Wellheads & Christmas trees

Surface wellhead systems

Surface wellhead and Christmas-tree enquiries may involve complete equipment schedules or individual replacement components. Clear interface drawings, operating conditions and manufacturer references help distinguish a compatible sourcing requirement from a broader system-design task.

Define surface wellhead and tree requirements through equipment schedules, interface drawings and operating conditions.

Explore the enquiry scope.

  • Casing heads and spools
  • Tubing heads
  • Tubing hangers
  • Christmas-tree components
  • Adapters and connectors
  • Gate valves
  • Chokes
  • Wellhead seals and spares

Product families describe enquiry scope. Availability, technical suitability, documentation and delivery terms are confirmed for each requirement.

Where this enquiry fits

  • Tree valve, choke and adapter requirements
  • Hanger, seal and replacement-spare enquiries

Before requesting a quotation

Document the interfaces

Provide the wellhead arrangement, flange and connection details, hanger references and relevant drawings. Show which components are being retained and which are being replaced.

State the service envelope

Include working pressure, temperature, fluid service, material requirements and specified testing. Engineering acceptance of the assembled configuration remains essential.

Buyer questions

Can you review a single wellhead seal or hanger enquiry?

Yes. Include the full equipment reference, seal or hanger part number and a drawing where available. Identification must be resolved before a compatible option can be confirmed.

Are complete trees always available?

No live stock is implied. Configuration, source availability, technical review and delivery are assessed against the individual schedule.
