How to use the oil production wellhead device to play a greater effect?

The wellhead device is composed of steam Christmas tree and tubing head. A 7-inch bottom flange is connected to the lower part of the tapered seat tubing string, and the Christmas tree is connected to the upper part.

The wellhead device is a double-wing structure. This valve adopts the parallel gate structure commonly used in the world today. The valve body, valve cover, valve plate and valve stem are all made of materials with good high temperature resistance and creep resistance. The entire valve of the wellhead device can withstand a high temperature of 380. Under high temperature and high pressure, the valve will not be deformed when opening and closing. The non-metallic seal is made of high temperature resistant materials, and has good sealing performance under the wellhead 380.

A wellhead device and an oil production wellhead device include a tee, a gate, a pipe collar, a short joint, a flange and a polished rod sealer. The wellhead device is matched with the inner cone of the upper part of the lower flange to realize accurate positioning and centering. The well head is directly connected to the upper flange. The end face of the connection between the upper flange and the lower flange is provided with an annular groove, and the sealing steel ring is installed in the groove of the wellhead device. The entire wellhead device is simple in structure, light in weight, easy to manufacture, reliable in sealing, and convenient to use.
