Technical Data Overview for Seamless Concentric and Eccentric Reducers (ASME B16.9)

This document provides detailed technical specifications for carbon steel seamless concentric and eccentric reducers compliant with ASME B16.9 standards. The data includes dimensions, thicknesses, schedules, and theoretical weights for various reducer sizes.

1. Dimensional Specifications

• Nominal Sizes: Reducers are specified by two nominal diameters in inches (e.g., 1" x 3/4", 12" x 6", 24" x 20").
• Outside Diameters (D.E.): Provided in millimeters for both ends of the reducer, corresponding to the nominal sizes.
• Thickness (Spess./Thickn): Wall thicknesses are given in millimeters for each end, with two thickness categories: Standard (Std) and Extra Strong (Xs).
• Schedules (SCH H): Pipe schedule numbers are listed, indicating wall thickness standards.

2. Weight Information

• Theoretical Weight: Theoretical weights in kilograms are provided for each reducer size and thickness category, facilitating material estimation and handling considerations.

3. Thickness Categories

• Standard (Std): Typical wall thickness for general applications.
• Extra Strong (Xs): Increased wall thickness for higher pressure or mechanical requirements.

4. Notes and Disclaimers

• The technical data are indicative and not binding, meaning actual product specifications may vary.
• Data date of issue: 2014, Revision 01.

5. Summary of Key Parameters

Nominal Size (inches)	Outside Diameter (mm)	Thickness (mm) Std / Xs	Schedule (SCH H)	Theoretical Weight (Kg) Std / Xs
1" x 3/4"	33.40 x 26.70	3.38 x 2.87 / 4.55 x 3.91	51	0.14 / 0.17
12" x 6"	323.90 x 168.30	9.53 x 7.11 / 12.70 x 10.97	203	14.10 / 18.40
24" x 20"	609.60 x 508.00	9.53 x 9.53 / 12.70 x 12.70	75.80	Not specified / 99.90

6. Application and Usage

These reducers are used in piping systems to connect pipes of different diameters while maintaining pressure integrity. The availability of standard and extra strong thicknesses allows selection based on pressure and mechanical requirements.

7. Manufacturing and Compliance

The reducers are seamless and manufactured according to ASME B16.9 standards, ensuring quality and compatibility with industrial piping systems.

8. Important Considerations

• Users should verify actual product specifications before use due to the indicative nature of the data.
• Weight and thickness values are critical for design calculations and material handling.

Note: The document contains extensive tabulated data for a wide range of reducer sizes and thicknesses, which should be consulted directly for detailed engineering design.
