Q1: What are the advantages of PEX expansion fittings?
A1: - High safety: Utilizing the thermosetting characteristics, toughness and memory function of the pipe, the connection is achieved by directly compressing the pipe, without the hidden dangers of aging,
breakage and leakage of the rubber ring, which improves the safety of the pipe system.
- Firm connection: Each connection is tightly connected, and the pipe is pressed into the ribs in the pipe fittings. After the test, the pipe will not fall off even if it is stretched to break, ensuring the firmness of the connection.
- Reusable: The pipe fittings can be disassembled and reused, without wasting pipe fittings and reducing the cost of use.
- Convenient installation: It can be operated with water and can be installed even when the pipe valve is not tightly closed.
Q2: What pipe systems are PEX expansion fittings used in?
A2: PEX expansion fittings are widely used in residential and commercial hot and cold water, drinking water distribution systems, and sealed central heating systems, including underfloor heating systems.
Q3: How to connect PEX expansion fittings?
A3: 1. Preparation: Make sure the ends of the PEX pipe and fittings are smooth and have no obvious damage or dirt.
2. Choose fittings:Choose appropriate PEX expansion fittings according to the pipe diameter.
3. Insert the pipe: Insert the PEX pipe end into thepipe fitting to be connected, and make sure the insertion depth meets the manufacturer's regulations to ensure the reliability of the connection.
4. Perform expansion: Use a special PEX expansion tool to expand the connection point so that the pipe fitting and the PEX pipe are tightly combined.
5. Check the connection: After the expansion is completed, perform a visual inspection of the connection point to ensure that the connection is firm and the PEX pipe is not loose.
6. Pressure test: After the installation is completed, perform a system pressure test to ensure that there will be no problems with the connection point under normal working pressure.
