This product is a key connecting component designed for High-Density Polyethylene (HDPE) pipeline systems with an outer diameter of 250 mm. These HDPE electrofusion fittings retain the excellent corrosion resistance, abrasion resistance, and stress crack resistance of HDPE pipes, making them widely applicable for large-diameter pipeline connections in municipal water supply and drainage, gas distribution, and industrial fluid handling.

To ensure quality, every DN250 electrofusion fitting is manufactured using PE100-grade raw material. The production process ensures that the internal resistance wires are arranged uniformly and consistently. Each fitting is labeled with a clear barcode containing fusion parameters along with written instructions.

Our Commitment: Quality as the Foundation of Electrofusion Fittings

Ambient Temperature Burst Pressure Test
Elevated Temperature Sustained Hydraulic Strength Test
Resistance Value Consistency Check and Dimensional/Visual Inspection

These tests guarantee that every fitting leaving our factory meets the highest standards of safety and reliability.

Before welding, follow these steps:
1. Clean the pipe end.
2. Scrape off the oxide layer.
3. Ensure correct alignment and pipe gap.

The welding machine can then automatically read the barcode to complete the fusion process. Each fitting includes an inspection hole that allows visual confirmation of the fusion during welding, providing assurance of quality and safety for large-scale projects.

FAQ

Q: Can you provide samples for testing?

A: Yes, we can provide samples for quality verification and installation testing.

Q: Are the samples free of charge?

A: The samples are free, but customers need to cover the courier costs.

Q: What should I do if the fitting and pipe do not fit tightly during installation?

A: First, check whether the pipe and fitting specifications match. If they do, the issue may be an out-of-round pipe end or debris. Use a pipe re-rounder to correct the pipe end and clean it with tools such as sandpaper.

Q: How should electrofusion fittings be installed in low-temperature winter conditions?

A: Preheat the pipes and fittings to above 5°C, extend the fusion time appropriately, and apply insulation measures after welding to prevent rapid cooling from affecting the joint quality. These HDPE electrofusion fittings maintain reliability even under challenging conditions.
