ASME B16.34 Hastelloy Alloy Swing Check Valve CW12MW No Return Valve 150LB 4 Inch

Introduction to Hastelloy Alloy Swing Check

Our ASME B16.34 compliant Hastelloy Alloy Swing Check Valve, made of CW12MW material, is designed for reliable performance. With a rating of 150LB and a 4-inch size, this no - return valve ensures unidirectional flow. The Hastelloy alloy offers exceptional corrosion resistance, making it ideal for harsh chemical processing environments, such as in petrochemical plants where exposure to corrosive fluids is common. Its robust construction and compliance with ASME standards guarantee safety and durability under high - stress conditions.

Advantages

Excellent corrosion resistance: Hastelloy alloys possess outstanding corrosion - resistant properties, especially in resisting various strong acids, alkalis, salt solutions, and seawater. For example, Hastelloy C - 276 has a high tolerance for chlorides, sulfuric acid, and nitric acid, far superior to ordinary stainless - steel valves. This can significantly extend the service life of valves in harsh corrosive environments.
Good high - temperature performance: It can maintain stable mechanical properties and organizational structure in high - temperature environments. For instance, Hastelloy B - 3 still has good corrosion resistance to reducing media at high temperatures and can be used for valves in high - temperature chemical reaction kettles. Some ordinary - material valves may experience problems such as deformation and reduced strength at high temperatures.
High strength and toughness: Hastelloy alloys have relatively high strength and toughness, enabling them to withstand large pressures and impacts. This characteristic allows Hastelloy alloy valves to operate reliably under harsh working conditions such as high - pressure and high - speed fluids, reducing the probability of safety accidents such as leaks caused by valve damage.

Main Materials

Application Area

Chemical Industry
Used in pipelines conveying corrosive media like sulfuric, hydrochloric, and nitric acids. They prevent media back - flow, safeguarding production and reducing equipment corrosion risks.
Petroleum and Gas
Employed in oil and gas extraction, transportation, and processing. Resist sulfide - and chloride - containing substances, ensuring pipeline system safety by preventing reverse flow.
Power Generation
In coal - fired plants, for desulfurization and denitrification systems against corrosive slurry and flue gas back - flow. In nuclear plants, in coolant circulation to ensure unidirectional coolant flow for reactor safety.
Marine Sector
Installed in shipboard seawater desalination and ballast water systems. Resist seawater corrosion and prevent its back - flow, protecting ship equipment and pipelines.
