ASME B16.9 ECC RED. ASTM A234 GRAU WP11 CL 2 12" X 8" SCH 20 X 20

ASME B16.9 ECC RED. ASTM A234 GRADE WP11 CL 2 12" x 8" SCH 20 X 20" specifies a particular type of pipe fitting, an eccentric reducer. Here's what each component of the designation means:

ASME B16.9 ECC RED.: This indicates that the fitting is an eccentric reducer manufactured according to the ASME B16.9 standard. An eccentric reducer is a type of pipe fitting used to connect pipes of different sizes but with the centerlines of the pipes at different heights, creating a smooth transition for fluid flow while minimizing turbulence.

ASTM A234 GRADE WP11 CL 2: This refers to the material grade of the fitting. ASTM A234 is the specification for pipe fittings of wrought carbon steel and alloy steel for moderate and high-temperature service. GRADE WP11 CL 2 specifically denotes the grade WP11, which is a type of chromium-molybdenum alloy steel, and CL 2 indicates that it meets specific supplementary requirements according to the ASTM standard.

12" x 8": This indicates the sizes of the pipes being connected by the eccentric reducer. In this case, it specifies a reducer transitioning from a 12-inch pipe to an 8-inch pipe.

SCH 20 X 20: This indicates the schedule or thickness of the pipe wall for both the 12-inch and 8-inch pipes. In this case, both pipes have a schedule 20 thickness.

ASME B16.9 ECC RED. ASTM A234 GRADE WP11 CL 2 12" x 8" SCH 20 X 20" specifies an eccentric reducer pipe fitting made of ASTM A234 Grade WP11 alloy steel, meeting Class 2 requirements, transitioning from a 12-inch pipe to an 8-inch pipe, with both pipes having a schedule 20 thickness.
