Does MAPP Gas Burn Hotter than Propane? An In-Depth Analysis If you're looking for a hotter torch flame for your welding or brazing projects, you might have heard of MAPP gas and propane. Both gases are commonly used for heating applications, but which one burns hotter? In this article, we'll explore the properties of MAPP gas and propane and compare their flame temperatures to answer the question: does MAPP gas burn hotter than propane? What is MAPP Gas? MAPP gas stands for methylacetylene-propadiene propane, a fuel gas mixture that contains propylene and propane. It's a colorless, odorless gas that's compressed into a cylinder for use in torches and soldering irons. MAPP gas was first introduced in the 1950s as a safer and more efficient alternative to acetylene gas, which is highly unstable and prone to explosion. What is Propane? Propane is a hydrocarbon gas that's commonly used as a fuel for heating and cooking. It's a byproduct of natural gas processing and oil refining, and it's stored in liquid form in pressurized cylinders. Propane has a lower boiling point than MAPP gas, which means it evaporates more quickly and produces a larger flame. Does MAPP Gas Burn Hotter than Propane? The short answer is yes, MAPP gas burns hotter than propane. The flame temperature of MAPP gas in air is around 3,730 degrees Fahrenheit, while propane burns at a temperature of about 3,600 degrees Fahrenheit. This means that MAPP gas can heat up metal faster and penetrate deeper than propane, making it a better choice for heavy-duty welding or brazing projects. However, it's important to note that MAPP gas is also more expensive and harder to find than propane. It's also more hazardous to use, as it produces more carbon monoxide and soot than propane. MAPP gas torches also require a special tip that's designed to handle the higher pressure and temperature of the gas, which adds to the cost and complexity of using it. When Should You Use MAPP Gas? MAPP gas is best used for applications that require high heat and fast heating times, such as brazing copper pipes or welding thick steel plates. It's also a good choice for outdoor projects where wind or cold temperatures can affect the flame of a propane torch. However, for most DIY or household tasks, propane is a more economical and practical choice. FAQs Q: Is MAPP gas safe to use? A: MAPP gas is generally safe to use if you follow the manufacturer's instructions and take proper safety precautions. However, it's important to wear protective gear, such as goggles and gloves, and to work in a well-ventilated area to avoid inhaling toxic fumes. Q: Can you use MAPP gas in a propane torch? A: No, MAPP gas requires a special torch tip that's designed to handle the higher pressure and temperature of the gas. Using MAPP gas in a propane torch can cause the tip to overheat and malfunction, leading to a fire or explosion. Q: Is MAPP gas worth the extra cost? A: It depends on your specific needs and budget. MAPP gas is more expensive than propane, but it burns hotter and faster, which can save you time and effort on heavy-duty projects. If you only need a torch for occasional household tasks, propane is a more economical choice.
