An 1888 improvement allowed for greater efficiency by casting the billet around a fire-proof brick core. However, it was difficult to drill holes with the precision needed to ensure uniformity in wall thickness. Seamless pipe was initially formed by drilling a hole through the center of a cylinder. Then the need arose for seamless metal pipes. He built machinery that employed his technique and many manufacturing plants adopted it. His technique allowed manufacturers to create continuous streams of pipe. Whitehouse’s method was improved upon in 1911 by John Moon. In 1825 Comelius Whitehouse developed the “butt-weld” process, the basis for modern pipe making. He joined the ends of flat iron pieces together to make a tube then welded the joints with heat. In 1824 James Russell patented a method for making metal tubes that was fast and inexpensive. Using barrels from discarded muskets he formed a continuous pipe delivering the coal gas to the lamps. In 1815 he invented a coal burning lamp system and wanted to make it available to all of London. William Murdock made the breakthrough leading to the modern process of pipe welding.
