What are the pressure ratings available for an API flange?
The petrochemical sector relies on these flanges conforming to American Petroleum Institute standards. We are a top API 6A flange supplier in UAE, delivering premium products in various sizes. Their applications include refineries, wellheads, and petrochemicals.
Buyers can acquire API 6B flanges from 2000 to 20,000 PSI.
How is an API 605 flange classified based on the face type?
An API 605 flange withstands corrosion and avoids pitting or stress cracking. We can provide raised or flat face, lap joint, ring type joint, and tongue and groove.
We also deliver these flanges in types 6B, 6BX, and segmented, for instance, an API 6A type 6BX 10000 PSI flange.
What is the difference between an API 6A flange and ANSI flanges?
Generally, API 6A type 6B RTJ flanges deliver greater strength and have higher thicknesses. The ratings in ASME and API flanges differ, with the latter supporting higher operating pressures.
Opposed to API 6A 3000 flanges, ASME has pressure classes are from 150 to 2500.

What are the testing and inspection requirements for an API 6A 10000 PSI flange?
The best approach for assessing an API 6A 10000 psi flange is measuring the axial force and the bending moment at the face to gauge the tension. The axial force must be lower than the tension.
An API 10000 flange has bores equal to the nominal flange size. A smaller bore raises the bending moment, leading to more stress. Stress analysis of an API swivel flange is effective at optimising flange capability.
What are the sealing methods used with an API 6A weld neck flange?
Tight and secure sealing is imperative for an API 6A weld neck flange. Conventional sealing methods involve a gasket, for example, a spiral wound gasket. It connects flanges snugly to create a lasting seal.
Different face types are available for sealing an API 6A 5000 flange, such as raised and flat face, O-ring, etc.
Are API 6A 3000 flanges compatible with other flange standards?
An API 6A adapter flange is distinct from ASME components, following a different pressure system and suited to high-pressure applications like oil fields. Even so, a few API and ASME flanges have similar dimensions for bolt circle diameters and can be interchangeable.
We recommend caution while selecting an API 6A blind flange to ensure application compatibility with the application and ambient pressure and temperature.
