• Bronze Composition: ASTM B62 specifies the composition of bronze materials used in valve manufacturing.
• Corrosion Resistance: The bronze alloy specified by ASTM B62 offers good resistance to corrosion, including salt fog corrosion. The combination of copper, tin, and lead provides a balance of strength and corrosion resistance.
• Testing: ASTM B62 valves are often tested using salt fog tests (ASTM B117) to evaluate their corrosion resistance. These tests simulate marine environments and provide a measure of the valve's durability in such conditions.
• Marine Systems: ASTM B62 ball valves are commonly used in marine applications, including shipboard systems, offshore platforms, and other maritime environments where corrosion resistance is crucial.
• Chemical Processing: These valves are also used in chemical processing plants where exposure to corrosive substances is common.
• Bronze Composition: ASTM B148 specifies the composition of bronze materials used in gate valves.
• Corrosion Resistance: The bronze alloy specified by ASTM B148 also offers good resistance to corrosion, including salt fog corrosion. The slightly different composition compared to ASTM B62 provides a balance of strength and corrosion resistance.
• Testing: ASTM B148 valves are also tested using salt fog tests (ASTM B117) to evaluate their corrosion resistance. These tests simulate marine environments and provide a measure of the valve's durability in such conditions.
Applications
• Marine Systems: ASTM B148 gate valves are commonly used in marine applications, including shipboard systems, offshore platforms, and other maritime environments where corrosion resistance is crucial.
• Water Treatment: These valves are also used in water treatment plants where exposure to corrosive substances is common.
