Adapter Coupling

In drilling operations, the adapter coupling or "underlayer" is a component placed at the bottom of the drilling hole. Its primary functions are:

1. Base Stabilization: The adapter coupling stabilizes the base of the drilling hole and prevents it from collapsing. This preserves the structural integrity of the hole during drilling operations.

2. Equipment Protection: It protects drilling equipment from damage at the base of the drilling hole. In scenarios involving high pressure and heavy equipment, the adapter coupling safeguards equipment, extending its lifespan.

3. Soil Protection: The adapter coupling prevents further degradation of soft or collapsing soils at the base of the drilling hole, thereby enhancing the efficiency of the drilling process and improving sampling procedures.

4. Water and Sediment Management: It reduces the ingress of water and sediments into the base of the drilling hole, allowing for a more controlled and orderly drilling process.

In summary, the under armor serves to protect and stabilize the base of the drilling hole, aiding in the safe and effective execution of drilling operations.
