The GE (Hydril) brand is in existence under GE Oil & Gas. GE (Hydril) offers industry-leading designs for blowout prevention in all surface and subsea applications. Introduced in the 1930s, they were the first to develop the hydraulically operated BOP and annular BOP. GE (Hydril) maintains their status of being a top 3 blowout preventer manufacturer by persistently advancing the technology of a blowout preventer. GE (Hydril) offers a multitude of blowout preventer rams that protect personnel and equipment by reliably monitoring and controlling surges of oil, gas and drilling mud from a well bore.
GE (Hydril) Product Bulletins
The 'GK' annular preventer is designed for surface installations and is also used on offshore platforms and subsea. Standard operation requires both opening and closing pressure. Seal off is affected by hydraulic pressure applied to the closing chamber, which raises the piston, forcing the packing unit into a sealing engagement. Main features include:
- Only two moving parts (piston and packing unit) mean few areas are subjected to wear. The BOP is thus safer and more efficient requiring less maintenance and less downtime.
- Piston is designed to be well pressure assisted. This ensures a more positive seal off under kick conditions for a higher margin of safety.
- Field replaceable wear plate in the BOP head serves as an upper non-sealing wear surface for the movement of the packing unit, making field repair fast and economical.
- Piston stroke measurement provides indication of packing unit life without disassembly.
- Three choices of packing unit rubber compounds

1.6.1 Hydril 'GK' Stripping Operations
Hydril Gk 13 5 8 Operation Manual Pdf
During well control operations, drill pipe can be rotated and tool joints stripped through a closed packing unit, while maintaining a full seal on the pipe. Longest packing unit life is obtained by adjusting the closing chamber pressure just low enough to maintain a seal without any leakage as the tool joint passes through the packing unit. As a large diameter tool joint passes through the packing unit it expands. A responsive regulator valve must control the hydraulic surge pressure caused by packing unit expansion. Better control may be achieved with the addition of a surge absorber (accumulator) to the closing chamber. Pre-charge the accumulator to half the closing pressure required to effect seal off. Slow stripping speeds will give longest packing unit life.
