Product Introduction
As one of the important components in drilling equipment, the casing head cross provides a hanger bearing function for secondary drilling. The top cross of the tubing head installed on the surface wellhead device installs the tubing head after the final casing head installation to provide a bearing shoulder to support the tubing and provide sealing holes for the tubing hanger or production casing/tubing annular space seal. After completion of the well, the Christmas tree is installed on the top of the tubing head through the tubing head conversion connection device

Sealing Performance Guarantee
1.FLS valve seat and valve body sealing
Metal seal between valve seat and valve body.
2.Valve seat and gate sealing
There is a metal seal between the valve seat and the gate.The surface of the gate and valve seat is plasma sprayed with nickel based alloy or sprayed with tungsten carbide hardening treatment, which has good wear and corrosion resistance. The flatness of the sealing surface is ≤ 0.006mm, the parallelism is ≤ 0.01mm, and the surface roughness of the sealing surface is less than 0.4 after precision grinding, grinding, and polishing treatment μ m. Ensure the sealing of the gate valve seat.
3.FLS valve seat seal
Combined sealing component, the sealing material adopts imported sealing components or imported rubber: PEEK+EIGILOY corrosion-resistant alloy spring, ensuring the sealing performance of the valve seat.
4.Valve stem seal
Combined sealing component, the sealing material adopts imported sealing components or imported rubber: PTFE+EIGILOY corrosion-resistant alloy spring, ensuring the sealing performance of the valve stem.
5.Sealing performance guarantee of oil pipe head and casing head
The hanger and casing sealing of 105MPa and above oil pipe heads and casing heads adopt metal sealing methods to ensure the sealing of the product.
