Application Scope: Used in acidizing fracturing, sand fracturing, and hydraulic fracturing pipelines during well completion operations. It enables quick connection between fracturing wellheads and distribution skids, as well as between fracturing trucks and high-low pressure manifolds, and is designed to convey water-based, oil-based, foam, and acid-based fracturing fluids under high pressure.
