Electrofusion pipe fittings include sleeves, saddles, reducers, tees and elbows, etc. The key to electrofusion connection technology is to select pipe fittings that meet the standard. The gap between the pipe and the pipe fittings is appropriate, and the connections of different specifications and sizes have their own better gap values; the outer surface of the pipe must ensure the process requirements when scraping the oxide scale before connecting. The better interval value is to ensure that when the temperature of the connection interface reaches the specified value, the welding pressure established by the expansion of the material is balanced throughout the welding interface, so that the molecular chain is fully and uniformly diffused and entangled.
When operating a fully automatic electrofusion welding machine, you must pay attention to poor operations, which will directly affect the quality of welding. When performing electrofusion connection, pipe fittings assembly, positioning, pipe or socket pipe surface oxide layer treatment and other operations do not meet the requirements of the specification. The quality of the interface has an adverse effect and leads to welding failure.
