The PE Electrofusion Coupling (PN20) is a fundamental and critical fitting used to connect PE pipes of the same specification. This coupling is particularly suitable for main pipeline networks requiring high pressure-bearing capacity, such as municipal water supply and gas transmission. Its PN20 nominal pressure rating ensures long-term, safe operation under working pressures up to 2.0 MPa.

Product Features

Exceptional Durability

Prevents potential contamination of soil and groundwater by the conveyed medium.

High Pressure-Bearing Capacity

The PN20 pressure rating (equivalent to 2.0 MPa) makes it suitable for high-pressure main pipeline systems.

Environmentally Friendly Process

The electrofusion process produces no open flame, no smoke emissions, and has low energy consumption.

Premium Raw Material

The HDPE material itself is recyclable, making the entire system non-polluting to the environment.

Application Areas

Municipal Water Supply Pipelines

Used for connecting straight sections of water supply mains, ensuring water transmission safety.

Gas Transmission & Distribution Networks

Suitable for high-pressure main pipeline systems due to its PN20 pressure rating.

Industrial Piping Systems

Used in industrial pipelines conveying various chemical media.

FAQ

Q: What checks are essential before welding?

A: • Fitting Check: Use a multimeter to measure the fitting's resistance value; the deviation from the nominal value should not exceed ±10%. Also, check the appearance for any damage.
• Pipe Preparation: Ensure the pipe end is flat, square, and remove the oxide layer as required.
• Cleanliness: The fusion area must be absolutely clean and dry.

Q: What should be noted during the transportation and storage of fittings?

A: Avoid exposure to direct sunlight, rain, and keep away from heat sources. Do not stack them too high to prevent deformation under heavy weight. Pay special attention to protecting the terminal posts and identification markings from impact damage.

Q: How can I ensure the PE Electrofusion Coupling I purchase matches my pipes?

A: The key to matching lies in the Nominal Outside Diameter (dn) and the SDR (Standard Dimension Ratio) value. You must select a coupling with the exact same dn value and a matching SDR series as your pipe. For example, a dn110 SDR11 pipe must be paired with a dn110 SDR11 PE Electrofusion Coupling; otherwise, fusion failure will occur.

Q: Are the quotes inclusive of tax?

A: Our default quotes are ex-factory prices excluding tax. We can provide Special Value-Added Tax (VAT) invoices.
