This product is used within the flow path of medium-diameter pipes. It is designed for scenarios that require a flanged connection, where butt fusion is not possible, or for connecting to equipment, specifically for interface sections of 160mm diameter PE water pipes. It can withstand pressure and is commonly used in applications such as municipal main lines, industrial cooling water lines, and seawater transport, offering exceptional sealing and structural strength. The product is integrally molded from high-quality PE and features a densely wound internal heating coil, ensuring uniform internal heating. This enables effective heating and fusion of large-diameter circumferential openings. The machined flange face provides a tighter seal, and the accurately positioned flange bolt holes offer wide applicability for connecting to various equipment and accessories. It eliminates the need for cumbersome processes like main pipe interface welding or coupling sleeves, proving to be superior and more practical than traditional grooved quick clamps. It holds an indispensable position in medium-sized pipeline projects. This product is one of the company's main offerings, reflecting its strength and expertise.

FAQ

Q: I'm unsure which specification of electrofusion fitting to choose.

A: Measure the outer diameter and wall thickness of your pipe in advance. Understand the system's working pressure and temperature. Contact your supplier or consult the relevant product parameter manual to confirm the required fitting model (Nominal Diameter, Nominal Pressure).

Q: Are electrofusion fittings from different brands interchangeable?

A: For most fittings complying with national standards, the main dimensional specifications are generally consistent. However, some details, like the distance and depth of the heating wires, may differ. Whenever possible, choose the same brand for both pipe and fitting, or select fittings that have been tested for compatibility with your pipe brand.

Q: If a fitting suddenly cracks during use, what is the emergency procedure?

A: Immediately shut off the upstream valve using a leak clamp or other tool to stop the water flow. Temporarily seal the crack with a specialized leak repair clamp to prevent major water leakage. After draining the water, cut out the damaged fitting and replace it with a new one using electrofusion welding. Before returning to service, pressure test the repaired pipeline section to ensure it is qualified.
