Plastic Tubing … A Clear Choice

Tuesday, March 16th, 2010

Flexible. Tough. Resistant.  Environmentally-Friendly. And recognized by nearly every industry in the world, clear plastic tubing has been a product of choice by worldwide manufacturing companies to small businesses to pet owners.
So what makes a seemingly simple product like clear plastic tubing so desirable to such a diverse audience?

-  First, whatever the industry or the application, the choice to use clear plastic tubing to perform various functions—from flow lines to transport liquids to using it for air supply on 200-gallon fish tank—PVC clear tubing (how it’s also known) consistently delivers reliable performance time and again.

-Second, clear plastic tubing is available in a wide range of sizes, thicknesses, and lengths that makes it easier to adapt to the need.

-Third, the properties of clear plastic tube make it more durable than most alloys for certain applications, and as a result clear plastic tubes can also be more cost-effective, as well as a “green” choice.  By using such a long-lasting product like clear (transparent) plastic tubing, companies are essentially decreasing their expenses as a result of not needing to replace the polyethylene (plastic) clear tubing as frequently on their equipment due to its strength and resistance to wear and tear. And also, it reduces their yearly waste disposal that essentially eases the negative effects on landfills and the environment.

After all, in today’s new business economy, what company isn’t trying to reduce expenses and their carbon footprint?

And to think, it’s all possible because of clear plastic tubing.

Go with the [clear nylon tubing] flow

Tuesday, March 16th, 2010

Thanks to scientists at DuPont back who invented nylon in 1931 numerous industries have been afforded the opportunity to manufacture a myriad of products because of this highly durable “miracle fiber”—products such as clear nylon tubing . And if you live in the Northeast, you may appreciate its introduction to the industrial world even more so—particularly knowing that clear nylon tubing is available for purchase.

Being exposed to freezing temperature during the winter months can cause its share of problems. Before you know, it’s only early January and a coat of ice has covered everything from your walkway to a tree limb. But did you also know that your well pump could be comprised if you’re not using clear nylon tubing?

The last task you want to be undertaking in the winter is a tubing replacement project for your well pump, which is why clear nylon tubing is highly recommended for this application purpose. It will not become brittle or swell because of water. And best of all—nylon tubing can withstand subfreezing temperatures.

With a high quality clear nylon tubing installed, you can be assured that if the pump stops working and no water is running through the tubing, that the clear nylon tubing will continues to perform in these harsh conditions when the pump becomes operable again.
And given clear nylon tubing’s resistance to corrosion and stress-cracking the result is obvious– you have flowing water!

Who would have thought that clear plastic tubing could be one of the single most important components to transport a water supply?

Have it your way—but can it be manufactured?

Tuesday, March 16th, 2010

Unless you’re a design engineer of custom made tubing you may not be as curious as to how custom tubing is made, or why it is important to consider custom tubes specifications closely before embarking on the manufacturing process.

More often times than not, tube designers push the manufacturing envelope when they design custom made tube with requirements that are not necessarily advantageous for the products intended use. It’s not intentional to make the manufacturing process of custom tube more difficult, rather a goal of developing the perfect end product.

But what they should be asking themselves during the design phase is, “what are our critical requirements for this product?” Otherwise, what is often realized too late can be costly and also cause delays in production of the custom made tube. To avoid such stumbling blocks, there are several criteria that tube designers should consider during the custom tubing planning process:

  • Material specification – have you considered the best thermoplastic suited to the application of the custom made tube?
  • Configurations – are your design specifications realistic so that the custom tubes can be manufactured?
  • Manufacturability – is your design dimensions and tolerances feasible and would you consider re-evaluating your tolerances to facilitate the process of making a high quality custom made tube more efficiently?

From the time that plastic was first introduced into mass production, custom tubing companies have been afforded the opportunity to create a myriad of products from extruded plastic rods to single-lumen tubing. And like the world of imagination, custom made tubes have endless possibilities—but proper planning will make it a success.

Polypropylene tubing vs. Steel tubes in solar heating systems…and the job goes to?

Tuesday, March 16th, 2010

Curiosity may have killed the cat! But curiosity about the benefits of polypropylene tubing used in solar heaters is a different story altogether. This is particularly true whether you’re a design engineer responsible for making decisions concerning the tubing material for solar heating equipment, or a homeowner deciding to install a solar heating system.

Here’s why.

While polypropylene tubing may be used in a number of applications, its potential use in solar water heaters spawned scientific interest.  A recent study reported on its experimentation of testing whether polypropylene tubing would perform better than steel tubes in the heat transfer rates.   It was concluded that polypropylene tubes would in fact be the ideal choice, over steel tubes, as the polypropylene rod increased the rate of heat transfer by 10 degrees Celsius.

