A type of mechanical seal is the cartridge seal which consists of a rotating and stationary face.
Cartridge seals are pre-assembled units that can be easily installed
They are commonly used in pumps and mixers
The rotating face is attached to the shaft while the stationary face is mounted in the seal housing
The seal faces are held together by a spring or other device to maintain contact and prevent leakage
SS 304 and SS 316 are both stainless steel alloys, but they differ in their composition and properties.
SS 304 contains 18% chromium and 8% nickel, while SS 316 contains 16% chromium, 10% nickel, and 2% molybdenum.
SS 316 has better corrosion resistance than SS 304, especially in environments with chlorides or acids.
SS 316 is more suitable for marine applications or those involving exposure to harsh chemicals.
SS 304 is g...

Reactors can be made of various materials depending on the application and requirements.
Common materials include stainless steel, carbon steel, and titanium.
Reactor linings can be made of glass, ceramic, or polymer materials.
Materials must be chosen based on factors such as temperature, pressure, and chemical compatibility.
Reactor materials must also be able to withstand corrosion and erosion over time.
Materials used i...
The question is unclear and lacks context.
Please provide more information about the reactor and the new shell.
What is the reason for removing the old shell?
What tools and equipment are required for the job?
What safety precautions need to be taken?
Are there any specific procedures or guidelines to follow?
Consult with experts and refer to manuals before attempting the task.
There are three types of vessels entry: Confined Space Entry, Hot Work Entry, and Cold Work Entry.
Confined Space Entry involves entering a space that is enclosed and has limited access points.
Hot Work Entry involves entering a space where welding, cutting, or other heat-producing activities are being performed.
Cold Work Entry involves entering a space where maintenance or repair work is being done that does not involve...
Blowers can be classified into centrifugal, positive displacement, and regenerative types. PM stands for Preventive Maintenance.
Centrifugal blowers use centrifugal force to increase air pressure
Positive displacement blowers use a mechanical means to trap and transport air
Regenerative blowers use a rotating impeller to create air flow
PM is a maintenance strategy that involves regular inspections and repairs to prevent e
Empelr and no oil are not common terms in maintenance engineering. Please provide more context.
Please provide more information or context for the terms empelr and no oil.
Without context, it is difficult to provide a meaningful answer.
It is possible that these terms are specific to a certain industry or company.
Please clarify the question so that a proper answer can be given.

I applied via Naukri.com and was interviewed before Feb 2022. There were 3 interview rounds.
LMTD stands for Logarithmic Mean Temperature Difference and is used to calculate the temperature difference in a heat exchanger.
LMTD is a method used to determine the temperature difference between two fluids in a heat exchanger
It takes into account the temperature difference at different points along the length of the heat exchanger
LMTD is used to calculate the heat transfer rate in a heat exchanger
It is calculated us...
The grade of materials used in storage tanks depends on the type of fluid being stored and the tank's operating conditions.
The material should be compatible with the stored fluid to prevent corrosion or contamination.
Common materials used for storage tanks include carbon steel, stainless steel, and aluminum.
The thickness of the material should be sufficient to withstand the pressure and temperature of the stored fluid.
...
Statutory compliance refers to the legal requirements that organizations must adhere to in order to operate within the law.
It includes following laws and regulations related to labor, environment, health and safety, taxation, and more
Non-compliance can result in penalties, fines, legal action, and damage to reputation
Examples of statutory compliance include filing tax returns, obtaining necessary licenses and permits, ...
Corrosion allowance is the additional thickness of material added to the original thickness of a metal to prevent corrosion.
It is a safety margin added to the thickness of metal to prevent corrosion
It is usually expressed in millimeters or inches
The amount of corrosion allowance depends on the type of metal, the environment it is exposed to, and the expected lifespan of the equipment
For example, a pipeline carrying cor...
Life of equipment refers to the duration of time that the equipment can function effectively and efficiently.
The life of equipment is determined by various factors such as usage, maintenance, and environmental conditions.
Regular maintenance and timely repairs can extend the life of equipment.
Equipment manufacturers provide an estimated lifespan for their products, but this can vary depending on usage and maintenance.
Fa...
I applied via Naukri.com and was interviewed in Jul 2021. There was 1 interview round.
Condensers are used in power plants to convert steam back into water for reuse in the boiler.
Condensers increase the efficiency of the power plant by allowing the reuse of water.
They reduce the amount of water needed for the power plant.
Condensers also help to maintain a vacuum in the turbine exhaust, which increases the power output.
Examples of condensers used in power plants include surface condensers and jet condens
CFM of blower can be calculated by multiplying the blower's airflow rate by the blower's operating speed.
Determine the airflow rate of the blower in cubic feet per minute (CFM)
Determine the operating speed of the blower in revolutions per minute (RPM)
Multiply the airflow rate by the operating speed to get the CFM of the blower
CFM = Airflow rate (CFM) x Operating speed (RPM)
