Introducing E Size Acetylene

Simon Bishop 2017-12-02T17:21:10+11:00 Categories: Acetylene|Tags: Acetylene, E Size Acetylene, welding gas, Welding gas kit|

Acetylene E Size Cylinder Now Available - December 2017: Sydney Only Great news we now have Acetylene available in E size cylinders for our Sydney customers. Acetylene is a fuel gas that is ideal for cutting, flame hardening, and Oxy-Acetylene welding. You can now purchase your own cylinder and have it delivered to you for one price including the gas, cylinder, and GST. Whenever the cylinder requires refilling, we come to you and swap it over fora full cylinder. Simple. Our brand new E size Acetylene cylinders hold 3.2m3 of Acetylene and are free of asbestos, unlike other suppliers in the market. In terms of welding quality, with a heat transfer rate of 3,100C, oxy-acetylene is the best cutting & heating gas available. A research project conducted over 2008 and 2009 by the German Federal Institute for Materials Research and Testing concluded that acetylene was a safe gas. It highlighted that mechanical impact alone cannot initiate acetylene decomposition, that only a cylinder that had been exposed to direct fire was at any risk of decomposition, and that one-hour cooling was enough to ensure that no decomposition was ongoing in these cylinders. The cylinders must be stored in an upright position that doesn’t allow for falling or knocking over, must not be rolled, and when handling them one should wear eye protection, safety shoes, and gloves. Rent Free Gas is able to supply customers with Acetylene for a multitude of uses, but our customers primarily use our Acetylene for welding and cutting. Our rent free model allows our customers to purchase their own Acetylene cylinder which they will never have to pay rent on and that will come completely full of gas, delivered for free to Sydney.

Mig Welding Gas kit - Starters Gas Kit for Welding (C, D & E Size Cylinders). We have recently put together a Mig starters (Argon 5/2 mix) gas kit, which includes a new refillable C size (0.6m3) bottle full of gas, with a new Argon regulator (Type 10 valve outlet) and an inert gas hose rated to 1500kpa. The kit price also includes GST and delivery to you. The C size cylinder can be delivered to customers Australia wide. WA/NT customers will need to call us to obtain a delivery cost as it is expensive to freight goods to WA/NT. The Mig Gas kit which includes a cylinder of Argon 5/2 mix is also available in D size (1.6m3) for $400 (which includes the gas, hose & regulator) and the E size (4m3) for $500 (which includes the gas, hose and regulator), are available for free delivery in Sydney only. In your order please specify if you would like Argon 5/2 mix for Mig welding or Pure Argon for TIG, Aluminium or stainless. The photo below is an example of the C size cylinder connected to the regulator and hose. The system works the same with the D and E size.

Why owning your own cylinder is the best deal on the market today.

Don't be fooled by so called 'Rent Free Deals' As time goes on the big gas guys are coming to appreciate that continuing to charge rent on their cylinders is causing their customers to look and shop elsewhere. Many of them have introduced new schemes in attempt to keep their customers. Some of these schemes involve a single ongoing charge per year or a large deposit to be returned once you no longer need your cylinder (which is unlikely, oh and don't forget your receipt that you put somewhere 3 years ago!) Don’t be fooled by these deals...at the end of the day you are still paying them for the privilege to use their cylinders. So whilst they may use the term ‘no more rent’ they have swapped rent for another type of payment. These schemes are also only for a small selection of gas types and cylinder sizes rather than their full range. So how is Rent Free Gas different? Well, buy one of our cylinders and that is exactly what you are doing….buying your own cylinder. Aside from the cost of a refill you will never pay another cent for the privilege of owning your own cylinder. We simply swap over your cylinder whenever it is empty. You don’t need to worry about maintaining your cylinder, we do all the hard work for you making sure each cylinder is checked regularly to meet Australian standards. So don’t be confused by some gas deals offering no rental costs, no rent means owning your own cylinder and that is exactly what Rent Free Gas can help you out with today. So give us a call on 0404677187 to have a chat about how we can take the hassle out of buying gas and make sure you get a true rent free deal.

