The double-cylinder protector is mainly used for oil and gas well fracturing (acidification) to protect the lower pressure level of the tree wellhead device for safe operation under high pressure. It has the characteristics of safety, reliability, simple structure and convenient operation.
Using the fracturing (acidification) process of the wellhead protector, the general wellhead tree is all within a low pressure of 35 MPa. The tree must be protected for special operating environments such as high pressure fracturing (acidification). It mainly feeds the central pipe and the sealing packing mechanism into the double male short section inside the oil pipe cross, and seals it to ensure that the tree is isolated from the working environment.
The basic structure of the double cylinder protector mainly consists of: upper lifting lug, middle two cylinder pusher, hydraulic cylinder fixing bracket, lower connecting flange, center tube and sealing packing
