ASME Flanges

Steel flange dimensions are determined by the pipe size and the pressure class required for the application.
Flanges are standardized according to publications from organizations like ASME, ANSI, MSS, API, and others.
We supply high-quality ANSI/ASME flanges manufactured in accordance with ANSI/ASME B16.5 and B16.47 standards, suitable for a wide range of industrial applications, including oil and gas, petrochemical, power generation, water treatment, and general piping systems.
Our steel flange range includes various types such as blind flanges, weld neck flanges, lap joint flanges, and slip on flanges, designed to ensure secure and leak-proof connections in piping systems. These flanges are available in multiple pressure ratings, including Class 150, 300, 600, 900, and higher, to meet different system requirements.

The dimensions of our steel flanges are precisely engineered, dictated by the specific pipe size and the pressure class required for your application. We adhere strictly to the globally recognized standards set by organizations like ASME, ANSI, and API, ensuring every flange we supply is a testament to quality and reliability.

Our comprehensive inventory includes a wide variety of flange types to suit every connection need:

ASME Blind Flanges: Ideal for sealing off the end of a piping system.
ASME Weld Neck Flanges: Designed for high-pressure and high-temperature applications, offering superior strength and integrity.
ASME Lap Joint Flanges: Perfect for systems requiring frequent dismantling or alignment adjustments.
ASME Slip-On Flanges: A cost-effective solution for lower-pressure applications, offering easy installation.
These forged steel flanges are available across a spectrum of pressure ratings, including Class 150, 300, 600, 900, and even higher, to seamlessly integrate with your system’s unique operational demands.

Superior Materials for Lasting Performance

We believe that exceptional flanges begin with exceptional materials. Our ASME steel flanges are crafted from premium-grade materials, ensuring unparalleled durability, corrosion resistance, and reliable performance in even the most challenging environments.
