Incorrect flange selection can risk joint failure and cause operational delays. We manufacture these flanges using forged carbon steel, stainless steel, or duplex alloys, with RTJ faces for controlled metal-to-metal sealing.
API 6A Flanges must resist high-pressure cycling, sour fluid exposure, and temperature shifts. We supply flanges in through-bore sizes from 1-13/16″ to 21-1/4″, CNC machined to meet API 6A Table 5 specifications.
These flanges maintain a surface finish of 63-125 μin RA in sealing grooves for RX/BX compatibility. Bolt circle and stud sizing match API 6A Table 5.3, with stud grades as per ASTM A193 B7 or B16.

Connects casing and tubing heads with ring joint sealing to handle high axial and pressure loads.
Joins flowline outputs through 6BX flanges, maintaining structural integrity during continuous multiphase fluid transfer in surface production facilities.
Integrates 20000 psi flanges for high-pressure pumping applications, with material compliance to NACE MR0175.
Enables flow routing through studded flanges and BX gasket faces, minimizing leak points in critical areas.
Uses 6B and blind flanges for safe shutoff, supporting full traceability and PSL4 requirements.
Interfaces with ring joint flanges for repeatable sealing under cyclic load conditions.
Your upstream operations depend on flange joints that offer safety and compliance without delays. We control each stage of forging, machining, and coating in-house, ensuring conformance to API Q1 and full traceability.
With no slip-on or socket weld options, we limit your risk of improper installation in pressure-rated applications. These flanges fit into your systems with standard RTJ gaskets, reducing gasket mix-ups during assembly.
Check all our Frequently Asked Question
No, API 6A flanges do not align with ASME B16.5 bolt patterns or gasket styles. They are built for high-pressure oilfield use and follow completely different dimensional charts. Mixing both types risks leakage or joint failure.
Yes, every flange includes heat number mapping, MTRs, and inspection stamps as per API Q1 guidelines. We record all production stages from forging to final CNC machining. This traceability supports PSL2 and higher procurement requirements.
We do not supply gaskets by default with flange orders. However, we support sourcing guidance for API 6A BX-type ring gaskets. Each flange is machined to suit only the matching BX profile with no substitutes.
We conduct dimensional inspection, RTJ surface roughness checks, and hydrostatic pressure tests based on PSL level. Test certificates and visual records are shared with every lot. These checks meet API 6A 21st Edition criteria.
Choose 6B for lower pressures up to 5000 psi and 6BX for compact high-pressure designs up to 20000 psi. 6BX needs BX gaskets and supports metal-to-metal sealing under ring groove tension. Selection depends on your working pressure and field installation layout.
