Electrofusion fittings allow for secondary welding. In the sales and application of polyethylene (PE) piping systems, approximately 15%–20% of sales revenue comes from fittings. PE piping system fittings are mainly divided into two types: heat fusion fittings and electrofusion fittings.
Due to price considerations, heat fusion fittings are used more extensively in engineering applications than electrofusion fittings. However, electrofusion fittings play a crucial and irreplaceable role in engineering and maintenance, especially during construction where they are less affected by external environmental and human factors, resulting in higher reliability and greater user appeal.
Electrofusion fittings are increasingly used, particularly in gas pipeline projects. Furthermore, due to the complex manufacturing technology, high cost, and relatively high selling price of electrofusion fittings, manufacturers enjoy higher profit margins, making them a hot investment area.
Additionally, because the base material of electrofusion fittings is PE, together with PE pipes, the PE piping system solves two major problems of traditional pipelines: corrosion and leakage at joints.
