1.Material:alloy steel
2,Grade: N80/K55/P110/L80
3.Thread: BTC/LTC/STC

1. Description:

   Float collar's installed on the casing and up the float shoe. It also like float shoe to provide buoyancy to the casing 

string while it lowered, reducing the load on the Drilling rig. A build in check valve provides buoyancy to the casing 

string also prevents cement from re-entering the casing after it is displaced. It's a receptacle to cement plug.

2. Features:

1.)  All inner parts are made of easily drillable aluminum alloy.

2.) The device can be connected directly to same type casing.

3.)  Reliable back-pressure leakproof structure, enable grout or slurry flow with less resistance.

4.)  Valve seat and valve disk can effectively prevent grout from flowing back.

5.)  Non-rotating landing plate is available on request.

6.)  Either PDC or rock bit drillable.

oil (gas) well head device and valve

wellhead Device mainly composed of casing head and tubing head. Tubing head is an important part to connect tube and casing head

The Christmas tree is the assembly of the valve and the accessories, which is used for the fluid control of the oil/gas well

The Christmas tree is the assembly of the valve and the accessories, which is used for the fluid control of the oil/gas well, and supplying the inlet for the tubing string. The Christmas tree refers to all the devices on the tubing head and the flange. The Christmas tree could be assembled differently so as to meet the different requirements. The Christmas tree could be used for oil exploration, gas exploration, water adding, compression fracture, acidification, etc. The different Christmas trees are with the different pressure grades.
The Christmas tree and the tubing heads are mainly used for gas exploration and adding. Because the natural gas is with the low relative density and adding pressure, while the wellhead is with the high pressure and flow rate, it would be easy to leak. Sometimes, there’s H2S, CO2 and other corrosive medium in the natural gas. It would have the more strict requirements on the sealing capacity and the sealing materials of the Christmas tree. Thus, the tube and the sleeve should be with double valves. The valves should be forged by the best-quality steel for the high-pressure or extra-high-pressure gas well.

 


The main bearing pieces of the Christmas tree and the tubing heads are forged or cast, with the advantages of high bearing capacity, safety, reliability, etc.
