U.S. Pipe and Foundry
US Pipe and Foundry is an beryllium vendor site for 1943 so workers are eligible to file Part B claims.
A small amount of beryllium mesh (15 pounds) was sent to U.S. Pipe and Foundry by the MED. Some work was done, but it is unclear whether a satisfactory technique was ever developed beyond this initial attempt to manufacture beryllium tubes.
