I appeared for an interview in Sep 2024, where I was asked the following questions.
- Q1. What is the primary role of flanges in a piping system?
- Ans.
Flanges connect pipes, valves, and equipment, providing a secure, leak-proof joint for fluid transport in piping systems.
Flanges allow for easy assembly and disassembly of piping systems, facilitating maintenance and repairs.
They provide a strong, leak-proof connection that can withstand high pressure and temperature conditions.
Common types of flanges include weld neck, slip-on, and blind flanges, each serving specific...
- Q2. What is male and female fitting in installation process.
- Ans.
Male and female fittings are essential components in pipe installation, ensuring secure connections between pipes and fixtures.
Male fittings have external threads, allowing them to screw into female fittings.
Female fittings have internal threads, designed to receive male fittings.
Example: A male pipe fitting connects to a female valve for a secure seal.
Common types include male adapters, female adapters, and couplings.
- Q3. Difference between reducer and elbow.
- Ans.
Reducers change pipe diameter, while elbows change pipe direction, both essential in piping systems.
A reducer connects pipes of different diameters, e.g., from 4" to 2".
An elbow changes the direction of flow, typically at 90 or 45 degrees.
Reducers can be concentric or eccentric, affecting flow characteristics.
Elbows can be short or long radius, impacting space and flow resistance.
