Electrofusion
Electrofusion welding is a critical process in the construction of underground piping systems used for transporting water, gas, and other essential utilities. At Gebrema, we manufacture high-precision contact pins that play a small but crucial role in ensuring these welds are strong, consistent, and safe.
The Importance of Reliable Contact Pins
During the electrofusion process, electrical current is passed through metal coils embedded in plastic fittings, generating heat that melts and fuses the surrounding pipe material. The contact pins are the components that carry this current—and if they fail, the weld fails.
That’s why our customers depend on Gebrema to supply contact pins that are:
Dimensionally precise, ensuring a secure connection with the welding equipment
Mechanically stable, able to withstand the stresses of field installation
Surface-clean and consistent, for reliable current flow and even heat distribution
Each pin we produce must meet exacting tolerances and strict quality standards—because the integrity of the entire pipeline depends on it.
Used in Critical Infrastructure
The plastic piping systems joined by electrofusion welding are used across a wide range of applications, including:
Municipal water networks
Natural gas distribution
Sewage and stormwater systems
Industrial fluid handling
These networks are often buried underground, designed for decades of service, and must remain leak-proof and safe under pressure. Contact pins may seem minor, but they are essential to the proper functioning of this infrastructure.
