Elbow

A steel elbow is a type of pipe fitting used in plumbing and piping systems to change the direction of the flow of fluids (liquids or gases). It is a curved piece of steel pipe that allows for a smooth change in direction, typically at a 90-degree or 45-degree angle.

These specifications provide a standardized way to classify and specify the characteristics of steel materials used for manufacturing pipe fittings. The selection of a particular grade depends on factors such as the intended application, service conditions, and required mechanical properties. Engineers and designers refer to these specifications to ensure the appropriate material is used for specific piping system requirements.
