What Type Of Forklift Propane Service Is Right For You?

If your business uses forklift propane, you are undoubtedly on a delivery service of some kind, but is it the best type of service for your use? Under-delivery can result in costly down-time while you wait for additional gas, but you shouldn’t be paying for more propane that your forklifts, floor sweepers, and scissor lifts can possibly burn. What’s the right balance for your operation?

Types Of Forklift Propane Delivery

  • Cylinder Exchange – If your company occasionally uses a few pieces of propane-powered equipment, or regularly uses one or two on a predictable schedule, cylinder exchange makes good sense. You trade your empty cylinder for a full one when you need it or schedule automatic, periodic deliveries, and it is simple and affordable to keep an extra on hand, just in case.
  • On-Site Re-Filling – Companies that run several pieces of equipment on propane may find on-site cylinder re-filling a better value than cylinder exchange. This is especially helpful when your equipment uses propane at vastly different rates from each other, or when you have cycles of heavier and lighter use. The bulk delivery truck will come on a pre-set schedule and fill each tank as needed.
  • Bulk Tanks – For companies that run lots of propane-powered equipment on a consistent basis, a bulk tank may be a sensible investment. With a bulk tank, you can re-fuel all of your propane equipment on-site, so it offers the best flexibility of all options. There is an initial investment involved in getting the required permits and leasing or purchasing the tank and transfer equipment, but if you’re using a high volume of propane, the investment will likely be well worthwhile.

How Does Liquid Oxygen Improve Wastewater Treatment?

Liquid Oxygen helps biological wastewater treatment plants by increasing their capacity and by helping to settle upset conditions quickly. Upset conditions include times of high Biological Oxygen Demand (BOD); high sludge volume index, also known as bulking; and abnormal production of sulphurous odours. All of these conditions are the results of low dissolved Oxygen in the sludge, and can be rapidly remedied by injecting Oxygen.

Keeping Things Regular

A typical biological plant strives to maintain two to three milligrams per litre of dissolved Oxygen in its biobasin. This level ensures that the biomass has enough Oxygen to metabolize efficiently, and it helps control the population of filamentous bacteria. Some filamentous bacteria are needed in the biomass as a foundational component of the bacterial mesh that helps separate the liquids from the solids in the system. When these bacteria are allowed to overpopulate, though, the solids in the system no longer settle properly, and the whole system becomes less efficient. An overpopulation of certain types of filamentous bacteria can also cause foaming, which also has a negative impact on the plant’s operation, and can actually cause the tanks to overflow, which creates hazardous and disgusting work conditions.

Oxygen To The Rescue

Historically, aeration systems have been used in biological wastewater treatment plants to try to address these issues. A typical aeration system increases the amount of Oxygen in the system by 10-15% (air has about 21% Oxygen). More recently, plants have begun using pure Oxygen transfer systems, which use liquid Oxygen (LOx) and specially designed delivery devices to achieve Oxygen transfer on the order of 70-90%. Other plants have modified their aeration systems to accept Oxygen enrichment, which significantly boosts the Oxygen transfer rate. With either a pure Oxygen transfer system or Oxygen enrichment on an aeration system, plant managers get much finer control over their biomass and tank conditions, and faster response in a crisis.

Argon Gas Creates Perfect Atmosphere For 3-D Metal Printing

Argon gas has found another important use as the popularity of Metal Additive Manufacturing, or 3-D metal printing, grows across a variety of industries. The process, which uses lasers to melt ultra-thin layers of atomized metal powder to build a three-dimensional part one layer at a time first gained popularity for rapid prototyping. As the technology has improved, though, it is now being used to manufacture precision parts used in industrial, aerospace, medical and dental, and automotive applications.

An Ideal Environment For Selective Laser Melting

Because the lasers involved are selectively melting micro-fine material to produce these precision parts, any oxidation or impurities like nitrides introduced into the fabrication environment could easily ruin the run. Argon gas is inert, so it prevents oxidation and is not flammable. Argon is used to reduce oxygen concentration in the manufacturing area to less than 500 PPM (parts per million), which essentially eliminates the possibility of oxidation during the manufacturing process.

