Tube Sheet and Tube Specifications

This section provides detailed specifications for tube sheets and tubes, including tube sheet thickness, tube projection, over roll, and tube outer diameter (O.D.). The data is organized by tube sizes ranging from 1 inch to 4.5 inches and corresponding thicknesses in both inches and millimeters. Key parameters include tube thickness (bwg), minimum inner diameter (I.D.), and tube projection over roll dimensions.

Key Parameters:

• Tube Sheet Thickness: Ranges from 1 inch to over 4 inches, with specific thickness values provided for each tube size.
• Tube Projection Over Roll: Values vary depending on tube size and thickness, critical for proper tube expansion and fitting.
• Tube Outer Diameter (O.D.): Provided in inches and millimeters, essential for selecting appropriate tools and ensuring compatibility.

PowerMaster P-3000 Series Tube Expanders with Collar

This section describes the P-3000 Series tube expanders equipped with collars, designed for precise positioning within boiler tubes relative to the drum for consistent expansions.

Usage and Features:

• Intended for boiler tube sheets and drums thicker than 2.75 inches (70 mm).
• Typically used alongside the P-1000 Series for enhanced performance.
• Allows accurate positioning of the expander tool to ensure uniform tube expansion.

Technical Details:

• Tube Sheet Thickness Range: Covers tubes from 0.5 inch to 4.375 inches and tube sheet thicknesses from 1.5 inches to 5.375 inches.
• Mandrel and Roller Model Numbers: A comprehensive list of mandrel and roller sets is provided, each corresponding to specific tube sizes and thicknesses, ensuring correct tool selection.
• Mandrel Square Drive Size: Specified for compatibility with different drum types and tool configurations.

Summary of Critical Information

• Precise tube and tube sheet dimensions are essential for selecting the correct tube expander model and ensuring proper tube expansion.
• The P-3000 Series with collar is specialized for thicker tube sheets and provides consistent, accurate expansion.
• Tool model numbers and specifications are matched to tube sizes and thicknesses to optimize performance and reliability.

This document serves as a technical reference for engineers and technicians involved in boiler tube maintenance and expansion, providing essential data for tool selection and operational procedures.
