In the light of the problems with imported offshore wellhead, such as being bulky and expensive and being inconvenient to mount and maintain, Model HKY65―21 offshore wellhead is developed. This wellhead consists of tubing head assembly, PHK plate gate valve, safety valve, stop valve, clamp, small four-way connection and choke, and it is small-sized, light-weighted, high-strength, corrosion- and abrasion-resistant, reliably sealed and convenient to mount and maintain. Application shows that the wellhead can satisfy the requirements of offshore production with good performance.
