Mahanagar Gas Project Engineer Interview Questions, Process, and Tips

GTAW and TIG welding are the same process, with GTAW being the technical term and TIG being the commonly used name.

• GTAW stands for Gas Tungsten Arc Welding, while TIG stands for Tungsten Inert Gas welding.

• Both processes use a non-consumable tungsten electrode to create an arc for welding.

• GTAW and TIG welding are often used interchangeably, with TIG being the more commonly used term in industries.

• The main difference lie...read more

A Mahanagar gas network diagram with pressure variation needs to be drawn for the Project Engineer interview.

• The diagram should include all the pipelines and their respective pressure levels.

• The pressure variation should be shown using different colors or shades.

• The diagram should also include the location of gas stations and regulators.

• The pressure levels should be labeled and explained in a legend.

• The diagram should

Risk is the likelihood of harm or loss, while hazard is the potential source of harm or danger.

• Risk refers to the probability of an event occurring and the potential consequences of that event.

• Hazard is anything that has the potential to cause harm, such as chemicals, machinery, or natural disasters.

• Identifying and managing risks and hazards is important in ensuring safety and preventing accidents.

• Examples of hazards i...read more

Methane is a chemical compound with the molecular formula CH4.

• Methane is the simplest hydrocarbon.

• It is a colorless, odorless gas.

• It is highly flammable and burns with a blue flame.

• Methane is the main component of natural gas.

• It is produced naturally by anaerobic digestion of organic matter.

• Methane is used as a fuel for heating and cooking.

• It is also used as a feedstock for the production of chemicals such as methanol

The pipe diameter used in Mahanagar Gas varies depending on the specific project requirements.

• The pipe diameter used in Mahanagar Gas projects is determined based on factors such as gas flow rate, pressure, and distance.

• For high-pressure gas transmission pipelines, larger diameter pipes are typically used to minimize pressure drop.

• In distribution pipelines, smaller diameter pipes are used to supply gas to individual co...read more
