API 6BX Ring Type Joint Flange
API 6BX ring type joint flange with metal ring-gasket sealing — A105 and LF2 materials, sizes 2 in to 24 in, for high-pressure systems.

API Standard Flanges · Sourced on Order
High-pressure weld neck flanges sourced to API 6A for wellheads, flowlines and pressure-control equipment. The long tapered hub gives a smooth stress transition into the pipe wall, which is why these flanges are the first choice where lines are welded, pigged and pressure-tested. We source them in carbon steel A105, low-temperature LF2 and high-strength F52 grades, with RF, RTJ, 6B and 6BX facings and material test certificates available on request. Send us your size, pressure class and facing requirement and we will quote the exact flange for your line.