Based on these results, one could conclude that design engineers may specify polypropylene rod in the design of solar heating systems; passing those benefits on to the end user, in this case, the homeowner. As not only is installing a solar heating system with polypropylene tubing suggested to be environmentally beneficial, it also offers a cost-savings benefit in two distinct ways: First, users will save on energy costs by using solar heating, and second, they can also take advantage of a federal tax credit offered to taxpayers for installing energy efficient systems.

Of course, this is simply a cursory view of the benefits of polypropylene tubing.  But it may just be your link to your finding a custom tubing manufacturing source that will serve your polypropylene tube needs — whether for a solar heating system or any other application deemed appropriate.

Sure it’s strong, but will it melt?

With dual wall tubing —what you see on the outside is not all that you get. Flexible. Moisture proof. Heat-shrinkable. What more could ask of dual wall tubing? While the outer jacket is comprised of an abrasion resistance material necessary for strength and durability, its inner chamber is made of a compound that protects against environmental conditions like water, moisture and corrosion.

What you may not realize is that its tensile strength is suitable for use for auto wires, shipping cables, and bundle wires. Yet dual wall tubing is constructed of a meltable adhesive liner that will permit it to heat shrink which helps to form a protective barrier over the wiring protecting it from chemicals and oils. This symbiotic relationship of dual wall tubing is necessary to ensure both layers maintain its properties.

While many other tubing’s performance is compromised by extreme weather fluctuations, flexing or by severe vibration, dual wall tubing can absorb the strain like a pro.

Are you considering dual wall tubing for marine and wire splices? It’s the best alternative to heavy wall tubing. And taking into consideration the constant exposure to water and moisture in this particular application, dual wall tubing will provide protection.

Perhaps dual wall tubing is need for shipping cables? Its corrosion resistance properties make it an ideal choice. Regardless of the application for which it is being used, dual wall tubing is constructed to deliver optimum performance.

Why Collaboration Works in Manufacturing Medical Tubing

Tuesday, March 16th, 2010

With such rapid advances in the medical industry, medical tubing manufacturers recognize the unique opportunity to partner with their customers to develop new medical tubing products.
It may not be the first time in history that innovation has necessitated this type of collaboration between a manufacturer and a designer. But when it comes to delivering superior healthcare, the partnership between a medical tubing company and its customers is paramount to success as the complexity of medical procedures keeps changing.

As stated, the impetus for a medical tubing manufacturing company to get involved with design engineers at the development level arises out advancements made in the medical profession. This requires the continual development of more sophisticated, high performing medical devices, surgical instruments, and other specialty medical equipment; which in turn requires more complex medical tubes that are used for the particular application.

Thus the role of the medical tubing manufacturer becomes two-fold: To manufacture the customers’ medical tubing product; and to also ensure that the medical tube can be manufactured to its specifications and still perform reliably.

Often times design engineers have very creative and complex design ideas for medical tubes that can push the limitations of the properties of the thermoplastic being used. In other words, the medical tubing manufacturer has to insert themselves at the early stages of development to guide the customer to select the right material, configuration, tolerance, etc. so that the medical tube functions in accordance with its requirements.

And when and if the original custom tubing product fails, the medical tubing supplier will recommend ways to improve the design until it works properly. It’s an ongoing cycle of innovation.

The Reliability Factor of Custom Tubing

Tuesday, March 16th, 2010

The importance of small diameter custom tubing can be as easily overlooked as the necessity of a pen cap—unless you’re the end user in a life-saving capacity who depends upon the custom tube to function reliably to help you do your job.

While a pen cap is obviously less mission-critical than that of custom tubing, of course, the principals are the same. For a product to perform properly, it is imperative that all the components are of the highest quality to ensure it meets those standards of performance.

For equipment that requires custom tubing–whether it’s a custom tube utilized in a cardiac catheter packaging that may later be inserted into a patient’s heart to keep him alive or custom tubes used in pharmaceutical lab equipment to dispense liquid. The custom tube must meet numerous quality standards, in this case, to be puncture and wear-resistant, flexible, and act as a protective barrier to outside elements that could compromise its function.

People would be surprised to learn about how much design, planning and quality control goes into manufacturing these perfectly cylindrical, small diameter custom tubing; and how each custom tube is manufactured to maximize performance depending on the specific application.

Is the custom tube for a one-time use? Will it be exposed to heat? Which type of thermoplastic should the custom tube be manufactured in – PVC, Nylon, or Tecoflex™?

From medical facilities to electronic companies– numerous industries depend upon manufacturers who specialize in small diameter custom tubing, companies like A.P. Extrusion who work with their customers to ensure quality is never compromised.
