What is an E flange?



An "E flange" typically refers to a type of flange used in piping systems, particularly in accordance with API 6A (American Petroleum Institute Standard 6A) for pipelines in the oil and gas industry. The "E" in E flange stands for "expansion," which indicates that this type of flange is designed to accommodate expansion and contraction due to temperature changes without causing leaks.

E flanges are usually steel components with a raised face and are often used in conjunction with blind flanges, which are flat plates with holes that line up with the pipeline to create a seal. The E flange features a tongue and groove design on the mating faces, which allows for movement in three directions to compensate for thermal expansion and contraction.

These flanges are known for their robustness and are commonly used in high-pressure and high-temperature applications. The API 6A specification covers the requirements for designing, manufacturing, and testing steel flanges intended for use in pipeline systems carrying fluids and other materials.
