The function of casing head 1. Hang part or all of the weight of each layer of casing except the surface casing through the hanger; 2. Form a pressure seal between the inner and outer casing strings; 3. Connect wellhead devices such as blowout preventers; 4. Provide an outlet to release the pressure that may accumulate between the two sets of pipe strings; 5. In an emergency, fluid, such as well killing fluid or fire extinguishing agent, can be pumped into the well through the side hole of the casing head;     Casing head structural characteristics and sealing principle The casing head is mainly composed of bottom casing head, casing hanger, casing head spool, valve and other components. The casing head seal consists of the casing head body, BT-shaped rubber sealing ring, casing hanger, dovetail-shaped rubber sealing ring, top wire V-shaped sealing ring, and sealing gasket ring. ​

The function of the wellhead equipment is to suspend the oil pipe and seal the annular space of the oil casing. The most basic parts of the wellhead equipment are the tubing head (casing tee or cross), tubing tee and sealing box. In addition, it also consists of production valves, back pressure valves, vent sampling valves, oil casing connection valves, etc., and is equipped with oil pipe and casing pressure gauges to observe oil casing pressure. 1. The Xmas tree Wellhead device, commonly known as "Xmas tree", is one of the most important and common equipment for oil, gas and water wells, and is the main equipment for controlling and regulating oil well production. Its main functions are: (1) The weight of all the tubing strings in the suspended tubing and supporting well; (2) Seal the annular space between oil and casing to control casing gas; (3) Control and regulate oil well production; (4) Daily management such as recording oil, sleeve pressure data, testing, wax removal, etc.; (5) Ensure the smooth progress of underground operations such as well cleaning, sand flushing, acidification, and fracturing.

The Thread Protectors are designed to provide protection to the connections during handing transportation,and to prevent debris from entering the threads and tube body. The threads are made in such a manner that they cover all the threads of the connections and prevent the thread protector from stripping or vibrating loose. We can produce premium thread protector and customize. NC23 NC26 NC31 NC35 NC38 NC40 NC44 NC46 NC50 NC56 NC61 NC70 NC77 NC38 DSTJ NC50 DSTJ 2 3/8REG 2 7/8REG
