Zhejiang Fengfeng Pipe Industry's electrofusion fittings achieve a zero-leakage, permanent joint through a meticulously controlled scientific process that creates a homogeneous, monolithic molecular bond between the fitting and the pipe. It is not merely a mechanical seal, but a fusion of materials into a single entity.

Step 1: Surface Preparation - Pipe end is scraped to remove oxidized surface layer. Step 2: Clamping & Alignment - Pipe and fitting are securely clamped in a straight, aligned position. Step 3: Initiation & Heating - Voltage is applied to the integrated resistance wire coil. Step 4: Melting & Interfusion - Molten material merges with internal pressure ensuring intimate contact. Step 5: Controlled Cooling - Joint cools naturally and uniformly under maintained restraint.

High-Density Polyethylene (HDPE) is a thermoplastic polymer made from petroleum. It is known for its high strength-to-density ratio, durability, resistance to impact, and ability to withstand various environmental conditions. The use of brand-new, virgin HDPE raw materials from traceable sources is fundamental for ultimate performance, safety, and commercial value.
