F55 Duplex Steel Ball Valve, Duplex Steel Ball Valve, Ball Valve

Product Overview of F55 Duplex Steel Ball Valve:

The F55 duplex steel ball valve is an intermediate body, with left and right valve bodies, ball, valve stem and other main components processed from ASTM A182 F55 or S32760 and S27603 type forgings or bars. It is suitable for floating or fixed ball valves used in heat exchange equipment with water (including seawater, brine) as the medium.The F55 duplex steel ball valve is an intermediate component, with the left and right valve bodies, ball, valve stem, and other main components being processed from ASTM A182 F55 or S32760 as well as S27603 type forgings or bars. The material used in this valve belongs to super duplex stainless steel, equivalent to the domestic grade 022Cr25Ni7Mo4WCuN. It is suitable for floating or fixed ball valves used in heat exchange equipment with water (including seawater, brine) as the medium. It optimizes the ratio of ferrite to austenite (50% α phase, 50% γ phase). The material used for this valve is super duplex stainless steel, equivalent to the domestic grade 022Cr25Ni7Mo4WCuN. This steel increases the content of Mo and adds a small amount of W and Cu, thereby enhancing the ability to resist local corrosion. 

Advantages of F55 dual-phase steel ball valve products:

 It optimizes the ratio of ferrite to austenite (50% α phase, 50% γ phase).On the other hand, the F55 dual-phase steel ball valve reduces the percentage of C, thereby improving the weldability. This steel increases the content of Mo and adds a small amount of W and Cu, thereby enhancing the ability to resist local corrosion. 

Advantages of F55 dual-phase steel ball valve:

In addition, the F55 dual-phase steel ball valve reduces the percentage of C, thereby improving the weldability. Besides having excellent resistance to CI- and H2S stress corrosion cracking, it also has outstanding resistance to chloride pitting and crevice corrosion, and its strength is also very high, approximately twice that of austenitic stainless steel. Besides having excellent resistance to CI- and H2S stress corrosion cracking, it also has outstanding resistance to chloride pitting and crevice corrosion, and its strength is also very high, approximately twice that of austenitic stainless steel. Therefore, this product is widely used in oil transportation pipelines, chlor-alkali industry, fertilizer production, power plant flue gas desulfurization, and seawater desalination, etc. Therefore, this product is widely used in oil transportation pipelines, chlor-alkali industry, fertilizer production, power plant flue gas desulfurization, and seawater desalination, etc.

The F55 dual-phase steel ball valve, on the other hand, reduces the percentage of C, thereby improving the weldability. It not only has excellent resistance to CI- and H2S stress corrosion cracking, but also exhibits outstanding resistance to chloride pitting and crevice corrosion, and has high strength, approximately twice that of austenitic stainless steel. Therefore, this product is widely used in oil transportation pipelines, chlor-alkali industry, fertilizer production, power plant flue gas desulfurization, and seawater desalination, among other fields.
