Inconel 718 (UNS N07718) Tubing Hanger

The Inconel 718 (UNS N07718) Tubing Hanger is designed and manufactured for API 6A wellhead equipment applications. It is used to suspend and support tubing while providing reliable pressure control and sealing within wellhead systems. With high strength, good corrosion resistance and excellent high-temperature performance, this nickel-based alloy tubing hanger is suitable for oil and gas wellheads, Christmas trees and high-pressure pressure control equipment in onshore, offshore and demanding oil and gas production environments.

Key Features

• Withstands tubing weight and wellhead pressure loads for high-pressure oil and gas wells.
• Provides good resistance to various corrosive oil and gas media.
• Maintains high strength and stability at elevated temperatures.
• Precision-machined sealing and connection surfaces support reliable wellhead pressure control.
• Suitable for wellhead equipment exposed to long-term pressure and mechanical loading.
• Critical dimensions, sealing surfaces and connections can be precision-machined to specified requirements.

Typical Applications

• Used to suspend tubing and provide wellhead pressure control and sealing.
• Installed in Christmas tree and related wellhead equipment for tubing support and pressure isolation.
• Suitable for drilling, well completion and production operations in onshore oil and gas wells.
• Used in wellhead pressure control systems on offshore drilling and production platforms.
• Suitable for wellhead equipment in high-pressure, high-temperature and high-load oil and gas wells.
• Used for tubing suspension and sealing during well completion, workover and production operations.
