Sample interview questions: Are you familiar with different types of pipe jointing methods (e.g., soldering, welding)?
Sample answer:
- Soldering:
- Widely used for joining copper pipes
- Requires a heat source and a soldering iron
- A flux agent is used to clean surfaces and promote a strong bond
-
The most common type of solder used is a tin-lead alloy
-
Welding:
- A permanent joint created by melting and fusing the base metals
- Can be used for various metals, including steel, cast iron, and copper
-
High-temperature welding methods require specialized training and equipment
-
Threaded Joints:
- A mechanical joint created using threaded fittings and couplings
- Requires accurate cutting and threading of pipes using a threading machine
-
Thread sealants are used to prevent leaks
-
Compression Joints:
- A type of mechanical joint commonly used for connecting copper or plastic pipes
- Utilizes a compression ring and a nut to create a seal
-
Provides a quick and easy method for joining pipes without welding or soldering
-
Push-Fit Fittings:
- A relatively newer method for joining pipes, primarily used for plastic pipes… Read full answer
