In piping material, "SB" typically stands for "Specification Boiler," which refers to a standard developed by the American Society for Testing and Materials (ASTM) for various types of piping and fittings. This designation is often seen in conjunction with specific material standards, such as ASTM SB-16, which pertains to seamless wrought steel pipe. It indicates that the material meets certain quality and performance criteria for use in pressure applications.
