A bstract The Steele method of de‐airing sewer pipe features an air‐tight, inclosed mud chamber, fed by an inclosed chute from the de‐airing unit, which is connected in a straight line with a 12‐foot pug mill. Tempering clay with two wet pans has been discontinued. The plasticity has been increased, the pipes emerge straighter from the press, dry straighter, and are stronger and tougher with a resultant decrease in waste in house and kilns. The outer surface is smoother with practically no lamination or visible blisters. The crushing strength is increased and the absorption decreased.
