1200-5 SERIES

Product catalog summary

Specifications:
The document provides specifications for tube expanders suitable for tubes with internal diameters ranging from 14.8 mm (0.584 inches) to 36.3 mm (1.43 inches). The tube expanders are fitted with adjustable roller lengths, with minimum and maximum lengths specified as follows: 38.1 mm (1.1/2 inches) to 57.1 mm (2.1/4 inches) for standard reach, and up to 304.6 mm (12 inches) for maximum reach.

Procedures and Recommendations:
For optimal results, a 'Thin Wall Thrust Collar' is recommended when rolling tubes with wall thicknesses between 19 and 22 gauge. This is particularly advised for thin-walled tubes made of materials like Titanium and Incoloy in thick tube sheets. The use of these collars helps achieve a more concentric and even expansion, reducing the tube spring back effect.

Tool Specifications:
The document lists various models of expanders, such as Model 1223-5 to 1300-5, which come with different mandrel drive sizes (3/8 inch and 1/2 inch square). These expanders are highly recommended for use on thin-walled tubes of exotic materials.

Advantages:
The five-roll expander design provides a more even expansion compared to conventional three-roll expanders, especially beneficial for thin-walled tubes.

Data Summary:
The document includes detailed tables listing tube outer diameters, thicknesses, and corresponding expander models. It specifies the minimum internal diameter the tool can enter and the maximum expansion capability. The tables also provide complete tool numbers, mandrel numbers, and roller set numbers for different tube sizes.

Catalog excerpts

TUBE EXPANDERS FITTED WITH ROLLER LENGTH • Use : Highly recommended for use on thin walled tubes (19 thru 22 gage walls) of Stainless Steel, Titanium, Incoloy and other exotic materials in thick tube sheets. • Advantages : Gives a more concentric and even expansion when expanding thin walled tubes vs. a conventional 3 roll expander and reduces tube spring back effect. • Expanders for tube sizes not listed below are also available. Please enquire. For best results a ‘Thin Wall Thrust Collar’ should be used when rolling 19 thru 22 gauge wall tubes. (See Pg. 5) Model 1223-5 - 1258-5 expanders come with 3/8” square mandrel drives and Model 1263-5 - 1300-5 expanders come with 1/2” square mandrel drives.
