above - situations where mild carbon steel just isn't rated for the job requirements.
Since 1986
We manufacture and supply a complete line of industrial pipe flanges - carbon steel, stainless steel, and alloy - to meet the demands of oil and gas, petrochemical, power generation, and water treatment industries.
Every flange ships with full traceability. Mill Test Reports and third-party certifications available on request for domestic and import materials.
Custom flanges? Specialty items like orifice flanges, spectacle blinds, and long weldnecks? We handle those too.