Welding Gas, Pure Argon v Argon Mixtures

Argon Welding Gas Argon gas is commonly used in joining metals together or welding. The purpose of including Argon is to protect and shield the welded area from air, Oxygen and moisture. When any or all of these elements get into the welded area it will oxidise and thus weaken the join. Argon is used because it is firstly inert, or non-reactive so it does not affect the welding process. Other gases that are inert, but that are not as effective as Argon include CO2 and Nitrogen. Nitrogen is reactive at higher pressures and CO2 is used in mixtures with Argon. Secondly, Argon is more commonly used today as it is cheaper than other non-reactive noble gases, such as helium. There are a few types of Argon sold for welding applications. Pure Argon is used for applications including stainless steel, Aluminium and TIG welding of plate, tubing and sheet metal. Pure Argon is also suitable for MIG welding of Aluminium. Argon 5/2 is a mixture of 93% pure Argon with 5% Carbon Dioxide and 2% Oxygen. This blend of gas is a common welding mixture in Australia for MIG welding applications. The Argon 5/2 mix has good general properties around minimising weld spatter, good flow (allowing a fluid weld pool) and helps in creating a good welded appearance on your job. This mixture works well with MIG welding for mild steel, stainless steel, low alloy steel and galvanised steel, where the thickness of the steel is up to around 8-9mm. The addition of the Oxygen and Carbon dioxide into the Argon helps to give the arc more stability, but as mentioned earlier, it also allows the The addition of the Oxygen and Carbon dioxide into the Argon helps to give the arc more stability, but as mentioned earlier, it also allows the welder's pool to be more fluid, giving a nice presentation. Over the years we have also made specific welding mixtures for customers which include [...]

Nitrogen Gas and Air Conditioning Market

Australian Refrigeration Council & Nitrogen Gas The rentfreegas nitrogen kit comes with Nitrogen gas, a regulator (0-1000kpa) and a pressure rated inert gas hose, has been designed to put the necessary components together so that our customers can purchase everything they require to get started in the refrigeration and air conditioning industry. If you require a higher pressure regulator between 2000-6000kpa we have those in stock as well. Some customers are using the nitrogen for cold brew coffee applications and plastics welding, whilst other customers are using it to pressurise and pure oxygen out of food lines, or in brewing applications. More recently we have had customers purchase the kit to help them comply with the Australian Refrigeration Council requirements for their refrigerant handling licence (RHL). The ARC site states that: “Where the RHL (Refrigerant Handling Licence) holder uses dry nitrogen to test equipment to detect leaks, reference must be made to the vehicle manufacturer’s service guidelines” The Australian Refrigeration Council states that all companies or individuals that hold a Refrigerant Trading Authorisation under the Australian Government’s Ozone Protection and Synthetic Greenhouse Gas Management Regulations 1995 will have a permit condition check conducted by the Australian Refrigeration Council (ARC). The Australian Refrigeration Council (ARC) also have some forms or document templates that help you as an RHL holder report on the necessary elements of the audit and maintain the proper records. We have attached a link below to the auditing requirements. Link below…. https://www.arctick.org/business-authorisation/auditing/

