Hydraulic “Thrust” Tube Expansion Systems

Product catalog summary

Overview:
The document describes the Powermaster Hydraulic Thrust Expansion System, which utilizes in-line roll tube expanders. It is designed for expanding tubes, particularly in challenging environments such as deep channels and with thick-walled or exotic materials.

Specifications:

Pump Specification: The system requires a power supply of 415v, 3 Phase, and is equipped with a 5 HP electric motor. It has a reservoir capacity of 138 liters (32 gallons) and weighs 450 kg (990 lbs). The height is 1000 mm (39”) over the reservoir and 2630 mm (103”) over the suspension system, with a base dimension of 1220 mm x 630 mm (48” x 25”). The maximum working pressure is 100 bar.
Drive Specification: The system can handle tube ranges from 1/2” to 2” O.D. and up to 5.1/2” thick tube sheets. It operates at a no-load RPM of 780 and uses a control voltage of 24 volts DC. The thrust stroke is 65 mm.

Features:

Designed to expand stainless steel thick-walled and exotic harder tubes where conventional expanders fail.
Capable of expanding tubes in deep channels using a stepping extension.
Ensures a quality leak-proof joint in 3 to 5 seconds with precise control of advancing force.
Maintains constant RPM under load conditions for equal pressure and tight fit.
Durable construction for long, reliable life and reduction of tube stretching and internal stresses.
Simple operation that saves time and reduces operator fatigue.
Includes a large oil tank and external filter for better cooling and easy filter replacement.
Automatic lubrication system to increase tool life and reduce consumable costs.
Features a continuous programmed cycle controlled by a microprocessor.

Additional Information:
Optional stepping space is available for rolling thicker tube sheets without removing the expander from the tube. Extensions for expanding tubes in deep channels are also available. The system is supplied with an operation manual detailing features and accessories.
