Oil (gas) production wellhead
Features:
The oil (gas) production wellhead is used mainly to suspend hanger and seal casing annulus. The product can be used as both production wellhead and fracturing wellhead for fracturing and acidification. The product consists of two parts such as tubing head and Christmas tree. The pressure grade of the product is 2000Psi~20000Psi(14MPa~140MPa) and its material grade AA~HH.
The Christmas tree can be divided into integral Christmas tree and split Christmas tree structurally. The tubing hanger has two main sealing modes such as rubber sealing and metal sealing and also two secondary sealing modes including rubber sealing and metal sealing.
