National Oilwell Slips are designed for API-4 tapered bowls with an expanded back support area compared to competitor’s slips and provide a greater overall insert contact with tubulars. The 25° angle dovetail slot and insert design gives longer service life and mini- mizes insert loss. Configurations include drill collar, casing, small bowl slips Type B, and XL drill pipe slips. Casing slips for sizes 9⁵/8" - 20" for API-3 tapered bowls are also available. National Oilwell Safety Clamps are an essential tool for handling drill collars and any tubular goods with flush joints or low profile shoulders. Removable segments allow for adjustment of the National Oilwell Safety Clamp to handle pipe sizes from 1¹/8"   to 22".
