Key features

This oilfield wellhead flange is strictly forged in accordance with API well control standards, rated for 5000PSI working pressure.

Made of high-strength alloy steel via integral forging, it features dense internal metal structure without porosity or cracks.

It can withstand long-term high-pressure load and instantaneous pressure impact, maintaining stable sealing performance for BOP stacks.

Subjected to overall heat treatment and anti-rust surface treatment, the flange boasts outstanding resistance to crude oil, drilling mud, hydrogen sulfide and salt fog corrosion.

It works reliably within a wide temperature range, perfectly adapting to high-temperature desert oilfields, cold plateau areas and offshore salt-spray environments.

Superior mechanical properties effectively prevent deformation, rust and fatigue damage for extended service life.

Product Q&A

Q:What standard and pressure level do your wellhead flanges comply with?

Our flanges are manufactured strictly per API well control standards, rated for 5000PSI working pressure. They adopt integral alloy steel forging technology and pass 1.5 times pressure hydrostatic test before delivery, fully matching BOP stacks and high-pressure well control systems.

Q:What is the installation requirement for high-pressure well control flanges?

The sealing surface must be kept clean without scratches or debris; tighten bolts diagonally and evenly in multiple passes to avoid uneven stress and medium leakage. Do not use oversize gaskets or damaged sealing rings during assembly.

Q:Can you provide official test reports and certification documents?

Yes. Each batch is accompanied by material test certificate, heat treatment record, hydrostatic pressure test report and API compliance statement, which can be used for third-party inspection, international bidding and export customs clearance.
