GX 13 5/8-10000PSI annular BOP packing unit NBR

The packing unit for the GX 13 5/8-10000PSI annular BOP

can hold full-rated working pressure after more closing cycles and stripping than any other unit available. The GX produces extra uptime from a significantly larger reservoir of engineered elastomer, and a BOP design that precisely controls the position of unique, f langed steel inserts. When the GX closes, the packing unit rubber drives the inserts inward, where they quickly reach a fixed position and form a steel ring that prevents the elastomer from extruding upward under wellbore pressure. After the ring is formed, feedable elastomer continues to flow inward around the inserts to create a seal on the drill string or open hole. Because the elastomer is primarily in compression, it resists tears, cuts and abrasions. When stripping, the steel inserts again remain fixed. As various diameters of pipe and tool joints pass through the closed unit, the elastomer flows in and out. Even at higher wellbore pressures, the GX packing unit maintains precise control of seal-off tightness to permit a slight passage of drilling fluid that provides lubrication, enhances pull-through forces and further prolongs packer life. No matter what type of severe service awaits your BOPs, expect more from the genuine Hydril Pressure Control GX Annular

The heart of every annular blowout preventer (ABOP) is its packing unit and Hydril Elastomers have been the market leader ever since we pioneered ABOPs over 70 years ago. But time didn‘t stand still; and neither did we. We proudly present our latest achievement, the introduction of our NBR-based ABOP packing unit.Part number:3112570-H1
