A182 F22 Globe Valve

‌A182 F22 globe valve‌ is an industrial valve with ‌ASTM A182 F22 chrome-molybdenum alloy steel‌ as the valve body material. It is designed for high temperature (≤593℃) and high pressure (≤16MPa) working conditions. It realizes pipeline cutoff, regulation and throttling control through vertical lifting of the valve disc. Its core features are as follows:

Structural composition
‌Main components‌

‌Valve body and valve cover‌: ASTM A182 F22 forged steel (split structure), the internal flow channel is precisely machined to reduce turbulence, and the pressure resistance is ≥16MPa; ‌

Valve disc and valve seat‌: The valve disc cone and valve seat are welded with Stellite alloy, and the sealing level reaches ASME B16.104 VI level, which can be sealed in both directions; ‌

Valve stem transmission‌: Nitrided alloy steel valve stem is adopted, and the trapezoidal thread is matched with the anti-blowout design, which is suitable for manual wheel or gearbox operation.
‌Functional components‌

‌Packing system‌: Double-layer flexible graphite packing + spring-loaded packing gland, adapting to thermal expansion and vibration conditions; ‌

Guide device‌: The valve stem guide sleeve adopts a copper alloy bushing to reduce friction resistance and prevent jamming.

Main Applications and functions

Oil and gas field development

Application scenarios: shale gas wellhead devices, high-pressure water injection systems;
Function: Resistant to corrosion from sulfur-containing media, blocking 16MPa high-pressure fluids through conical seals.

Thermal power generation

Application scenarios: supercritical boiler main steam pipeline (pressure ≥ 22.1MPa);
Function: Maintain seal integrity at 593℃ to prevent leakage caused by high-temperature creep.

Chemical production

Application scenarios: ammonia reactor inlet and outlet, high-temperature hydrogen pipeline;
Function: The bidirectional seal design adapts to medium counterflow, and the carbide sealing surface resists particle erosion.

Metallurgical industry

Application scenarios: blast furnace gas recovery system, high-temperature flue gas pipeline;
Function: The chromium-molybdenum steel valve body resists high-temperature oxidation, extending the valve life to 100,000 times of opening and closing.
