DU Slips

The Ramey Martin DU Rotary Slips are designed for long trouble-free service.  They are made of alloy steel and heat-treated for strength and resistance to wear.  The slip is machined for use in API tapered bowls with a 4″ taper per foot(TPF) on the diameter.  The DU Regular has a 12″ gripping service for use in shallow wells while the DU Long has a 16″ gripping surface for deeper wells and heavier drill strings.  All Ramey Martin DU Rotary Slips are load rated and manufactured to meet API 7K requirements.
