Forged fracturing head
Forged fracturing head is a special accessory for petrochemical industry. The lowest part of the wellhead--casing head that is almost always connected to the surface casing string, and provides a means of suspending and packing off the next casing string. Providing attachment to the surface casing string through the type of bottom connection (Slip-on-weld, threaded, Sliploc), the casing head is typically qualified to withstand up to 10,000 psi working pressure. It suspends the casing and packs off the next casing string while providing annular outlets, as well as supporting the BOP while drilling the remaining stages.
