Received an inquiry for ASME B16.47 large size flanges from a new customer

On Saturday,I received an inquiry from a customer in India. The customer inquired for butt welding flange of large size, the standard is B16.47A series. ASME B16.47(Large Diameter Steel Flanges) is a standard for large diameter steel pipe flanges sized from NPS 26 through NPS 60.

After giving the quotation to the customer, we repeatedly communicated with each other about many details and requirements of the product, and I gave the customer professional answers and provided some pictures of the product that we had completed before.  The customer also compared the prices of other suppliers and finally chose us.
