This is a type of quick couplings.It includes: welded, ring style and flare.Quick couplings can be divided into: air with quick couplings, quick couplings with oxy-fuel gas, gas liquids share quick couplings, hydraulic quick couplings, quick couplings with an inert gas, cooling water temperature of the oil with quick couplings, semiconductors, connectors.
Quick couplings, a pipeline can be achieved without tools connected or disconnected joints. Transition pipe joints,...
