Suction piping of a pump is the piping system that brings fluid into the pump from the source.
Suction piping is designed to ensure a smooth flow of fluid into the pump without any air pockets or cavitation.
The piping should be sized appropriately to prevent excessive pressure drop and maintain efficient pump operation.
Proper alignment and support of the piping is crucial to prevent stress on the pump and ensure longevi...
Eccentric reducers are used in suction lines with flat side up to prevent air pockets and improve flow efficiency.
Eccentric reducers help in preventing air pockets from forming in the suction line
Having the flat side up ensures that any trapped air can easily escape
Improves flow efficiency by reducing turbulence and pressure drop
Commonly used in applications where smooth flow is critical, such as pump suction lines
Figure 8 is a type of knot commonly used in piping design to secure two ropes or cables together.
Figure 8 knot is also known as a stopper knot due to its ability to prevent ropes from slipping through holes or other openings.
It is easy to tie and untie, making it a popular choice for various applications in piping design.
The figure 8 knot is often used in rock climbing, sailing, and rescue operations for its reliabilit
Control station piping is essential for regulating and monitoring the flow of fluids in a system.
Control station piping connects various components such as valves, instruments, and equipment to control the flow of fluids.
Proper design of control station piping ensures efficient operation and safety of the system.
Consider factors like pressure, temperature, and material compatibility when designing control station pipin...
Suction piping of pump is crucial for efficient operation and performance.
Suction piping should be designed to minimize friction losses and ensure proper flow to the pump.
Proper sizing and layout of suction piping is essential to prevent cavitation and maintain pump efficiency.
Consider factors such as pipe diameter, length, bends, and fittings when designing suction piping.
Use smooth bore pipes, avoid sharp bends, and ...

I applied via LinkedIn and was interviewed in Apr 2023. There were 2 interview rounds.
Various pressure tests are conducted on valves including hydrostatic test, pneumatic test, and cryogenic test.
Hydrostatic test is conducted by filling the valve with water and pressurizing it to a specified pressure to check for leaks.
Pneumatic test involves using air or nitrogen to pressurize the valve and check for leaks or defects.
Cryogenic test is performed at low temperatures to ensure the valve can withstand extr...
Safety considerations in designing piping systems are crucial for preventing accidents and ensuring the integrity of the system.
Ensuring proper material selection to withstand the intended pressure and temperature conditions
Implementing proper support and restraint systems to prevent excessive stress and vibration
Incorporating adequate access points for maintenance and inspection
Following relevant codes and standards s...

Expansion stress formula calculates the stress caused by thermal expansion or contraction.
Expansion stress formula is given by: ΔL/L = αΔT, where ΔL is the change in length, L is the original length, α is the coefficient of thermal expansion, and ΔT is the change in temperature.
The formula can be used to calculate the stress caused by thermal expansion or contraction in piping systems.
The formula assumes that the mater...
Sustain stress formula calculates the maximum allowable stress for a given material under sustained loading.
Sustain stress formula is used in piping stress analysis to determine the maximum allowable stress for a given material under sustained loading.
The formula takes into account the material's yield strength, ultimate tensile strength, and safety factor.
Sustain stress formula is expressed as S = (Sy/FS) + (Su/FS) * ...
