ASME B16.5 Flanges
We, orbit engineering co. is on a mission to fudge together resources and processes to invent new products that are quality driven and user-friendly. We home in on improving customer experience through improving our delivery standards. We are a manufacturer and supplier of ASME B16.5 Flanges that are also identified and referred as ANSI B16.5 Flanges by industries, manufacturers and engineers. Our ASME B16.5 Flanges tend to remain tough at moderately high-temperature services, while our Carbon Steel ANSI B16.5 Flanges have a higher resistance to local corrosion. The food processing and plastic industry is a major user of ASME B16.5 Alloy 20 Flanges that are not only economical but also withstand carbide precipitation. We supply ASME/ANSI B16.5 Flanges in Classes 150#, 300#, 600#,900#, 1500#, 2500#, etc.
