NANOCUT: High Therm Indane Cutting Gas

Conventionally metal cutting application involves usage of Oxy Acetylene mixture which has higher degree of hazard potential due to high shock sensitivity and very large flammability range. The method of using oxy-acetylene gas for metal cutting applications is fraught with potential hazard of explosion during usage as well as storage and hence discouraged worldwide despite of its high flame temperature and calorific value. The issue of high cost and hazards associated with acetylene calls for an alternative which is safer, cheaper, and easily available. This has prompted the usage of Liquefied Petroleum Gases (LPG) for metal cutting applications. However, the lower flame temperature of LPG has been an adverse aspect, which limits the use of LPG in high temperature applications such as metal cutting.

IndianOil, the top energy provider in India, has been working on the ways and means of enhancing the performance of LPG for high flame temperature applications. Our new product "Indane NANOCUT" is additized LPG for high temperature Industrial applications which is based on a proprietary additive formulation innovated at Indian Oil R&D Centre Faridabad. The indigenously developed additive enhances the efficiency of LPG as cutting gas in terms of high flame temperature, heat through put, low oxygen consumption, reduced cylinder inventory, thereby leading to better economy to the user of "Indane NANOCUT".

Indane Nanocut

Indane Nanocut, an innovative product developed by IndianOil R&D, has bagged yet another prestigious innovation award today under the category of Breakthrough Product – Innovation in R&D and AI in a nationwide Innovation Contest held by All India Management Association (AIMA). Indane Nanocut (an LPG variant enriched with proprietary additive formulation) is a safe and efficient alternative to the hazardous oxy-acetylene gas used for metal-cutting and other high-temperature applications.

Handling & Protection:
Personal protective equipment (PPE) is critical in a fabricating shop involving in metal cutting operations for several reasons. The Occupational Safety is of immense importance for the industrial sector. Hazards exist in every workplace in many different forms and controlling a hazard at its source is the best way to protect employees. Employers must provide personal protective equipment (PPE) to their employees and ensure its use. Examples of PPE but not limited to items as gloves, foot and eye protection, protective hearing devices (earplugs, muffs) hard hats, and full body suits.
