Sleeve head:
The casing head is a component that connects the casing and various wellhead devices. Used to support the gravity of technical casing and oil reservoir casing, seal the annular space between each layer of casing, and install blowout preventers. The upper wellhead devices such as the tubing head and Christmas tree provide transitional connections, and through the two side ports on the casing head body, operations such as adding cement, monitoring well sinking, and injecting balancing fluid can be carried out.
The casing head produced by our company has a standard structure, and our company's casing hanger is installed inside its shell. Different sizes and specifications of casing hangers can be selected according to the casing program and changes in wellhead conditions. The upper part of this body is connected by API 6A standard flange.
Threaded or welded bottom connection sleeve head
The optional options for the casing head are:
The lower part of the casing head can be connected with API standard round threaded casing female thread connection or API standard trapezoidal casing threaded female thread connection, or it can be a plug-in welded casing connection or a slip type connection. We can provide a welded support chassis. There are two types of side outlets: pipeline thread type and wire planting type. The side mouth of the wire planting type is processed with female threads for R1-1/2 "valve changers.
