Ques:- Which type of valve is used in steam lines?
Asked In :-
Right Answer:
The most commonly used valves in steam lines are:
1. Globe Valve – for throttling and controlling steam flow 2. Gate Valve – for full open or close (isolation) 3. Safety Valve – to release excess pressure 4. Ball Valve – for quick shut-off (less common in high-pressure steam) 5. Steam Trap – removes condensate without letting steam escape
1. Welding current
2. Voltage
3. Travel speed
4. Electrode type and diameter
5. Shielding gas flow rate
6. Arc length
7. Heat input
8. Joint design and preparation
Right Answer: A diesel engine is an internal combustion engine that uses diesel fuel to power its operation. It ignites the fuel through compression rather than using a spark plug, making it more efficient and suitable for heavy-duty applications.
Right Answer: PFMEA stands for Process Failure Mode and Effects Analysis. It is a systematic method used to identify potential failures in a manufacturing or business process, assess their impact, and prioritize actions to mitigate risks.
Right Answer: SS stands for Stainless Steel. The main difference between SS304 and SS316 is that SS316 contains molybdenum, which provides better corrosion resistance, especially against chlorides and marine environments, while SS304 is more susceptible to corrosion in such conditions.
Right Answer: DGS stands for "Distributed Generation System," which refers to small-scale power generation technologies that operate close to the point of use, often utilizing renewable energy sources.
Right Answer: To reduce power consumption, you can implement the following strategies:
1. Use energy-efficient appliances and equipment.
2. Optimize production processes to minimize energy use.
3. Implement regular maintenance to ensure equipment operates efficiently.
4. Utilize renewable energy sources where possible.
5. Educate employees on energy-saving practices.
6. Monitor and analyze energy usage to identify areas for improvement.
7. Install energy management systems to track and control consumption.

Right Answer: Hydroforming is a manufacturing process that uses high-pressure fluid to shape metal into desired forms, allowing for the creation of complex shapes with a smooth surface finish.
Right Answer: As a Quality Engineer in the mechanical field, my role and responsibility include ensuring that products meet quality standards, conducting tests and inspections, analyzing data to identify defects, collaborating with design and manufacturing teams to improve processes, and implementing quality control measures to enhance product reliability and performance.
Right Answer: A transformer is an electrical device that transfers electrical energy between two or more circuits through electromagnetic induction, typically used to increase or decrease voltage levels in power systems.
Right Answer: 1. Use sharper cutting tools.
2. Optimize cutting speed and feed rate.
3. Select appropriate cutting fluid or coolant.
4. Use a suitable tool geometry.
5. Reduce tool wear through proper maintenance.
6. Implement vibration control techniques.
7. Minimize cutting depth when possible.
Right Answer: Cutting clearance is the space or gap between the cutting tool and the workpiece that allows for the removal of material without causing damage to the tool or the part being machined.
