Acetylene Market Size

Acetylene Market size was over USD 6.51 billion in 2024 and is projected to reach USD 10.65 billion by the end of 2037, growing at around 3.9% CAGR during the forecast period i.e., between 2025-2037. In the year 2025, the industry size of acetylene is assessed at USD 6.71 billion. The growth of the market can be attributed to the surge in the chemical sector by the production of various chemicals, along with the rise in the welding sector with the increasing use of acetylene for metalwork in the welding industry. For instance, around USD 4.9 trillion in revenue was generated by the chemical sector worldwide in 2021. Further, the escalating use of acetylene as a fuel in oxyacetylene metal cutting, and its increasing application in various end-use industries are some further factors that are anticipated to drive the growth of the global acetylene market over the forecast period.

In addition to these, factors that are believed to fuel the market growth of acetylene include its rising application in gas welding steel as of its extreme temperature as compared to other compounds such as propane. For instance, when propane is burned in oxygen, it creates a flame temperature of around 2800°C. But together with oxygen, acetylene creates a higher flame temperature of nearly 3300°C. As a result of its high combustion temperature, acetylene is an extremely appropriate choice for gas welding steel. In addition to this, the soaring investments in the chemical industry are also a major factor that is projected to propel the growth of the market over the forecast period. Additionally, worldwide proliferating applications of metalworking in various sectors, along with the radically increasing construction activities throughout the world are also predicted to present the potential for market expansion over the projected period.
