The Tridan Flexpander – For semi-portable coil expansion

The Tridan Flexpander - For semi-portable coil expansion

At Tridan International, we developed a unique coil expansion machine known as the Flexpander. The Tridan Flexpander comes in the FE and FE-5 models.  What a Flexpander does is expands mechanical tubes for heat transfer coils. It is unique designs and machines like these that sets Tridan International apart from other companies. By leading the industry in design and innovation, Tridan provides the best solutions for coil manufactures.

Tridan Flexpander Benefits

One of the advantages of our Flaxpander machines is the semi-portable design. YOu can move the machine to where you need it in the shop. The Flexpander – FE can expand two tubes per cycle and handle any work load. The balanced FE allows for you to rotate it to what angle you need it allowing for diagonal, horizontal or vertical expanding. While the FE and the FE-5 both can handle good volumes of work, the Quadpander is ideal for large volume of work.

The Quadpander QE was created for larger commercial or industrial producers. In addition, the QE can handle almost three times that of the FE or FE-5. Also, this helps provide manufacturers with lower cost and more efficiency in producing coils. Another great benefit of the QE is no limitations on the coil length being expanded. In addition, you will have excellent control of the coil dimensions.

While the Quadpander is a great machine, we do offer other coil expansion machines as well. The Super Flexpander – SFE and the Super Flexpander – SFE-4W are also available. The SFE is designed for specialized needs. This Flexpander is designed to expand large diameter coils, unique materials, and thicker wall coils. Both of these Super Flexpanders are currently available at Tridan International.

Finally, we strive to provide the best machinery for the industry. Our innovative machines and reliability set us apart from the other companies. Give us a call today at 217-443-3592 or fill out one of quote forms for a quote on Tridan machines today!

Lubricants For The Coil Manufacturing Industry

Lubricants For The Coil Manufacturing Industry

Tridan International offers a complete line of lubricants for the coil manufacturing industry. Our lubricants are created to provide optimum performance for coil manufacturing machines and other equipment. We carry fin stock lube, hydraulic oils, tubing lube, and miscellaneous lube.  In addition, we pride ourselves in quality and we have a quality management program that guarantees the best product possible.

Coil Manufacturing Industry Oil and Lube

The quality management program analyzes the statistical process and controls both the incoming raw materials and outgoing finished product. Also, our quality control program tests include tests for:

  • X-Ray Fluorescent Analysis
  •  Infrared Analysis
  • Viscosity
  • API Gravity
  • Flash Point
  • Pour Point
  • Floc Point Falex Lubrication
  • Moisture
  • Ph
  • Acid Number
  • Base Number

Tridan’s lubricants are thoroughly tested to perform for forming and tool life properties. In addition, the lubricants are compatible with the old and new generation of refrigerants. Mineral or Petroleum-based lubricants need to be removed from the coil either by vapor degreasing or through the use of aqueous cleaner. With these type of lubricants create a superior fin collar drawing capabilities in addition to the best possible protection for an extended tooling life.

Lubricants in general, do not require cleaning. These types of lubricants are known as evaporative. This means that most of the lubricant will evaporate from the fin’s surface. Also, there are some lubricants that are used for tube bending and expansion, that will not evaporate and stay on the tubing. Of course, Tridan lubricants are compatible with refrigerant oils. We also offer TriLub HYD-AW series hydraulic oils that are available in ISO 32, 46, and 68 grade.

This just covers some of the great lubricants and oil we have available at Tridan. Call us today at 217-443-3592 to learn more about all our available lubricants and oils. Finally, contact us now and see all the advantages Tridan can provide for your business.

Tube Expanding Machines For Texas and Oklahoma

Tube expanding is the process of reducing a tube wall. By simply expanding the diameter of a tube, you avoid having to purchase all new tubing. Tube expansion has been an important process for a multitude of industries.

Steps of Tube Expanding

There are a few steps one should take prior to tube expanding process. These steps are as follow:

  1. Be sure to know the hole size and the outside diameter of the tube
  2. Subtract the outside diameter from the hole dimensionCoil Expanding
  3. Determine the inside diameter of the tube
  4. Add the inside diameter to the clearance between the outside diameter

Tube Expansion Machinery

As many of you already know, there are a variety of tube expansion machinery within the industry. At Tridan International, we have an extensive line of tube expansion machinery that are available in different forms. Also, these options include horizontal expansion, vertical expansion, and semi-portable expanders.

Different Types of Tube Expanding Machinery

Serving in the Texas and Oklahoma area, we offer coil expansion solutions from small coil to large coil.

Horizontal Tube Expansion

This type of machinery can expand and add the final belling to a tube at the same time. The horizontal tube expansion uses no hydraulics and over time, it has changed its coil sizes very little.

Vertical Tube Expansion

The vertical tube expansion machines are created with saving space in mind. These double sided machines are capable of doing two different jobs at one time to cut down on time. Believe it or not, because of this process, it’s able to save up to 22% in head room.

Semi-Portable Expanders

Semi-portable expanders are versatile portable systems that are designed to be much more mobile than the larger counterparts. In addition, this kind of machinery is able to produce a large amount of volume and are ideal for smaller shops.

Tube Expansion at Tridan International

Coil Expanders

Tube ExpanderAt Tridan International, we have a wide array of coil expansion machines that can handle your needs. Of course those not familiar with coil expanders, they are devices or machines used to increase the diameter of types tubing. The expander is made up of several sections that are then added to a threaded shaft. Then the device is inserted into the tube, and the expander is then tightened. This will force the device to push outwards and then results in the expansion of the tube.

Our Coil expanders become more beneficial with end sizing of tubes.  They can easily be shaped as bell and flare or just bell to custom specifications and fully ready for bend insertion. Many industries use the products that are made using our tube expansion machinery.  HVAC system and heat exchanger manufacturers for example; use them for building products. Those in turn, are used in many factories and industrial complexes world wide.

Horizontal or Vertical Expander Machines

Tridan International is one of the nation’s leading manufacturer of tube expanding machines. With our extensive line of coil and tube expanding machines, we have machines that can accomodate any size business. Horizontal and Vertical, from high volume to low volume, we have it. Also, we offer semi-portable expansion machines as well. For example, the Flexpander-FE is one of our most popular models. The FE model can expand two tubes per cycle which then allows it to expand coils with a U-bend or straight tube.