Man-Made Medical Miracles

As Metal Additive Manufacturing has become commercially viable, in terms of both cost and possible output, it opens a vast assortment of potential uses, producing objects which were simply not feasible using previous manufacturing techniques. It is already being used to fabricate parts for planes, spacecraft, and cars, along with custom-made orthopaedic and dental devices. Imagine someone who has suffered massive injury to their facial structure. Until very recently, doctors were limited to using “off the shelf” shapes to rebuild that patient’s face. It is now possible to construct implants designed to imitate that specific patient’s facial structure, and restore them to a much more natural appearance. Imagine precision-made dental implants, partials, or bridges, instead of clunky, molded approximations of imprecise impressions. Imagine doctors being able to custom design replacements for injured joints. These are no longer the stuff of science fiction.

Improving Industry

One area where Metal Additive Manufacturing is making a big splash is in the production of injection molds. In addition to tighter tolerances, 3-D metal printing allows for more complex and efficient cooling channels to be built into the molds which shortens cooling time, improves cooling performance, and extends the useful life of the mold itself, so there is less waste. Because 3-D metal printing allows for bespoke functional parts to be produced quickly and without the expense of tooling, it lends itself beautifully to research and development of production automotive parts, in addition to specialized parts for racecars. The process is also lending itself to advances in aerospace because, among other benefits, it allows researchers to develop parts that are lighter in weight, often with improved function. And lighter planes consume less fuel, which reduces the environmental impact.

Choose The Right MIG Welding Wire To Boost Your Bottom Line

A shop should never skimp on filler materials. But, unfortunately, welding wire is one place where some shops try, unsuccessfully, to economize. It is a new year, and everyone is planning ahead for a more profitable year. If your shop does a lot of MIG welding, you may be considering switching to less expensive wire to help boost profits. Sadly, this can prove a false economy, and in the worst case, could even cost you more than sticking with better quality product. If you are looking for ways to save money this year, here are some important considerations:

The True Costs Of Cheap Wire

  • Manpower – If you are like most shops, you probably spend around five percent of your welding budget on actually purchasing wire. The lion’s share of the budget goes to overhead and labor. Switching to inferior wire can result in more pre and post weld operations, which eat up your labor productivity and add wear and tear to your machinery.
  • Quality Assurance And Waste –Welding with inferior wire often produces more failed welds, and increases your waste. The less consistent your welds are, the more diligent and time-consuming your quality inspections have to be. Even in a robotic welding shop, low-quality wire takes its toll, because imperfections in the wire can lead to imperfect welds that require human re-work.
  • Your Reputation Is On The Line – Shipping defective product damages your company’s reputation for producing consistently high-quality products. Managing unsatisfied customers and shipping replacement product is costly, but even more costly are the customers who “go away mad” without saying a word to you. Rest assured, they will have plenty of words for other potential customers.

Ways To Achieve Genuine Economy

  • Get It Right The First Time – Higher quality welding wire tends to perform better, even in less-than-ideal conditions. Your staff can spend less time on prep work and re-work when they are using premium welding wire.
  • Consistent Diameter – When you choose welding wire from a premium manufacturer, you know you are getting consistent diameter, down to the last few microns, because it is inspected and verified with a laser micrometer. Variation in wire diameter can cause arcing, if the wire has an undersized section. It can cause wear and tear on your tips, if the wire has a “fat” section. Save your equipment, save money.
  • Chemical Consistency – As with diameter, variations in the chemical consistency of your wire can wreak havoc on efficiency and equipment. Quality wire includes quality assurance.
  • Is Bulk Best? – If you are running a high volume shop with robotic welding, bulk purchasing makes sense, and will save you money. If you are producing more moderate volume, you may be unnecessarily tying up capital and floor space to buy and store bulk wire. A good guideline is to buy what your shop can use up in 30 to 40 days.
