API 6A Type 6BX and API 6A Type 6B flanges are both designed to meet API 6A standards and are intended for use in high-pressure environments, but they serve slightly different purposes. API 6B flanges are ring-type joint (RTJ) flanges with a maximum pressure rating of 3,000 PSI that are widely used in the oil and gas industry. They enable easy inspection of welds and reduce flow turbulence. API 6BX flanges are RTJ flanges that handle much higher pressures, with a minimum yield strength of 75,000 PSI. Tesco Steel & Engineering is a leading API 6A Type 6BX Flanges manufacturer. We provide in sizes from ½ inch to 24 inches in premium materials such as carbon steel, stainless steel, duplex, inconel, and hastelloy. All 6BX flanges are heat-treated and tested to meet PSL 1 and PSL 2 standards.
The main difference between API 6B and API 6BX flanges is pressure handling. While both are ring joint types, 6B flanges suit lower pressure conditions. API 6BX flanges are made for much higher pressure ratings and are not interchangeable with 6B types. They also require different bolting patterns and gasket compatibility, which makes it important to select the correct type for your application.
These flanges perform well under tough conditions. API 6A Type 6B 3000 PSI flanges provide reliable strength, smooth flow, and simple weld checks. They reduce stress on pipelines, which helps extend service life. API 6BX flanges offer even greater durability for extreme pressure zones. Both types are trusted in sectors like petroleum, petrochemical, offshore platforms, and natural gas processing.
As a trusted API 6A Type 6BX Flanges supplier, we provide custom products that meet needs of demanding environments.
