A fused connecting pipe can be considered as a continuous pipe without a joint. On the other hand, gasket joints are a source of leakage and water loss in many water systems. If the gasket is not properly installed, if the gasket does not properly lubricate the gasket, if the gasket is not properly lubricated, if a negative pressure (vacuum) occurs in the pipe, if ground movement or bottom groove consolidation occurs, if a significant thermal change occurs, or if the gasket burns out due to surge pressure, a leak may occur. So weld joints are generally considered to be superior to gasket joints to prevent leakage.
