Drilling Swivel

Swivel is a device joining two parts so that one or both can pivot freely. Drilling Swivel is one of the main components that make a Rotary System superior to the ones that don’t have one. The swivel is the most important part of the entire rotary drilling system. The swivel is supposed to transfer the water at very high speed through the stem of the drill all the way leading to the bit. This helps both in cooling and lubricating the bit while the drilling process continues through the flushing and forcing of the cuttings straight away out of the borehole. Swivel has two categories, common swivel and double duty swivel. Double duty swivels are common swivels combined with spinners. Landa provides swivels meeting with API Spec 8A.

It consists of two main parts:
(1) non-rotating –cast steel body with load carrying bails, pins and roller bearings
(2) rotating –"T" mandrel and wash pipe.