Argon Gas for Food Preservation

Most people think of welding when they think of argon gas. In fact, argon is a safe, benign gas which can be used to preserve wine, food and historical documents. For some time nitrogen was the ‘go to’ gas when it came to extending the shelf life of packaged goods but scientists have found that argon is actually 4 times more efficient than nitrogen, it is also around 40% denser than air and improves food safety. Thus argon is more effective than nitrogen in keeping food fresher for longer and improving its quality. So how does it work? Gas is used to replace oxygen which not only causes food to oxidise and spoil but allows bacteria to grow. Argon removes the oxygen very efficiently compared to nitrogen as it is denser and is able to more completely fill the spaces around food. Bacteria is starved of oxygen and enzymes that increase the rate of oxidation are inhibited. The use of food grade argon as a preserver does not add anything to the original product, rather it stops it from going bad in a completely safe way. Rent Free Gas is able to supply customers with food grade argon for a multitude of uses including the preservation of food and wine. Our rent free model allows our customers to purchase their own argon cylinder which they will never pay any rent on...ever! The cylinder will come completely full of gas and delivered for free in Sydney, Brisbane and Adelaide. Whenever more gas is needed we will simply come out and replace the empty argon cylinder with a full bottle. If a smaller c size cylinder is all you need we can post it to you anywhere in Australia. Give us a call and let one of our friendly team help you out with your argon gas needs today.

Nitrogen Gas Delivery

Simon Bishop 2017-07-09T16:26:47+10:00 Categories: Gas cylinder delivery, NITROGEN GAS CYLINDER|Tags: Gas Delivery, Nitrogen gas delivery, Sydney delivery|

Nitrogen Gas Cylinder Delivery in Sydney When you own one of our Nitrogen gas bottles or a Speedgas Nitrogen gas cylinder, you can stop paying rent immediately. If we give you a refill price, there is no more to pay, there are no other costs. We cannot refill BOC, ALA, Supagas or Coregas cylinders. We cannot refill BOC, ALA, Supagas or Coregas cylinders. Our customer base is growing very quickly and the two main reasons for this are that we keep things simple (for example, no invoicing issues), and also because we are saving our customers money. We ask you to think about how long you have had a cylinder sitting in the workshop, garage, factory, shed or office? If the answer is a long time (more than a few years) to that question, then you should send the bottle back to your supplier and buy a bottle of your own. Information provided from customers who have purchased their own bottle (that comes with no rent and no delivery), is that after about 12-14 months they have saved money. Their rental costs vary between $10-$25 per month which is $120-$300 - just for rental. So once you add in the gas cost on top of that rental, you are normally in front after 1 year. The next key question is how often you refill that Nitrogen bottle? If your answer is not very often (let's say a few times per year) then you should definitely review your refill costs and give us a call. We will match the big guy's price, and do a deal to get you saving money today. There are no tricks or hidden costs with Rentfreegas and Speedgas, we are a small and nimble AUSTRALIAN business that wants to talk to you and help you with great service, and also help you lower your nitrogen costs. If you would like more information about rent free gas bottles or how to lower industrial gas costs in your business, feel [...]

Introducing New Nitrogen Gas Kit

Nitrogen Gas, Regulator and Hose Kit Nitrogen Gas & Reg Kit We have recently put together a Nitrogen gas kit, which includes a new refillable bottle full of gas, with a new Nitrogen regulator (Type 50 valve outlet) and an inert gas hose rated to 1500kpa. The kit price also includes GST and delivery to you, so for $310 you can own a refillable gas cylinder, regulator and hose, delivered to you. In some kits we have already supplied customers, they requested for us to attach a simple low-pressure air gun with a trigger mechanism to the other end of the hose. The airgun allows customers to pulse quick or long bursts of nitrogen into bottles, bags and food containers for purging, or to fill other items and balloons quickly. Nitrogen is used in many areas and industries, some of these include, automotive for filling car tyres, food & wine preservation, welding, aviation, fire protection, refrigeration, fumigation, and for purging lines, oxygen depletion, plastics welding and much more. Once you own your own Nitrogen gas bottle, you never pay cylinder rental again. When the bottle is empty you place it back into the box it arrived in and return it through the post, then purchase your C size cylinder 'refill' from our store at http://www.rentfreegas.com.au/shop/nitrogen/ which costs $70. Then the following day we send you a full bottle. If you have any questions, please feel free to call us. Regards, www.rentfreegas.com.au Phone: 0404 677 187
