Sample interview questions: Can you explain the different types of pipe joints you are familiar with?
Sample answer:
Types of Pipe Joints:
1. Threaded Joints:
– Male (NIPPLE) and female (COUPLING) threaded components
– Require sealant (e.g., Teflon tape) for sealing
– Strong, versatile, and can withstand high pressure
2. Soldered Joints:
– Copper pipes and fittings joined using lead-free solder
– High strength, corrosion resistance, and thermal stability
– Suitable for water, gas, and refrigerant lines
3. Brazed Joints:
– Similar to soldered joints, but utilize a higher-temperature brazing alloy
– Can withstand extreme temperatures and corrosive environments
– Commonly used in refrigeration and industrial applications
4. Compression Joints:
– Utilize a compression ring to seal the pipe inside a fitting
– Do not require threading or soldering
– Suitable for temporary or quick repairs
5. Flanged Joints:
– Consist of two bolted flanges connected by a gasket
– Allow for easy disassembly and equipment isolation
– Designed f… Read full answer
