About the Oilfield Equipment in the Catalogue

This section includes a Christmas tree (wellhead equipment). Per GOST 13846-89, a wellhead Christmas tree consists of a tree and a tubing head assembly. It is used to seal the wellhead, suspend the tubing string, direct production into the flow line, and regulate and monitor the well’s operating mode.

The standard specifies series of nominal bore sizes of the main run (50, 65, 80, 100, 150 mm) and working pressures; for a 65 mm main run, these are 14, 21, 35, 70 and 105 MPa. The standard designation contains the number of the standard layout, the bore sizes of the main run and side outlets, and the working pressure. Corrosion-resistant versions K1–K3 are also provided for, depending on the CO₂ and H₂S content.

For the item in stock, the inventory records state DN 65 and PN 350 without a unit of measurement. If this is kgf/cm², the value is close to the 35 MPa rating, but this requires confirmation. The standard layout, scope of supply, type of shut-off devices and corrosion-resistant version are to be confirmed from the nameplate and data sheet.

In your request, state the working pressure and bore sizes required for your well, the composition of the production (presence of CO₂ and H₂S) and the required scope of supply.
