Oil Well API16A Annular BOP Tapered Packing Unit
FHZ18-70 Tapered Annular BOP Packing Unit 7 1/16" x 10000 psi
The packing units including tapered packing element and spherical packing element are the sealing component of the Annualr BOP. 7 1/16" x 10000 psi Tapered packing element is used for the FHZ18-70 Annular BOP. The packing unit is a special high performance product. The packing element is combined by the main body which is made up of the independent innovation rubber based polymer alloy material and the high strength metal frame, which conforms to the API 16A. The tapered packing unit is suitable for the drilling work on the oil field, which shares a high cost performance comparing to the other same type packing elements.
