GCU-BT Cementing head single plug for drill pipes
GCU-BT Cementing head single plug for drill pipes is designed for connection of the cementing unit pressure manifold to the drilling pipes used for descending secret columns (liners) into a well. In terms of the structure, GCU-BT heads are similar to GCU heads with the attached collector and modified according to drill pipe lock dimensions.
