Stress Problem Solved Installing 753 tube* and 4 ' / i in. tube sheet in hug· converter for operation over wide range of temperature·, it typical of difficult stres· problems solved by Β AW.
Field Construction Simplified Short-cuts in fabricating 100 ft. χ 20 ft. catalyst reactor in B&W shops saved erection time on location.
World's Largest Pipe Fabricated Supplying 45,000 tons of welded steel-plate pipe — ΛΥΐ to 30 ft. in diameter —for Hoover Dam presented many new problems of fabrication, transportation, handling and installation solved by B&W.

Fusion-Welded Boiler D r u m s - a B & W First The first welded boiler drums used in both marine and stationary boilers were built by B&W in 1930.
Designing and fabricating pressure vessels, drums,
tanks, towers, tubes, piping and related products is a
major activity at B&W — and has been for many years.
Here, practical solutions for new problems encountered in
the application of high pressure, high temperature
equipment are constantly being developed. In fact, B & W
pioneered many pressure vessel fabrication techniques
such as fusion welding, x-ray inspection, stress relieving,,
welded drums and streamlined openings.
Shown on these pages are a few examples of how
B&W pressure vessels and fabricating techniques have
solved new and difficult problems.
