Threaded Reducer Concentric
One end is the grooved connection, the other end is the threaded connection, Threaded reducer concentric coupling is specially used to connect different ends of two pipelines.
Install cost will be cheaper than grooved reducer concentric, But it will take more time, and pay more workers salary, to if consider all the cost, Threaded reducer concentric maybe not the most economic solution. But it is efficient to be suitable for different ends pipeline.
Jianzhi grooved fitting surface is smooth, and easy to install and assemble. The max working pressure can reach 2.5MPa.
