Oil Turbing Hanger Manufacture

Oil Tubing Hanger :

A tubing hanger suspension assembly for an oil and gas well completion system and a method of installing same.

it is a device that supports tubing string and seals the annular space between tubing and casing. The sealing method of the tubing hanger is that the tubing hanger and the tubing are connected by using the gravity of the tubing to sit in the tubing hanging big four-way cone to seal, which is easy to operate, fast and safe to change wellheads, so it is a commonly used method for medium and deep wells and conventional wells. .

We produce and Supply oil tube hanger according to clients drawing, our mateiral main are Inconel 718,Inconel 725,Monel 400 and Inconel x750, They Made of foriging bar with heattreatment condition, Dimension and tolearnace as per clients drawing.

The tubing hanger is located in the tubing head.

 ♦ Tubing head structure The tubing head is usually a big four-way with flanges at both ends. It is installed on the upper flange of the casing head to hang the tubing string and seal the annular space between the tubing string and the oil layer casing. It consists of tubing head and tubing hanger.     ♦ The function of the tubing head 1) Suspend the tubing string in the well; 2) Seal the annular space of the tubing and casing; 3) Provide transition for connecting casing head and Christmas tree; 4) Through the two side ports on the tubing head cross-body, complete casing injection and well washing operations

                                                     ♦  ♦  ♦  Corrosion Resistant Tubing Hanger Materials Features:   ♦  ♦  ♦                                          

 ♦ 17-7PH (GH631, 0Cr17Ni7Al)

17-7PH similar corrosion resistance to 304 stainless steel, which can be precipitated by heat treatment and precipitation hardening. It has high tensile and yield strength. The fatigue performance is better than 304 stainless steel and 65Mn carbon steel. It also has good elasticity under ℃ environment.

 ♦ 15-7Mo (GH632, 0Cr15Ni7Mo2Al)

    15-7MoHas similar corrosion resistance to 316 stainless steel. It can be precipitated by heat treatment and precipitation hardening. It has high tensile and yield strength, and its fatigue performance is better than 316 stainless steel and 65Mn carbon steel. It also has good elasticity under ℃ environment.

 ♦ Inconel X-750 (GH4145)

   Inconel X-750  is a nickel-based precipitation hardening deformation superalloy. It mainly uses r'phase as the aging precipitation hardening phase. The recommended temperature is below 540℃. The alloy has certain corrosion resistance and oxidation resistance, and has certain low temperature performance.

 ♦  Inconel 718 (GH4169)

Inconel 718  is a nickel-based precipitation hardening deformation superalloy. The recommended temperature range is -253--600℃. The alloy has high strength below 600°C, has good fatigue resistance, radiation resistance, oxidation resistance and corrosion resistance, as well as good processing performance and long-term structural stability.
