Substantial Savings Realized With

HydroSwage MK III Tube Expander —Literature Available—

Torque & Tension Equipment,

Inc., of Santa Clara, Calif., recently announced a dramatic improvement and cost savings for expanding the

Vi-inch, 3/s-inch, and 5/s-inch tubes for coolers, condensers, and heat ex- changers on surface ships by using the MKIII HydroSwage Tube Ex- pander from Haskel, Inc. Utilizing precisely controlled uniform hy- draulic water pressure between two seals, this method is safe, fast, and economical. The MKIII Hydro-

Swage Tube Expander, which re- cently was approved for use by

NAVSEA for both new and retubing applications, can dramatically cut tooling costs associated with tube rollers for these applications.

The MKIII HydroSwage Tube

Expander, with digital pressure readout and control capabilities, is

Mart III

HYDROSWAGE* the result of 16 years' experience with hydraulic expansion tech- niques for expanding tubes into a tubesheet by applying uniform con- trolled water pressure in the tube ends. The pressure, or expansion force, is accurately set, measured, repeated, and controlled. This pro- duces a better job in addition to being more cost effective.

HydroSwage tube expanding nor- mally takes place in two quick steps.

First, the tubes are locked or set into their axial position. Secondly, in a matter of seconds, high pressure water is applied in the tube ends resulting in a leak-tight expansion.

When doing the job right the first time at substantial savings is a valid concern, the manufacturer states, the alternative to tube rolling is the

Haskel MKIII HydroSwage Tube

Expander.

Slingmax Rigging Products

Offers Literature On New

Load-Lifting Equipment

Slingmax Rigging Products, As- ton, Pa., has added Twin-Path Ex- tra™ Slings to their product line, according to Dennis St. Germain, president of the company. The com- pany already markets the innova- tive Twin-Path™ Lifting Sling line.

The new sling product consists of two complete slings in one, each making separate connections be- tween hook and load, with double- layered covers for extra protection.

This back-up system helps m„ din control of the load should damage occur. The double-layered, color- coded covers make for easy inspec- tion.

The shape of the Twin-Path Ex- tra Sling easily adapts to fit both hooks and shackles that might be too small for other slings and gives the widest possible bearing contact with the load. Beside their flexibili- ty, the slings are extremely light and strong.

Slingmax Twin-Path Extra Lift- ing Slings are represented in Cana- da by Strider-Resource, with agree- ments pending in Europe and Asia.
