API Valve Seat Incoloy 925 Nickel Based Forged Steel For Oil And Gas

The valve seat plays a vital role in the valve. It is mainly responsible for the following aspects:

• Sealing function: The valve seat is an important component inside the valve. It is located between the valve disc (or valve core) and the valve body. When the valve is closed, the valve disc is in close contact with the valve seat, forming a seal to prevent fluid medium from leaking through the valve. The material and design of the valve seat are crucial to the sealing performance of the valve.
• Supporting function: The valve seat also plays the role of supporting the valve disc to ensure that the valve disc stays stably in the valve body when it is closed, thereby maintaining the sealing state of the valve.
• Regulating function: In some types of valves, such as regulating valves, the valve seat also participates in regulating the flow of fluid. By changing the contact area between the valve disc and the valve seat, the flow cross-sectional area of ​​the fluid can be adjusted to control the flow rate.
• Guidance function: In some valve designs, the valve seat also provides guidance for the valve disc, ensuring that the valve disc moves smoothly during the opening and closing process and avoiding leakage caused by offset.
• Wear and corrosion resistance: Valve seats are usually made of wear and corrosion-resistant materials, such as stainless steel, nickel alloys or other special alloys, to ensure that they maintain their functionality and performance over long periods of use and under various operating conditions.

Incoloy Alloy 925 (UNS N09925) is an agehardenable nickel-iron-chromium alloy with additions of molybdenum, copper, titanium and aluminum.
The nickel content is sufficient for protection against chloride-ion stress corrosion cracking. The nickel, in conjunction with the molybdenum and copper, also gives outstanding resistance to reducing chemicals. The molybdenum aids with the resistance to pitting and crevice corrosion. The alloy’s chromium content provides resistance to oxidizing environments. The titanium and aluminum additions cause a strengthening reaction during heat treatment.
Incoloy alloy 925 is used in various applications requiring a combination of high strength and corrosion resistance. Because of the alloy’s resistance to sulfide stress cracking and stress-corrosion cracking in “sour” (H2S containing) crude oil and natural gas, it is used for down-hole and surface gaswell components including tubular products, valves, hangers, landing nipples, tool joints and packers. The alloy is also useful for fasteners, marine and pump shafting and high-strength piping systems
