Our Remodel Story

We purchased a house in 2015 with the intention of doing a full remodel.  We had never done this before, but armed with ideas and a great contractor, we started on January 4, 2016.  That time of year is an awesome time to remodel because subs are looking for work and the project, if planned well, will move quickly.  That time of year is not-so-awesome if you are living in the remodel, which we were.  The contractors demoed the kitchen on January 4, and I did not have a place to cook again until early March.  I didn’t think this would be that big of an obstacle because I am creative, and I had a barbecue–I planned to grill all winter.

Little did I know, propane freezes, and this winter would be one of the coldest on record for Utah.  Needless to say, my winter grilling plan did not work and we ate out a lot.  I wish I had known more about propane and about Powerblanket propane tank heaters.  This knowledge would have saved me a great deal of headache and money.

Propane Tanks Can Freeze

Propane tanks can freeze while in use. The colder it is outside, the lower the pressure will be in your tank; conversely, the higher the temperature, the higher the pressure. Liquid propane volume is directly related to its temperature.  When the ambient temperature is very cold, especially below zero temperatures, there may not be enough pressure in your tank to keep your system/appliance working properly. Gas volume is determined by the number of molecule collisions occurring within the container, and these collisions decrease/increase with the temperature.

Product Spotlight: Gas Cylinder Heaters

Do you store gas in cylinders? If so, then you know how the cold can affect them, even during this mild winter. In order to keep your storage from being compromised by a drop in temperature, you need a solution that can both insulate and heat. This is where Powerblanket® Gas Cylinder Heaters come into play.

 

Pressure and Depletion

Let’s face it, this is one of the mildest winters North America has seen in a very long time, but that doesn’t mean that it isn’t getting cold enough to affect equipment and resources left out in the dropping temperatures, even though they aren’t dropping as low as usual. As far as gas storage goes, if you’re storing it in gas cylinders, you’re likely keeping it outside, and if it’s outside, it’s going to lose pressure—causing depletion and problems with extraction.

When you store pressurized gas in cold temperatures, or any temperature below ideal, then the pressure in your tank is going to be far less than efficient. This is simply due to the molecules of gas moving closer together, just like in your car’s tires. And of course, as the molecules move closer together, the pressure drastically drops. This means when it comes time for extracting the gas from your tank or cylinder, you’re going to run into troubles; it’s going to seem like there isn’t as much gas in there.

 

Powerblanket® Gas Cylinder Heaters

Powerblanket® Gas Cylinder Heaters solve this problem by adding a protective barrier that both insulates and heats your tank or cylinder to the ideal temperature needed for optimal pressure maintenance. Powerblanket offers a range of gas cylinder heaters equipped for maintaining temperatures of propane, butane, nitrogen, oxygen, and other compressed gases. Powerblanket® Gas Cylinder Heaters offer uniform heat distribution across the entire cylinder. This revolutionary heating solution reduces costs by optimizing container temperatures and increasing cylinder efficiency.

What’s more, the Powerblanket® product line is designed for any heating job. Every product is built using a rugged vinyl shell that is safe to use in temperatures as low as -20° F. So in other words, Powerblanket products can keep your equipment protected well below freezing.

 

Standout Features

  • Increases performance and efficiency of gas cylinders
  • Provides even heat distribution
  • Saves money by optimizing gas and material usage
  • Safety certified by UL/CSA/CE
  • Eliminates unnecessary cylinder refills in cold weather

 

 


Welding Preheating

Welding Preheating

Prepping pipes and other surfaces for welding can be a real challenge since metal surfaces often need to be hot before you begin. If the metal isn’t hot enough before you start welding, it will affect the cooling rate. If a weld cools too quickly, the metal could go into shock and cause fabrication hydrogen cracking. There are many metal preheating methods. Some of these include: furnace heating, torching, electrical strip heaters, induction heating, and radiation heating, and welding preheat blankets.

Why Preheat Metal?

When you preheat and post-heat the metal, it allows for better hydrogen diffusion; up to 1000 times more diffusion at 250 °F (121 °C) than at room temperature (68 °F, 20 °C). Cracking risks reduce as more hydrogen diffuses after the weld is complete.

Types of Heat Transfer

There are 3 main types of heat transfer: convection, radiation, and conduction. All 3 methods are useful in different applications. Let’s take a closer look.

Convection

Convection transfers heat around a space by the movement of molecules. For example, the rolling circular motion within a pot of boiling water is convection heating.

Radiation

Radiation is the transfer of heat through electromagnetic radiation. Radiant heating is what you can feel in the air when you sit around a campfire.

Conduction

Conduction transfers heat through direct surface contact. This is the most efficient heat transfer method to use when preheating a wide variety of metal surfaces for welding. Radiant heat will waste time and energy heating the air around the metal instead of the metal itself. Direct contact will ensure even, consistent heat over the surface of your welding materials.

Let’s compare 2 different welding preheating methods. Induction heating using radiation and heating blankets using conduction.

Induction Heating vs. Heating Blankets

Induction heating involves coiling a conductive metal object around the surface or container that needs to be heated. Electromagnetic currents then circulate and heat the object they surround. Once these metal coils are in place, they are not easy to remove and re-install. Induction heating is well suited for objects needing continual applied heat in a fixed, controlled location. Induction is commonly used in factories, where long strips of piping are continuously fed through the center of inductive heating coils.

However, for field work welding and on site repairs, induction is not a practical solution, especially in colder weather. Welding in a dynamic environment requires more portable and flexible preheating options. High temperature heating blankets are flexible enough to conform to and heat any metal in need of welding. They also use conductive heating that evenly distributes across the entire metal surface.
