Top 10 Questions for Piper Installer Interview

1. What is the purpose of using a flux when soldering copper pipes?

The purpose of using a flux when soldering copper pipes is to remove oxides from the surface of the metal, allowing the solder to flow more easily and create a stronger bond.

2. What is the difference between a slip joint and a sweat joint?

• Slip joint is a type of pipe joint that is made by inserting one pipe into another and securing it with a clamp. It is a quick and easy way to connect pipes, but it is not as strong as a sweat joint.
• Sweat joint is a type of pipe joint that is made by heating the ends of the pipes and then soldering them together. It is a stronger joint than a slip joint, but it takes longer to make.

3. How do you determine the correct size of pipe for a given application?

The correct size of pipe for a given application depends on the flow rate of the fluid, the pressure of the fluid, and the length of the pipe. There are several methods for determining the correct pipe size, including using a pipe sizing chart or using a pipe sizing calculator.

4. What are the different types of pipe fittings and when should each type be used?

• Elbows are used to change the direction of a pipe.
• Tees are used to connect three pipes together.
• Crosses are used to connect four pipes together.
• Reducers are used to connect pipes of different sizes.
• Unions are used to connect two pipes together in a way that allows them to be easily disconnected.

5. What are the different types of pipe materials and what are the advantages and disadvantages of each?

• Copper is a popular choice for plumbing pipes because it is durable, corrosion-resistant, and easy to work with. It is also relatively expensive.
• PVC is a type of plastic pipe that is lightweight, inexpensive, and easy to install. It is not as durable as copper, but it is a good choice for many applications.

• Clogs can be caused by a buildup of debris or sediment in the pipes. They can be cleared by using a drain snake or a chemical drain cleaner.
• Frozen pipes can occur in cold weather when the water in the pipes freezes. They can be thawed by using a heat gun or by running hot water over them.

8. What are some of the latest trends in piping technology?

• The use of PEX tubing is becoming increasingly popular because it is flexible, durable, and easy to install.
• Smart piping systems are being developed that can monitor the flow of water and detect leaks.
• The use of 3D printing is being used to create custom-fit piping components.
