Best Ways To Dry A Plastic Tube

how to dry a plastic tube

Drying a plastic tube is a crucial step in maintaining equipment, especially in winemaking and homebrewing. While some people accept residual moisture, others seek comprehensive drying methods. Centripetal force, achieved by spinning or swinging the tube, is a popular technique to expel water. Other methods include using an air compressor, a hairdryer, or a vacuum to blow air through the tube. Sanitization is also important, with some sources recommending hospital-grade sanitisers or baby powder to prevent mould and ensure equipment longevity.

Using an air compressor

When using an air compressor to dry a plastic tube, start by getting as much water out of the tube as possible through mechanical means. You can do this by shaking the tube vigorously or swinging it in a circular motion to use centrifugal force to remove most of the water.

Next, attach a small hose to the wet tube, and then connect the hose to your air compressor. Ensure that the air compressor is set to deliver dry air at an appropriate pressure for plastic tubing. Start the compressor and allow it to blow air into the tube at a rate that keeps the tube mostly inflated while circulating air inside. Leave the compressor running for several hours or even a full day to ensure the tube is completely dry.

It is important to note that not all plastics are suitable for use with compressed air. Some plastics, such as PVC, ABS, CPVC, and PVDF, are not formulated to handle compressed air and may shatter, creating a safety hazard. Instead, opt for tubing made from polyethylene or polyurethane, which are safer alternatives for use with compressed air.

Finally, always inspect your tubing for any signs of damage or deterioration before using an air compressor. This ensures that the tubing can withstand the pressure and avoids any potential hazards.

Hanging vertically

Hanging plastic tubing vertically is a popular method for drying it. The process can be done outside or in a room with a hook or cabinet handle to hang the tubing on. The tubing should be hung so that its two ends are pointing downwards, allowing any remaining liquid to drip out.

To speed up the drying process, the tubing can be swung around in a full circle before hanging. This action uses centrifugal force to remove most of the water, leaving only small droplets that can be left to air dry.

Another method to speed up the process is to use an air compressor to blow air into the tube. This can be done by attaching the compressor to one end of the tubing and allowing air to circulate through the tube while keeping it mostly inflated.

For those without an air compressor, a hair dryer can be used to blast hot air into the tube through a small plastic funnel held at one end.

Hanging plastic tubing vertically and using these additional techniques can effectively dry the tubing before putting it away for storage.

Spinning and swinging

To dry a plastic tube, it is recommended to first spin the tube around above your head like a lasso. Centripetal force will cause most of the water to come out. You can also swing the tube in a 360 like a helicopter. The centrifugal force will make most of the droplets fly out, and the remaining drops will be small enough to air-dry.

After spinning and swinging, you can hang the tube completely vertically to dry it out quicker. You can also use an air compressor to blow-dry the inside of the tube. If you don't have an air compressor, you can use a hairdryer to blast hot air into the tube.

If you are drying a boat tube, you can fill the tube with air, make the valve the low point, and use a shop vac to suck the water and air out. Repeat this process multiple times. You can also use a vacuum that has a blower function and wedge the hose into the boat tube to inflate it and exhaust the air through the tube.

Using a hair dryer

Hold the hair dryer at a safe distance from the tube, around 6-12 inches away, and turn it on. Direct the airflow towards the tube, ensuring that you cover all areas, including any crevices or bends in the tube. Keep the dryer in constant motion to avoid concentrating the heat in one area for too long.

Depending on the thickness and length of the tube, you may need to dry it in sections. Start with one end and work your way towards the middle, then repeat the process for the other end. This ensures that the heat is distributed evenly and prevents any warping or damage.

It is important to be cautious when using a hair dryer on plastic, as the material can become soft and pliable when heated. Keep children and pets away from the area while drying the tube, and ensure that the space is well-ventilated to prevent any potential fumes from the heated plastic.

Finally, once you have dried the tube thoroughly, allow it to cool down completely before handling or using it. This will ensure that the plastic retains its shape and that no condensation forms inside the tube.

Using a sponge

One method for drying a plastic tube is to use a sponge. This can be done in several ways, each with its own advantages and considerations. Here is a step-by-step guide on how to dry a plastic tube using a sponge:

Preparing the Sponge

Start by cutting a sponge to fit snugly inside your plastic tube. The length of the sponge should be slightly shorter than the tube to ensure it can be easily inserted and removed. Wet the sponge before use to help remove any debris from the tube.

Cleaning the Tube

Insert the wet sponge into the tube, and then attach the tube to a faucet. Let the water pressure push the sponge through the tube. The sponge will help dislodge any stubborn material or residue inside the tube. This method is especially useful for removing small specks of yeast or hops that can get stuck during brewing processes.

Drying the Tube

After cleaning, the tube can be dried using various techniques. One method is to hang the tube with the ends facing down to allow gravity to help drain the water. You can also swing the tube in a circular motion to use centrifugal force to remove water droplets, ensuring that any remaining drops are small enough to air-dry.

Additionally, you can use an air compressor to blow dry the inside of the tube. If you don't have an air compressor, a hair dryer can be used to blast hot air into the tube, effectively drying it.

Sanitation

To ensure complete sanitation, it is recommended to sanitise the tube before and after use. Some people use sanitising solutions like StarSan or Oxyclean, allowing them to sit in the tube for a few minutes before rinsing. Others prefer to use boiling water or hospital-grade sanitisers to kill any potential bacteria.

Maintenance

Regular maintenance of your plastic tubes can help prevent mould or bacterial growth. While some people recommend replacing the tubes frequently, proper cleaning and drying techniques can extend their lifespan. Remember to always rinse the tubes with hot water after use and hang them up to dry.

By following these steps and adapting them to your specific needs, you can effectively dry a plastic tube using a sponge and ensure its cleanliness and longevity.
