For industries where reliability, safety, and precision are non-negotiable, pipe flanges are a fundamental component of any piping system. These essential connectors allow pipes, valves, pumps, and other equipment to be securely joined while also enabling easy disassembly for maintenance or inspection.
At Texas Flange, we have been delivering high-quality domestic and imported flanges since 1986, meeting the needs of industries across the globe. From standard ASME flanges to custom-designed solutions, our mission is to combine top-tier quality, exceptional service, and competitive pricing.
1. What Are Pipe Flanges and Why Are They Important?
A pipe flange is a mechanical device designed to connect two sections of piping or to link pipes with other equipment. These connections can be permanent or removable, depending on the design, and are typically paired with gaskets and bolts to create a tight, leak-proof seal.
Key benefits of flanges include:
Ease of maintenance – Flanges allow system sections to be quickly dismantled for repairs.
Versatility – They are compatible with multiple pipe materials and configurations.
Durability – Properly specified flanges can withstand extreme pressure and temperature conditions.
Industries that rely on flanges include oil and gas, petrochemicals, shipbuilding, water treatment, food processing, and more.
2. Industry Standards and Flange Specifications
At Texas Flange, our products are manufactured in accordance with globally recognized standards, ensuring safety and compatibility for domestic and international projects.
Major standards include:
ASME/ANSI – Common in U.S.-based industries, covering sizes from NPS ½″ to 60″ and pressure classes 150 to 2500.
DIN – Metric standard, widely used across Europe.
API – Specially designed for oilfield applications with high-pressure demands.
JIS – Japanese standard, often used in marine industries
AWWA – Developed for municipal water systems.
3. Domestic vs. Import Flanges
Texas Flange provides both domestic and imported flanges to meet different project needs. Domestic flanges comply with “Made in USA” requirements for federally funded projects, while imported flanges can offer cost advantages for budget-sensitive operations.

4. Common Flange Types
Selecting the right flange type is critical for performance and safety:
Weld Neck – Tapered hub for high-pressure, high-temperature service.
Slip-On – Easy to install, suited for lower-pressure systems.
Blind – Seals off ends of pipelines or vessels.
Socket Weld – Ideal for small-diameter, high-pressure systems.
Threaded – For non-weld connections in low-pressure environments.
Lap Joint – Allows for quick alignment in dismantled systems.
5. Flange Material Options
Material selection depends on the application and environmental conditions:
Carbon Steel – Strength and affordability.
Stainless Steel – Corrosion resistance for harsh or hygienic environments.
Alloy Steel – Enhanced performance for extreme service.
Chrome Steel – Heat and wear resistance.
Special Alloys – For unique chemical compatibility needs.
6. Selecting the Right Flange
When specifying a flange, key factors to consider include:
Operating pressure and temperature range
Material compatibility with the pipeline contents
Industry standard requirements for the project
Maintenance and accessibility needs
A detailed consultation with a trusted supplier like Texas Flange ensures you get the right match for your system.
